Bismillah: Assalamo Alikum.
My question in the first place was to LAST WORD who made the claim that Khadija was a Catholic, and so I asked him for the Islamic source that states this. But you came up with another approach of Shi’a website, I was interested to know whether there will be any authentic Islamic source which indicates that Khadija was a Catholic. I know that WARAQAH was a religious man who knew of the Scriptures of the Jews and Christian but there is no any record of translating those scriptures into Arabic in any of the authentic sources of Islam, he was a blind man. all what he said to Muhammad pbuh after he learned about his first revelation, that he is indeed the last prophet of God sent to mankind and that his name and description is mentioned in those scriptures, and he also predicted that pagans will fight him and drive him out of his home land, and he also said that if he lived till this moment, he would follow him and support his religion.
