Warning and Encouragement Concerning the Lord's Supper

"Therefore whoever eats the bread or drinks the cup of the Lord in an unworthy manner, shall be guilty of the body and the blood of the Lord."

-1 Corinthians 11:27

Here is John Calvin's thoughts on the serious offensiveness of taking the Lord's Supper "in an unworthy manner":

"To eat unworthily, then, is to pervert the pure and right use of it by our abuse of it. Hence there are various degrees of this unworthiness, so to speak; and some offend more grievously, others less so. Some fornicator, perhaps, or perjurer, or drunkard, or cheat, (1 Corinthians 5:11,) intrudes himself without repentance. As such downright contempt is a token of wanton insult against Christ, there can be no doubt that such a person, whoever he is, receives the Supper to his own destruction. Another, perhaps, will come forward, who is not addicted to any open or flagrant vice, but at the same time not so prepared in heart as became him. As this carelessness or negligence is a sign of irreverence, it is also deserving of punishment from God. As, then, there are various degrees of unworthy participation, so the Lord punishes some more slightly; on others he inflicts severer punishment" (1 Corinthians in Calvin's Commentaries, pp.385-386).

And here is Calvin's thoughts on encouraging the weak to partake of the Lord's Supper:

"At the same time, it is not a perfect faith or repentance that is required, as some, by urging beyond due bounds, a perfection that can nowhere be found, would shut out for ever from the Supper every individual of mankind. If, however, thou aspirest after the righteousness of God with the earnest desire of thy mind, and, trembled under a view of thy misery, dost wholly lean upon Christ’s grace, and rest upon it, know that thou art a worthy guest to approach the table — worthy I mean in this respect, that the Lord does not exclude thee, though in another point of view there is something in thee that is not as it ought to be. For faith, when it is but begun, makes those worthy who were unworthy" (p.388).
