There is one body; i.e. the church of Christ, Ephesians 1:23: see Colossians 3:15. And one Spirit; the self-same Spirit of Christ in that body by which all the members live and act, 1 Corinthians 12:11,13. Even as ye are called in one hope of your calling; one inheritance in heaven, to the hope of which ye are called, Colossians 1:12. Hope, for the thing hoped for, as Colossians 1:5: see 1 Peter 1:3,4.
