1 Corinthians 12:12-13
12For as the body is one, and hath many members, and all the members of that one body, being many, are one body: so also
is Christ.
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.
Colossians 3:10-11
10And have put on the new
man, which is renewed in knowledge after the image of him that created him:
11Where there is neither Greek nor Jew, circumcision nor uncircumcision, Barbarian, Scythian, bond
nor free: but Christ
is all, and in all.
