Brothers and sisters in the Lord, to help you prayerfully prepare for the Lord’s Supper, here are some selections from various Reformed Confessions and Catechisms on the Lord’s Supper:
The Westminster Confession of Faith
Chapter 29 Of the Lord’s Supper
1. Our Lord Jesus, in the night wherein he was betrayed, instituted the sacrament of his body and blood, called the Lord’s Supper, to be observed in his church, unto the end of the world, for the perpetual remembrance of the sacrifice of himself in his death; the sealing all benefits thereof unto true believers, their spiritual nourishment and growth in him, their further engagement in and to all duties which they owe unto him; and, to be a bond and pledge of their communion with him, and with each other, as members of his mystical body.
2. In this sacrament, Christ is not offered up to his Father; nor any real sacrifice made at all, for remission of sins of the quick or dead; but only a commemoration of that one offering up of himself, by himself, upon the cross, once for all: and a spiritual oblation of all possible praise unto God, for the same: so that the popish sacrifice of the mass (as they call it) is most abominably injurious to Christ’s one, only sacrifice, the alone propitiation for all the sins of his elect.
3. The Lord Jesus hath, in this ordinance, appointed his ministers to declare his word of institution to the people; to pray, and bless the elements of bread and wine, and thereby to set them apart from a common to an holy use; and to take and break the bread, to take the cup, and (they communicating also themselves) to give both to the communicants; but to none who are not then present in the congregation.
4. Private masses, or receiving this sacrament by a priest, or any other, alone; as likewise, the denial of the cup to the people, worshiping the elements, the lifting them up, or carrying them about, for adoration, and the reserving them for any pretended religious use; are all contrary to the nature of this sacrament, and to the institution of Christ.
5. The outward elements in this sacrament, duly set apart to the uses ordained by Christ, have such relation to him crucified, as that, truly, yet sacramentally only, they are sometimes called by the name of the things they represent, to wit, the body and blood of Christ; albeit, in substance and nature, they still remain truly and only bread and wine, as they were before.
6. That doctrine which maintains a change of the substance of bread and wine, into the substance of Christ’s body and blood (commonly called transubstantiation) by consecration of a priest, or by any other way, is repugnant, not to Scripture alone, but even to common sense, and reason; overthroweth the nature of the sacrament, and hath been, and is, the cause of manifold superstitions; yea, of gross idolatries.
7. Worthy receivers, outwardly partaking of the visible elements, in this sacrament, do then also, inwardly by faith, really and indeed, yet not carnally and corporally but spiritually, receive, and feed upon, Christ crucified, and all benefits of his death: the body and blood of Christ being then, not corporally or carnally, in, with, or under the bread and wine; yet, as really, but spiritually, present to the faith of believers in that ordinance, as the elements themselves are to their outward senses.
8. Although ignorant and wicked men receive the outward elements in this sacrament; yet, they receive not the thing signified thereby; but, by their unworthy coming thereunto, are guilty of the body and blood of the Lord, to their own damnation. Wherefore, all ignorant and ungodly persons, as they are unfit to enjoy communion with him, so are they unworthy of the Lord’s table; and cannot, without great sin against Christ, while they remain such, partake of these holy mysteries, or be admitted thereunto.
The Westminster Larger Catechism
Question 161. How do the sacraments become effectual means of salvation?
Answer: The sacraments become effectual means of salvation, not by any power in themselves, or any virtue derived from the piety or intention of him by whom they are administered, but only by the working of the Holy Ghost, and the blessing of Christ, by whom they are instituted.
Question 162. What is a sacrament?
Answer: A sacrament is an holy ordinance instituted by Christ in his church, to signify, seal, and exhibit unto those that are within the covenant of grace, the benefits of his mediation; to strengthen and increase their faith, and all other graces; to oblige them to obedience; to testify and cherish their love and communion one with another; and to distinguish them from those that are without.
Question 163. What are the parts of a sacrament?
Answer: The parts of a sacrament are two; the one an outward and sensible sign, used according to Christ’s own appointment; the other an inward and spiritual grace thereby signified.
Question 164. How many sacraments hath Christ instituted in his church under the New Testament?
Answer: Under the New Testament Christ hath instituted in his church only two sacraments, baptism and the Lord’s supper.
Question 168. What is the Lord’s supper?
Answer: The Lord’s supper is a sacrament of the New Testament, wherein, by giving and receiving bread and wine according to the appointment of Jesus Christ, his death is showed forth; and they that worthily communicate feed upon his body and blood, to their spiritual nourishment and growth in grace; have their union and communion with him confirmed; testify and renew their thankfulness, and engagement to God, and their mutual love and fellowship each with other, as members of the same mystical body.
