1 Corinthians 10:21

Tertullian De Spectaculis

Nor do we dislike the temples less than the monuments: we have nothing to do with either altar, we adore neither image; we do not offer sacrifices to the gods, and we make no funeral oblations to the departed; nay, we do not partake of what is offered either in the one case or the other, for we cannot partake of God's feast and the feast of devils.[16]

Cyprian Epistle IX

Also the blessed apostle has said, "Ye cannot drink the cup of the Lord and the cup of devils; ye cannot be partakers of the Lord's table and of the table of devils."[5]

Cyprian Treatise III On the Lapsed

Also, the apostle testifies, and says, "Ye cannot drink the cup of the Lord and the cup of devils; ye cannot be partakers of the Lord's table and of the table of devils."[23]
