1 Corinthians 1:22-24; 1 Corinthians 9:20; 1 Corinthians 10:32; 1 Corinthians 12:13
For indeed Jews ask for signs and Greeks search for wisdom;
but we preach Christ crucified, to Jews a stumbling block and to Gentiles foolishness,
but to those who are the called, both Jews and Greeks, Christ the power of God and the wisdom of God.
To the Jews I became as a Jew, so that I might win Jews; to those who are under the Law, as under the Law though not being myself under the Law, so that I might win those who are under the Law;
Give no offense either to Jews or to Greeks or to the church of God;
For by one Spirit we were all baptized into one body, whether Jews or Greeks, whether slaves or free, and we were all made to drink of one Spirit.