Question 169. How hath Christ appointed bread and wine to be given and received in the sacrament of the Lord’s supper?
Answer: Christ hath appointed the ministers of his word, in the administration of this sacrament of the Lord’s supper, to set apart the bread and wine from common use, by the word of institution, thanksgiving, and prayer; to take and break the bread, and to give both the bread and the wine to the communicants: who are, by the same appointment, to take and eat the bread, and to drink the wine, in thankful remembrance that the body of Christ was broken and given, and his blood shed, for them.
Question 170. How do they that worthily communicate in the Lord’s supper feed upon the body and blood of Christ therein?
Answer: As the body and blood of Christ are not corporally or carnally present in, with, or under the bread and wine in the Lord’s supper, and yet are spiritually present to the faith of the receiver, no less truly and really than the elements themselves are to their outward senses; so they that worthily communicate in the sacrament of the Lord’s supper, do therein feed upon the body and blood of Christ, not after a corporal and carnal, but in a spiritual manner; yet truly and really, while by faith they receive and apply unto themselves Christ crucified, and all the benefits of his death.
Question 171. How are they that receive the sacrament of the Lord’s supper to prepare themselves before they come unto it?
Answer: They that receive the sacrament of the Lord’s supper are, before they come, to prepare themselves thereunto, by examining themselves of their being in Christ, of their sins and wants; of the truth and measure of their knowledge, faith, repentance; love to God and the brethren, charity to all men, forgiving those that have done them wrong; of their desires after Christ, and of their new obedience; and by renewing the exercise of these graces, by serious meditation, and fervent prayer.
Question 172. May one who doubteth of his being in Christ, or of his due preparation, come to the Lord’s supper?
Answer: One who doubteth of his being in Christ, or of his due preparation to the sacrament of the Lord’s supper, may have true interest in Christ, though he be not yet assured thereof; and in God’s account hath it, if he be duly affected with the apprehension of the want of it, and unfeignedly desires to be found in Christ, and to depart from iniquity: in which case (because promises are made, and this sacrament is appointed, for the relief even of weak and doubting Christians) he is to bewail his unbelief, and labor to have his doubts resolved; and, so doing, he may and ought to come to the Lord’s supper, that he may be further strengthened.
Question 173. May any who profess the faith, and desire to come to the Lord’s supper, be kept from it?
Answer: Such as are found to be ignorant or scandalous, notwithstanding their profession of the faith, and desire to come to the Lord’s supper, may and ought to be kept from that sacrament, by the power which Christ hath left in his church, until they receive instruction, and manifest their reformation.
Question 174. What is required of them that receive the sacrament of the Lord’s supper in the time of the administration of it?
Answer: It is required of them that receive the sacrament of the Lord’s supper, that, during the time of the administration of it, with all holy reverence and attention they wait upon God in that ordinance, diligently observe the sacramental elements and actions, heedfully discern the Lord’s body, and affectionately meditate on his death and sufferings, and thereby stir up themselves to a vigorous exercise of their graces; in judging themselves, and sorrowing for sin; in earnest hungering and thirsting after Christ, feeding on him by faith, receiving of his fullness, trusting in his merits, rejoicing in his love, giving thanks for his grace; in renewing of their covenant with God, and love to all the saints.
Question 175. What is the duty of Christians, after they have received the sacrament of the Lord’s supper?
Answer: The duty of Christians, after they have received the sacrament of the Lord’s supper, is seriously to consider how they have behaved themselves therein, and with what success; if they find quickening and comfort, to bless God for it, beg the continuance of it, watch against relapses, fulfill their vows, and encourage themselves to a frequent attendance on that ordinance: but if they find no present benefit, more exactly to review their preparation to, and carriage at, the sacrament; in both which, if they can approve themselves to God and their own consciences, they are to wait for the fruit of it in due time: but, if they see they have failed in either, they are to be humbled, and to attend upon it afterwards with more care and diligence.
The Belgic Confession
Article 33: The Sacraments
We believe that our gracious God, taking account of our weakness and infirmities, has ordained the sacraments for us, thereby to seal unto us His promises, and to be pledges of the good will and grace of God towards us, and also to nourish and strengthen our faith; which He has joined to the Word of the gospel, the better to present to our senses both that which He declares to us by His Word and that which He works inwardly in our hearts, thereby confirming in us the salvation which He imparts to us. For they are visible signs and seals of an inward and invisible thing, by means whereof God works in us by the power of the Holy Spirit. Therefore the signs are not empty or meaningless, so as to deceive us. For Jesus Christ is the true object presented by them, without whom they would be of no moment.
