Basic Beliefs of Christian versus Muslim

Belief in	What Christians Believe	What Muslims Believe
God	God is three gods merged into one God. This one God is called a Trinity. However, to say that God is three is a blasphemy of the highest order. All three parts of the Trinity are "coequal" "co-eternal" and "the same substance." For this reason, this doctrine is described as "a mystery."	God is one God in the most basic, simple, and elementary meaning of the word. He has no children, no parents nor any equal. In Islam God is known by the name "Allah" and more than 99 other venerated names, such as "the Merciful," "the Gracious," "the All-Powerful," etc.
Jesus	The second member of the Triune God, the Son of the first part of the Triune God, and at the same time "fully" God in every respect.	A very elect and highly esteemed messenger of God. No Muslim is a Muslim if he does not believe this.
The Holy Spirit	The third member of the Triune God, but also "fully" God in every respect.	He is the angel Gabriel. The angel Gabriel is highly esteemed as the "Trustworthy Spirit"
Mary the mother of Jesus	A chaste and pious human woman who gave birth to Jesus Christ, the second member of the Trinity, the Son of God, and at the same time "fully" God Almighty in every respect.	A chaste and pious human woman who was chosen, purified, and preferred over all of the women of creation to be the one to give birth to Gods elect messenger Jesus through the command of God without any father whatsoever.
The Word	Part of God which was "with" God but also "fully" God and then became Jesus the Son of God.	God's command "Be!" which resulted in Jesus' conception in the womb of Mary without the need for a human father.
The Bible	Accepted as 100% the faultless word of God	Muslims believe in the books of the previous prophets including the "Torah" which was sent to Moses, the "Zaboor" (Psalms) which were given to David, the "Injeel" (Gospel) which was given to Jesus, and the Qur'an which was given to Muhammad However, Muslims are told that the previous scriptures were tampered with by mankind and the Bible should only be accepted in as far as it is confirmed by the Qur'an. It is to be treated with respect, however any statements which clearly oppose those of the Qur'an are to be rejected as the work of mankind.
The Qur'an	Varying beliefs ranging from it being a copy of the Bible to it being the work of Muhammad (pbuh), to it's being the work of Christians and Jews who were conspiring with Muhammad.	The last book of God sent to mankind. It was given the distinction of being personally guarded by God from human tampering. It is on a literary level never before seen by mankind. No Arab to this day has ever been able to meet it's challenge to "write a work similar to it." It shall remain safe from the tampering of mankind till the day of Judgment as a guidance for all Humanity.
Message of Jesus	That he was sent by God (who was at the same time "fully" Jesus) in order to die on the cross and save all mankind from the sin of Adam. Without this sacrifice all of humanity was destined to perish in the sin of Adam. After the crucifixion all that is required of humanity is faith without any works.	That he was sent by God as a messenger to the Jews in order to return them to the pure and true religion of Moses, and to relieve them of some of the regulations which had been placed upon them in ancient times. He taught them to have faith as well as works. Neither one can stand alone.
The second coming of Jesus.	Accepted. Originally expected to happen during the lifetime of the first disciples, many predictions have been made later and he is still expected at any moment. He is currently anticipated to arrive around the turn of the century (2000 C.E.)	Accepted. Jesus did not die but was raised up into heaven by God. He shall return to earth just before the Day of Judgment in order to kill the "False Messiah" and to establish peace and justice on earth. He will kill the pigs, break the cross, and call all humanity to Islam.
The original sin	All of humanity has inherited the sin of Adam. Only the death of the sinless offspring of God could erase this sin. No one is born clean, no matter if his life is only for a single day. Only baptism and faith in the death of Jesus can save one from this destiny.	There is no such thing. Humanity is created by God destined for heaven unless they chose to disobey Him and refuse His mercy. God can very trivially and effortlessly forgive the sins of all of Humanity no matter if they were to fill the lofty regions of the sky. Such a matter would be trivial and inconsequential for Him since He has already done much more than that such as creating everything we can ever see, hear or imagine. He loves to bestow His mercy and forgiveness on His creation and rewards the most trivial acts with the most tremendous rewards. In order to achieve God's reward one must have faith as well as works
The atonement	The sin of Adam was so great that God could not forgive it by simply willing it, rather it was necessary to erase it with the blood of a sinless innocent god named Jesus who was also "fully" God.	Adam "atoned" for his sin by saying "My Lord I have sinned and if you do not forgive me and have mercy upon me then I shall indeed have lost." So God forgave him. Similarly, all human beings have the door to forgiveness left open to them by God until the day they die. There are no intermediaries between mankind and God. If they sincerely repent to God, ask His forgiveness, and forsake their evil deeds before their hour comes then He shall forgive them and there is nothing more pleasing to Him than to forgive the sins of one who comes to Him in sincere repentance
The path to salvation	If you have faith in the atonement of Jesus for the sin of Adam which you have inherited then you shall be saved. You only need faith. No work is necessary.	If you have faith in God, believe in His messengers, and obey His commands then He shall multiply every single good deed that you do many, many times and erase your evil deeds, until on the Day of Judgment His mercy shall cause your good deeds to far outweigh your evil deeds and grant you passage into an ecstasy and Paradise so great that we can not even imagine it, to abide there eternally. In the Hereafter there is only reward and no work.
