1 Cor 10:16

10:16 The cup of blessing . . . The bread that we break. These statements about the Lord’s Supper demonstrate the significance of taking part in a distinctively religious meal. Just as it would be impossible to take the Lord’s Supper and claim that it had no religious significance, so it is naive for the Corinthians to think they can participate in temple feasts without being involved in idolatry. Another point is that the unity “in the body of Christ” symbolized by taking the bread and wine excludes union with idols. See “The Sacraments” at Matt. 28:19.
