1CO 10:21

21 When you drink the [grape juice/wine in] [MTY] the cup [at the Lord’s Supper], you cannot participate in the [blessings that] the Lord [Jesus] brought to us and at the same time drink the [wine in the] [MTY] cup that people offer to demons! When you eat at the Lord’s table, you cannot participate in the blessings the Lord provided [MTY] when he died for us and at the same time participate in the things that represent demons [by eating food that has been sacrificed to idols]