Moreover, we are satisfied with the number of sacraments which Christ our Lord hath instituted, which are two only, namely, the sacrament of baptism and the holy supper of our Lord Jesus Christ.
Article 35: The Sacrament of the Lord’s Supper
We believe and confess that our Savior Jesus Christ did ordain and institute the sacrament of the holy supper to nourish and support those whom He has already regenerated and incorporated into His family, which is His Church.
Now those who are regenerated have in them a twofold life, the one corporal and temporal, which they have from the first birth and is common to all men; the other spiritual and heavenly, which is given them in their second birth, which is effected by the Word of the gospel, in the communion of the body of Christ; and this life is not common, but is peculiar to God’s elect. In like manner God has given us, for the support of the bodily and earthly life, earthly and common bread, which is subservient thereto and is common to all men, even as life itself. But for the support of the spiritual and heavenly life which believers have He has sent a living bread, which descended from heaven, namely Jesus Christ, who nourishes and strengthens the spiritual life of believers when they eat Him, that is to say, when they appropriate and receive Him by faith in the spirit.
In order that He might represent unto us this spiritual and heavenly bread, Christ has instituted an earthly and visible bread as a sacrament of His body, and wine as a sacrament of His blood, to testify by them unto us that, as certainly as we receive and hold this sacrament in our hands and eat and drink the same with our mouths, by which our life is afterwards nourished, we also do as certainly receive by faith (which is the hand and mouth of our soul) the true body and blood of Christ our only Savior in our souls, for the support of our spiritual life.
Now, as it is certain and beyond all doubt that Jesus Christ has not enjoined to us the use of His sacraments in vain, so He works in us all that He represents to us by these holy signs, though the manner surpasses our understanding and cannot be comprehended by us, as the operations of the Holy Spirit are hidden and incomprehensible. In the meantime we err not when we say that what is eaten and drunk by us is the proper and natural body and the proper blood, of Christ. But the manner of our partaking of the same is not by the mouth, but by the spirit through faith. Thus, then, though Christ always sits at the right hand of His Father in the heavens, yet does He not therefore cease to make us partakers of Himself by faith. This feast is a spiritual table, at which Christ communicates Himself with all His benefits to us, and gives us there to enjoy both Himself and the merits of His sufferings and death: nourishing, strengthening, and comforting our poor comfortless souls by the eating of His flesh, quickening and refreshing them by the drinking of His blood.
Further, though the sacraments are connected with the thing signified nevertheless both are not received by all men. The ungodly indeed receives the sacrament to his condemnation, but he does not receive the truth of the sacrament, even as Judas and Simon the sorcerer both indeed received the sacrament but not Christ who was signified by it, of whom believers only are made partakers.
Lastly, we receive this holy sacrament in the assembly of the people of God, with humility and reverence, keeping up among us a holy remembrance of the death of Christ our Savior, with thanksgiving, making there confession of our faith and of the Christian religion. Therefore no one ought to come to this table without having previously rightly examined himself, lest by eating of this bread and drinking of this cup he eat and drink judgment to himself. In a word, we are moved by the use of this holy sacrament to a fervent love towards God and our neighbor.
Therefore we reject all mixtures and damnable inventions which men have added unto and blended with the sacraments, as profanations of them; and affirm that we ought to rest satisfied with the ordinance which Christ and His apostles have taught us, and that we must speak of them in the same manner as they have spoken.
The Heidelberg Catechism
Question 66. What are the sacraments?
Answer: The sacraments are holy visible signs and seals, appointed of God for this end, that by the use thereof, he may the more fully declare and seal to us the promise of the gospel, viz., that he grants us freely the remission of sin, and life eternal, for the sake of that one sacrifice of Christ, accomplished on the cross.
Question 67. Are both word and sacraments, then, ordained and appointed for this end, that they may direct our faith to the sacrifice of Jesus Christ on the cross, as the only ground of our salvation?
Answer: Yes, indeed: for the Holy Ghost teaches us in the gospel, and assures us by the sacraments, that the whole of our salvation depends upon that one sacrifice of Christ which he offered for us on the cross.
Question 68. How many sacraments has Christ instituted in the new covenant, or testament?
Answer: Two: namely, holy baptism, and the holy supper.
Question 75. How art thou admonished and assured in the Lord’s Supper, that thou art a partaker of that one sacrifice of Christ, accomplished on the cross, and of all his benefits?
