Doesn 1 Corinthians 9:14 say that preachers should be fully supported by the gospel?
No. “Living of the gospel” is not “living from law principles.” See context 9:12-19. • A. The gospel is wholly of grace and none of law (Rom. 1:17). • B. If this were a direct command by Jesus that gospel workers should be supported full-time by tithing or otherwise, then Paul disobeyed a direct command of Jesus. • C. If this is a reference to Matthew 10:10 or Luke 10:7 (as most claim), those chapters describe gospel workers who were beggars while performing gospel work. They are descriptions of Old Testament prophets, or rabbis, not Levites and priests.
