1 Corinthians 9:18-20

Revised Standard Version Catholic Edition

¹⁸ What then is my reward? Just this: that in my preaching I may make the gospel free of charge, not making full use of my right in the gospel.

¹⁹ For though I am free from all men, I have made myself a slave to all, that I might win the more. ²⁰ To the Jews I became as a Jew, in order to win Jews; to those under the law I became as one under the law—though not being myself under the law—that I might win those under the law.
