1 Corinthians 9:16-19 New American Bible (Revised Edition) (NABRE)
16 If I preach the gospel, this is no reason for me to boast, for an obligation has been imposed on me, and woe to me if I do not preach it! 17 If I do so willingly, I have a recompense, but if unwillingly, then I have been entrusted with a stewardship. 18 What then is my recompense? That, when I preach, I offer the gospel free of charge so as not to make full use of my right in the gospel.
All Things to All. 19 [a]Although I am free in regard to all, I have made myself a slave to all so as to win over as many as possible.
