Matthew Poole and continuators on 1 Corinthians 10:21

21 Ye cannot drink the cup of the Lord , and the cup of devils s: ye cannot be partakers of the Lords table, and of the table of devils .

We may either take the phrase as signifying all religio[illegible: 1 letter]s Communion under one great Act of Religion, or as particularly signifying, having a Communion with Christ in the Ordinance of the Lords Supper, which is called the Cup of the Lord, either because God hath instituted and appointed the drinking of it, or because it is done for the honour, glory, and remembrance of our Lord Christ, to remember his death until he come (as the Apostle speaketh Chap. 11.) This the Apostle tells them they could not drink of, that is, not rightly, and with a good conscience; or not really, no man that is an Idolater, or hath Communion with Idolaters in their idolatrous Acts, can have Communion with Christ:

The s[illegible: 1 letter]me is meant by the Table of the Lord, and the Table of Devils. So as I cannot see how either an idolatrous Church can be a true Church, or an Idolater a true Christian, unless we will assert, That a Body of people may be a true Church, that can have no Communion with Christ; or a man may be a true Christian, and yet have no Communion with Christ. Idolatry doubtless both divides the Soul from Christ, as he is the Head of a Believer, and as he is the Head of the Church. To call any Body of Idolaters a true Church, either Morally, or Metaphysically, is to say to those Ammi, You are the Lords people, to whom God hath said Loammi. Let them be what they will, the name of a Church belongeth not to them, if (as the Apostle affirmeth) they can have no Communion with Christ.
