Papias of Hierapolis

The presbyters, the disciples of the apostles, say that this is the gradation and arrangement of those who are saved, and that they advance through steps of this nature; and that, moreover, they ascend through the Spirit to the Son, and through the Son to the Father; and that in due time the Son will yield up His work to the Father, even as it is said by the apostle, "For He must reign till He hath put all enemies under His feet. The last enemy that shall be destroyed is death."

And when all things shall be subdued unto Him, then shall the Son also Himself be subject unto Him that put all things under Him, that God may be all in all."
