"The cup of jehovah "
In 1 Corinthians 8,6, St.Paul writes that there is only one God, the Father,and one Lord, Jesus Christ. In all his letters, St.Paul calls the Lord Jesus "kuploc" ( Lord) and " kuplov" (of the Lord). But why does he use the same term for Jehovah in 1 Corinthians 10,21? Why doesn't he use the Greek term for God the Father that he uses in other passages of his letters? Another question is this:why does Jesus say " my cup" and "my table" in Matthew 20,23 and Luke 22,30? Wouldn't it have been more correct to say the Father's cup? Did his words perhaps make Jehovah jealous?
