According to Ephesians 4:4-6 (Amplified Bible):
4) [There is] one body and one Spirit--just as there is also one hope [that belongs] to the calling you received--
5) [There is] one Lord, one faith, one baptism,
6) One God and Father of [us] all, Who is above all [Sovereign over all], pervading all and [living] in [us] all.