Answer: Thus: That Christ has commanded me and all believers, to eat of this broken bread, and to drink of this cup, in remembrance of him, adding these promises: first, that his body was offered and broken on the cross for me, and his blood shed for me, as certainly as I see with my eyes, the bread of the Lord broken for me, and the cup communicated to me; and further, that he feeds and nourishes my soul to everlasting life, with his crucified body and shed blood, as assuredly as I receive from the hands of the minister, and taste with my mouth the bread and cup of the Lord, as certain signs of the body and blood of Christ.
Question 76. What is it then to eat the crucified body, and drink the shed blood of Christ?
Answer: It is not only to embrace with believing heart all the sufferings and death of Christ and thereby to obtain the pardon of sin, and life eternal; but also, besides that, to become more and more united to his sacred body, by the Holy Ghost, who dwells both in Christ and in us; so that we, though Christ is in heaven and we on earth, are notwithstanding “flesh of his flesh and bone of his bone” and that we live, and are governed forever by one spirit, as members of the same body are by one soul.
Question 77. Where has Christ promised that he will as certainly feed and nourish believers with his body and bleed, as they eat of this broken bread, and drink of this cup?
Answer: In the institution of the supper, which is thus expressed: “The Lord Jesus, the same night in which he was betrayed, took bread, and when he had given thanks, he brake it, and: said: eat, this is my body, which is broken for you; this do in remembrance of me. After the same manner also he took the cup, when he had supped, saying: this cup is the new testament in my blood; this do ye, as often as ye drink it, in remembrance of me. For, as often as ye eat this bread, and drink this cup, ye do show the Lord’s death till he come.” 1 Cor.11:23-26. This promise is repeated by the holy apostle Paul, where he says “The cup of blessing which we bless, is it not the communion of the blood of Christ? The bread which we break, is it not the communion of the body of Christ? For we being many are one bread, and one body: for we are all partakers of that one bread.” 1 Cor.10:16,17.
Question 78. Do then the bread and wine become the very body and blood of Christ?
Answer: Not at all: but as the water in baptism is not changed into the blood of Christ, neither is the washing away of sin itself, being only the sign and confirmation thereof appointed of God; so the bread in the Lord’s supper is not changed into the very body of Christ; though agreeably to the nature and properties of sacraments, it is called the body of Christ Jesus.
Question 79. Why then doth Christ call the bread “his body”, and the cup “his blood”, or “the new covenant in his blood”; and Paul the “communion of body and blood of Christ”?
Answer: Christ speaks thus, not without great reason, namely, not only thereby to teach us, that as bread and wine support this temporal life, so his crucified body and shed blood are the true meat and drink, whereby our souls are fed to eternal life; but more especially by these visible signs and pledges to assure us, that we are as really partakers of his true body and blood by the operation of the Holy Ghost as we receive by the mouths of our bodies these holy signs in remembrance of him; and that all his sufferings and obedience are as certainly ours, as if we had in our own persons suffered and made satisfaction for our sins to God.
Question 80. What difference is there between the Lord’s supper and the popish mass?
Answer: The Lord’s supper testifies to us, that we have a full pardon of all sin by the only sacrifice of Jesus Christ, which he himself has once accomplished on the cross; and, that we by the Holy Ghost are ingrafted into Christ, who, according to his human nature is now not on earth, but in heaven, at the right hand of God his Father, and will there be worshipped by us. But the mass teaches, that the living and dead have not the pardon of sins through the sufferings of Christ, unless Christ is also daily offered for them by the priests; and further, that Christ is bodily under the form of bread and wine, and therefore is to be worshipped in them; so that the mass, at bottom, is nothing else than a denial of the one sacrifice and sufferings of Jesus Christ, and an accursed idolatry.
Question 81. For whom is the Lord’s supper instituted?
Answer: For those who are truly sorrowful for their sins, and yet trust that these are forgiven them for the sake of Christ; and that their remaining infirmities are covered by his passion and death; and who also earnestly desire to have their faith more and more strengthened, and their lives more holy; but hypocrites, and such as turn not to God with sincere hearts, eat and drink judgment to themselves.
Question 82. Are they also to be admitted to this supper, who, by confession and life, declare themselves unbelieving and ungodly?
Answer: No; for by this, the covenant of God would be profaned, and his wrath kindled against the whole congregation; therefore it is the duty of the christian church, according to the appointment of Christ and his apostles, to exclude such persons, by the keys of the kingdom of heaven, till they show amendment of life.
