Matthew Poole and continuators on John 5:27

27 And hath given him authority to execute judgment also , because he is the Son of man .

To have the power of Life and Death, the Keys of both; to Rule and Govern the World, and to Judge it at the last day.

Acts 17.31. He hath appointed a day, in the which he will judge the world in righteousness, by that man whom he hath ordained, &c. So Phil. 2.8. Being found in fashion as a man, he humbled himself, and became obedient unto death, even the death of the Cross: wherefore God hath also highly exalted him, &c. Some think that the sense is, because he was that Son of Man, who was the Seed of the woman promised, Gen. 3.15. The Son of Man Prophecied of by Daniel, Chap. 7.13, 14. And that the term, Son of man (here) signifieth his Office as Mediator.
