A brief debate with a Christian on the incarnation, that Imam Fakhr Al-Deen Al-Razi recounts in his Al-Arba’een fi Usul Al-Deen.
The Trinity
Christians claim that the single God exists as three distinct persons: the Father, the Son, and the Holy Spirit. Muslims claim that this belief is false because several absurdities follow from it.
The Incarnation of the Immutable God
Christians claim that Jesus is God, who entered the world to die for the sins of man. Muslims claim that this is a false belief, because this is a change on the part of God, and it is rationally impossible for a beginningless being to change.
