22 It will not be out of place here if we review the full meaning of the Apostle's teaching upon this subject. Let us take, then, each single sentence and expound it, that we may grasp the entire Mystery by comprehending it in its fullness. The words of the Apostle are, For since by man came death, by man came also the resurrection of the dead. For as in Adam all die, so also in Christ are all made alive. But each in his own order: Christ the firstfruits, then they that are Christ's at His coming. Then comes the end, when He shall have delivered the Kingdom to God, even the Father, when He shall have emptied all authority and all power. For He must reign until He put all enemies under His feet. The last enemy that shall be conquered is death. But when He says, All things are put in subjection, He is excepted Who did subject all things unto Him. But when all things have been subjected to Him, then shall He also Himself be subjected to Him, that did subject all things unto Him, that God may be all in all.
