I Corinthians 12:12-14 -
"Just as a body, though one, has many parts, but all its many parts form one body, so it is with Christ. For we were all baptized by one Spirit so as to form one body—whether Jews or Gentiles, slave or free—and we were all given the one Spirit to drink. Even so the body is not made up of one part but of many."
Matthew 28:19-20
"Therefore go and make
disciples of all nations,
baptizing them in the name
of the Father and of the Son
and of the Holy Spirit, and teaching them to obey everything I have commanded you."
