Matthew Poole and continuators on 1 Corinthians 11:29

29 For he that eateth and drinketh unworthily , eateth and drinketh damnation to himself , not discerning the Lords body

In the sense before mentioned, either having no remote right, or no present right to partake in that Ordinance, being an Unbeliever, or a resolved unholy, or ignorant person; or irreverently and irreligiously.

He eateth and drinketh [non-Latin text not transcribed], damnation, or judgment, it is no matter which we translate it; for if he bringeth Gods judgments upon him in this life, they will end in eternal damnation, without a timely repentance, but it is to himself, not to him that is at the same Table with him, unless he hath been guilty of some neglect of his duty to him:

And his guilt lieth here, that he doth not discern and distinguish betwixt ordinary and common Bread, and that Bread which is the representation of the Lords Body, but useth the one as carelesly, and with as little preparation and regard to what he doth, as he useth the other.

Marginal references: Or, judgment.
