Has God given over some of his authority (forgiveness of sins, resurrection of the dead, the Last Judgement) to Jesus?

Answer: This question is asked only by someone who assumes that Jesus of Nazareth was simply a man and no more. However, the Christian faith believes that Jesus himself is the personification of God’s wisdom. God himself as wisdom forgives sins, resurrects the dead and judges on the Last Day through the personification of wisdom which we recognise in Jesus Christ (read in this connection: The Letter to the Colossians 1:12-23, particularly 19-20).
