[Ali Imran]

You a Muslim quoting from a catholic website  You believe in it?
Nonetheless Catholics believe in one single God, who made himself known to the world (revelation) as three separate persons: God the Father, God the Son (Jesus) and God the Holy Spirit. This is known as the doctrine of the Trinity, and is a fundamental belief for all Catholics.

See I told you you will believe

Yes, I am clear about that doctrine and I hope you now know that you cannot use that analogy to explain the Trinity.

I've asked you this already. How do you reconcile that statement of Jesus who said the Father is the only true God?
