I agree, the ‘allah’ of the Koran cannot be the God our Father and the Father of Jesus.
Totally true.
*Allah is alone, no trinity.
*Allah is not a "father" image, nor is he loving at all. He is merciful and compassionate but not loving.
*Also, we are God's beloved children and we consider Him our Father. That doesn't exist in Islam.
*Islam means "surrender" to Allah. There is none of that in Christianity...just LOVE.
*God IS love.
Allah is not.
God and Allah are as different as two deities can be.
But Vatican II Catholics agree with the Vatican II teaching that Catholics and Muslims worship the same God.
