Emir Rishawi on the hypostatic union

Emir Rishawi, a convert from Islam, composed this fine reflection, directed at Muslims, trying to explain (I think) what Christians call the hypostatic union and the incarnation:

The mystery of Christ's person, as it seen through the New Testament, is epitomised in his relationship with God the Father. Christ is a man who is related to God through the heart of his message and the depth of his being. There is no difference between the person of Christ, the Word of God, and his message and being. His message is his being, and his being is his message. No one else could say the same, not even the prophets. Every man has his own being, and later he receives from God a message that is independent of his being. But with Jesus the message and the being are identical. His message is to reveal the will of God, manifest his love, and establish his kingdom.
