Introduction to Islam

"The religion of Islam is not named after a person as in the case of Christianity which was named after Jesus Christ, Buddhism after Gotama Buddha, Confucianism after Confucius, and Marxism after Karl Marx. Nor was it named after a tribe like Judaism after the tribe of Judah and Hinduism after the Hindus. Islam is the true religion of God."

Comparative Religion

Christianity and Islam

God - Look at how God is described in the Bible and Qur'an
Divinity of Jesus - "I left Christianity because I clearly saw that the two natures, divine and human, are mutually exclusive, like that of a circle and a square. To ask whether God can "become a human being" is like asking if God can "create a square circle"-that is, they refer to nothing meaningful, such that we could ask if it could exist, but rather are a simple confusion of words."
Trinity - "One may say with one's lips: 'I believe that God is one, and also three'--but no one can believe it, because the words have no sense." (What is Religion by Leo Tolstoy).
Bible - "I can't accept the Bible as God's Word because it contains hundreds of problems and contradictions that can't be solved"
Original Sin - Natural Justice Demands That Everyone Be Answerable For His/Her Own Wrongs And Not For Others' Misdeeds - AND GOD IS NOT UNJUST!
Crucifixion - is there nothing that Christianity can offer mankind, other than the blood and gore of Jesus?
Muhammad in the Bible - There are so many prophecies about the prophet Muhammad(pbuh) in the Bible, that you have to be aware of it. In fact, the word itself, Muhammad, exists in the bible.
Bridging the Gap between Islam and Christianity - A summary of most of the above, the main difference between Islam and Christianity is the divinity of Jesus. This article looks at the differences.
