Christology

"It is here usual to enquire, whether Christ as Mediator is inferior to the Father, and subordinate to him. But this controvery, it seems, may be easily settled among the orthodox: if the Mediator be considered in the state of humiliation, and the form of a servant, he is certainly inferior to the Father and subordinate to him; see John 14:28 "The Father is greater than I." Nay, we may look upon the very mediatorial office in itself as importing a certain economical inferiority, or subordination; as being to be laid down, when all things shall be perfectly finished, and God himself shall be all in all , I Cor 15:28."
