1 Corinthians 10:16

10:16 Is not the cup of blessing that we bless a sharing in the blood of Christ? Is not the bread that we break a sharing in the body of Christ?

1 Corinthians 14:16

14:16 Otherwise, if you are praising God with your spirit, how can someone without the gift ¹  say “Amen” to your thanksgiving, since he does not know what you are saying?

[14:16]  ¹ tn Grk “how can someone who fills the place of the unlearned say ‘Amen.’”
