Part Five: The Nature of God
Section 21 — The Trinity: What It Actually Claims
What the Trinity Does NOT Claim
- Three gods (tritheism) — Christianity explicitly rejects this
- That God is divided into three parts
- That Jesus is a second god alongside the Father
- That 1+1+1=3
What the Trinity Actually Claims
There is one God. This one God exists in three persons — Father, Son, and Holy Spirit. Three distinct persons who share one divine nature. A God who is intrinsically relational — whose very nature is the eternal love between the persons of the Trinity — is a God for whom love is not an add-on but an expression of what He essentially is.
✖ Muslim Response: This is Greek philosophy imposed on the simple truth of God's oneness. Tawhid is clear.
✔ How to respond: The Trinitarian doctrine was not imported from Greek philosophy — it was driven by the unavoidable data of the life, death, and resurrection of Jesus. Jewish monotheists who would have been horrified at any suggestion of a second god found themselves worshipping Jesus and had to account for it. The Trinity is the answer they arrived at by taking both monotheism and Jesus's identity completely seriously at the same time.
Section 22 — The Incarnation: Why God Became Man
"The Son of God became the Son of Man so that sons of men might become sons of God." — Athanasius of Alexandria, c. 318 AD
The only way to repair a corrupted nature is to introduce an uncorrupted nature from the inside. That is what the Incarnation is. God entering human nature, from the inside, to heal it — to provide the one fully human and fully righteous life that Adam's descendants could not produce — and to offer that life as a gift.
✖ Muslim Response: A God who becomes a baby, who gets hungry, who can be killed — this is not the God of the universe.
✔ How to respond: The Incarnation does not claim that God ceased being eternal when He became flesh. It claims He added human nature to His divine nature without abandoning either. The capacity to enter human experience without ceasing to be God demonstrates a more extraordinary capacity than a God who can only remain at a transcendent distance. He who holds the universe in His hand lay in Mary's arms — not because the universe fell out of His hand, but because He could do both simultaneously.
