An ordained minister, who's been in the service of the Lord for over 20 years, became a muslim. But that's not out of the ordinary, what's out of the ordinary is that she continues to claim Christianity while being a Muslim. This is her arguement, when she took the vows to be a muslim, The vows only proclaim that there is only one god and that Mohammed is God's prophet or messenger.

But, what about what Mohammed proclaims? The foundations of being saved in Islam is that you must prove your worthiness. Mohammed also proclaimed that Jesus is not the Messiah, he is only a prophet. Christianity is founded on the belief that we are all sinners, and only Jesus' can save us by believing that He died on the cross for our sins. It is impossible to be both a Muslim and a Christian. I don't think this woman has throughoughly thought it out. She's a living, walking contradiction.
