Islam is an ideology disguised as a religion, which it is most assuredly is not. Islam claims to have ties to Abraham though there are no verifiable facts to that claim. The biblical story that Abraham's illegitimate son, Ishmael, was the ancestor of Mohammed has in no way been proven. Islam claims there is only one god, allah, though there is no evidence of miracles or prophecies in islam as there are with the God of the Bible. In fact, allah was one of a circle of rocks worshipped by pagan Arabs when Mohammed raided then captured a village, allowing those who agreed to follow him to live, while he put to death those who refused to follow him. In what some might call a brilliant strategic move, Mohammed selected one of the rocks called allah to be his god, discarding the rest thereby setting the stage for the so-called "religion".
Islam accepts Jesus as prophet but specifically denies his divinity. This fact alone proves that islam does NOT worship the God of Catholicism, for all Catholics accept Jesus Christ as the only begotten Son of God. By denying the divinity of Christ, islam proves it is not a religion but a man made story.
Islam was spread primarily by the sword giving those conquered by muslims three options. First, the conquered could convert to islam and live. Or the conquered could become slaves, pay the jizyya or tax, and live as slaves. Lastly, the conquered could refuse the first two options which would be an immediate death sentence. Hardly much of a free choice in anyone's view.
Muslims are allowed to lie if it is for the good of islam, a doctrine called taqiyya. This is clearly opposed to God's commandment of thou shalt not lie, which has no exceptions.
Muslims are commanded to fight all non muslims until all is islam, suggesting that an eternal war or jihad is to be waged until the entire world comes under the control of jihad. Hardly a peaceful way to gain converts which is in total contrast to God's command to spread the gospel to all corners of the world. Any muslim who renounces islam is an apostate and is put to death. So much for free will. Islam considers women to be property of men, just like animals, and men can beat the women just like animals. They can also kill the women if they cause undo shame on the man or the family, hardly in keeping with God's true commandment. Muslim men can also rape non muslim women as they are considered infidels and inferior, therefore property to be treated as such.
An in depth study and comparison between islam and Catholicism requires a lengthy explanation, so for the sake of time, I will conclude by saying that islam is not a religion at all, but a satanic death cult created in the feeble mind of a desert peasant who longed for power and recognition. Knowing a little about Judaism and Christianity, he plagiarized both, perverting and twisting both to his warped goals as driven by the devil, for who else could drive an illiterate nomad to forge an ideology that would become a force that could eventually threaten the entire western world with enslavement.
We must not forget that God has used kingdoms more than once to chastise Israel when its people refused to honor God's covenant, so it is not hard to see how God could be using the muslims to chastise the world given the unspeakable crime of mass abortions committed against His most precious, innocent unborn children. Surely we deserve that chastisement though I pray we may yet stay His righteous anger though the intercession of His most Blessed Mother, for the failure to do so is too terrible to contemplate.
O Mary conceived without sin, pray for us who have recourse to thee. Amen.
