In the following I offer a modernized English version of John Knox’s “Summary, According to the Holy Scriptures, of the Sacrament of the Lord’s Supper,” which is contained in Volume 3 of The Works of John Knox, published by The Banner of Truth Trust. The editor assigns this piece to the year 1550.
Here is briefly declared in sum, according to the Holy Scriptures, what opinion we Christians have of the Lord’s Supper, called the sacrament of the body and blood of our Savior Jesus Christ.
First, we confess that it is a holy action, ordained of God, in which the Lord Jesus, by earthly and visible things set before us, lifts us up unto heavenly and invisible things. And that when he had prepared his spiritual banquet, he witnesses that he himself was the living bread, with which our souls are fed unto everlasting life.
And therefore, in setting forth bread and wine to eat and drink, he confirms and seals up to us his promise and communion (that is, that we shall be partakers with him in his kingdom); and represents unto us, and makes plain to our senses, his heavenly gifts; and also gives unto us himself, to be received with faith, and not with the mouth, nor yet by transfusion of substance. But so through the virtue (i.e., the power) of the Holy Spirit, that we, being fed with his flesh, and refreshed with his blood, may be renewed both unto true godliness and to immortality.
And also that herewith the Lord Jesus gathers us unto a visible body, so that we are members of one another, and made altogether one body, whereof Jesus Christ is the only head. And finally that by the same Sacrament, the Lord calls us to remember his Death and Passion, to stir up our hearts to praise his most holy name.
Furthermore, we acknowledge that we ought to come unto this Sacrament reverently, considering that there is exhibited and given a testimony of the wonderful society and knitting together of the Lord Jesus and of the receivers; and also, that there is included and contained in this Sacrament, that he will preserve his Church. For herein we are commanded to show the Lord’s death until he comes.
Also, we believe that it is a Confession, wherein we show what kind of doctrine we profess; and what Congregation we join ourselves unto; and likewise, that it is a band of mutual love among us. And finally, we believe that all those who come unto this holy Supper must bring with them their conversion unto the Lord, by unfeigned repentance in Faith; and in this Sacrament receive the seals and confirmation of their faith; and yet must in no way think, that for this work’s sake their sins are forgiven.
And as concerning these words, Hoc est corpus meum, “This is my body,” on which the Papists depend so much, saying, That we must believe that the bread and wine are transubstantiated into Christ’s body and blood; We acknowledge that it is no article of our faith which can save us, nor which we are bound to believe upon pain of eternal destruction. For if we should believe that his very natural body, both flesh and blood, were naturally in the bread and wine, that should not save us, seeing many believe that, and yet receive it to their damnation. For it is not his presence in the bread that can save us, but his presence in our hearts through faith in his blood, which has washed our sins, and pacified his Father’s wrath toward us. And again, if we do not believe his bodily presence in the bread and wine, that shall not damn us, but the absence of our heart through unbelief shall damn us.
Now, if you would here object, that though it be truth, that the absence out of the bread could not damn us, yet we are bound to believe it because of God’s Word, saying, “This is my body,” which truth whoever does not believe as much as lies in him, makes God a liar: and therefore, of an obstinate mind not to believe his Word, may be our damnation. To this we answer, That we believe God’s Word, and confess that it is true, but not so to be understood as the Papists affirm. For in the Sacrament we receive Jesus Christ spiritually, as did the Fathers of the Old Testament, according to St. Paul’s saying. And if men would well weigh, how Christ, ordaining this Holy Sacrament of his body and blood, spoke these words Sacramentally, doubtless they would never so grossly and foolishly understand them, contrary to all the Scriptures, and to the expositions of St. Augustine, St. Jerome, Fulgentius, Vigilius, Origin, and many other godly writers.
