7:21Art thou called being a servant? care not for it: but if thou mayest be made free, use it rather.
7:22For he that is called in the Lord, being a servant, is the Lord's freeman: likewise also he that is called, being free, is Christ's servant.
12:13For by one Spirit are we all baptized into one body, whether we be Jews or Gentiles, whether we be bond or free; and have been all made to drink into one Spirit.
3:28There is neither Jew nor Greek, there is neither bond nor free, there is neither male nor female: for ye are all one in Christ Jesus.
6:8Knowing that whatsoever good thing any man doeth, the same shall he receive of the Lord, whether he be bond or free.
