In the same way, the Lord has commanded that those who preach the gospel should receive their living from the gospel.
1 Corinthians 11:23-24
For I received from the Lord what I also passed on to you: The Lord Jesus, on the night he was betrayed, took bread, and when he had given thanks, he broke it and said, “This is my body, which is for you; do this in remembrance of me.”
1 Corinthians 8:8-9
But food does not bring us near to God; we are no worse if we do not eat, and no better if we do. Be careful, however, that the exercise of your freedom does not become a stumbling block to the weak.
