For he that eateth and drinketh unworthily,.... As before explained, 1Co 11:27 "eateth and drinketh damnation to himself"; or guilt, or judgment, or condemnation; for by either may the word be rendered; nor is eternal damnation here meant; but with respect to the Lord's own people, who may through unbelief, the weakness of grace, and strength of corruption, behave unworthily at this supper, temporal chastisement, which is distinguished from condemnation with the world, and is inflicted in order to prevent it, 1Co 11:32 and with respect to others it intends temporal punishment, as afflictions and diseases of body, or corporeal death, as it is explained in 1Co 11:30.
This they may be said to eat and drink, because their unworthy eating and drinking are the cause and means of it. Just as Adam and Eve might be said to eat condemnation to themselves and posterity, because their eating of the forbidden fruit was the cause of it.
So the phrase, "does not eat condemnation", is used in the Persic version of Joh 3:18 for "is not condemned". And let it be observed, that such an one is said to eat and drink this judgment or condemnation to himself, and not another; he is injurious to nobody but himself: this may serve to make the minds of such easy, who are not so entirely satisfied with some persons who sit down with them at the Lord's table, when they consider that it is to their own injury, and not to the hurt of others they eat and drink:not discerning the Lord's body.
