1 Corinthians 7:17-19

17 Only let each person live the life the Lord has assigned him and live it in the condition he was in when God called him. This is the rule I lay down in all the congregations.
18 Was someone already circumcised when he was called? Then he should not try to remove the marks of his circumcision. Was someone uncircumcised when he was called? He shouldn't undergo b'rit-milah.
19 Being circumcised means nothing, and being uncircumcised means nothing; what does mean something is keeping God's commandments.
