Isn't this true that is in Islam it is not only love for your prophet as a condition of faith, but also obedience to all he says, because to obey your prophet is to obey Allah? Moreover, you must believe he is the best of creatures; the best of people or humans. Howis this not a worship of man?

I say Christians have the perfect form of monotheism, because unlike Muslims, we only show that kind of respect, love and obedience to God alone and not to a slave messenger or angel or any creature. Behold the Lord our God is one and we worship Him as one God with no partners; we don't have to say a Christian shahada; we don't have to mention any messengers with the one and only God like in the second part of the shahada. We will not commit that sin or shirk as you would call it. Islam doesn't have anything to offer Christianity; in fact, it appears to have imperfectly borrow from Christianity such truths as monotheism, heaven and hell, the virgin birth of Jesus and many other concepts that were written in the Bible first. I don't have a problem with what it borrowed, but I do with how it twists it and adds information. The only attempt at Biblical corruption I see toward the Scripture that came before is what Islam is trying to say about the torah and gospel. I am just calling a spade a spade! How can you see it differently?

Peace, grace and truth will prevail.
