John Chrysostom

"Hath given Him authority to execute judgment also." And wherefore doth He continually dwell upon "resurrection" and "judgment"? For He saith, "As the Father raiseth up the dead and quickeneth them, even so the Son quickeneth whom He will": and again, "the Father judgeth no man, but hath committed all judgment to the Son": and again, "As the Father hath life in Himself so hath He given to the Son to have life in Himself"; and again, "They that have heard the Voice of the Son of God shall live"; and here again, "Hath given to Him …
