9 God is faithful, through whom you were called into fellowship with His Son, Jesus Christ our Lord .
15 Yet if the unbelieving one leaves, let him leave; the brother or the sister is not under bondage in such cases, but God has called us to peace.
17 Only , as the Lord has assigned to each one, as God has called each, in this manner let him walk. And so I direct in all the churches. 18 Was any man called when he was already circumcised? He is not to become uncircumcised. Has anyone been called in uncircumcision? He is not to be circumcised.
20 Each man must remain in that condition in which he was called. 21 Were you called while a slave? Do not worry about it; but if you are able also to become free, rather do that. 22 For he who was called in the Lord while a slave, is the Lord's freedman; likewise he who was called while free, is Christ's slave.
24 Brethren, each one is to remain with God in that condition in which he was called.
27 If one of the unbelievers invites you and you want to go, eat anything that is set before you without asking questions for conscience' sake.
9 For I am the least of the apostles, and not fit to be called an apostle, because I persecuted the church of God.
