Theophylact of Ohrid
Catena Aurea · Johannesevangelium 5
And hath given him authority to execute judgment also, because he is the Son of man. Marvel not at this: for the hour is coming, in the which all that are in the graves shall hear his voice, And shall come forth; they that have done good, unto the resurrection of life; and they that have done evil, unto the resurrection of damnation.
The Father granted the Son power not only to give life, but also to execute judgment. And hath given Him authority to execute judgment.
