Since some have desperately attempted to defend Vatican II’s teaching that Muslims and Catholics worship the same God, we will offer some further brief thoughts on this matter in light of the definition of Islam. We and others have made similar points before, but when one reads the definition of Islam it really should strike one how false and heretical this teaching of Vatican II is. Catholics and Muslims don’t have the same God.
“Muhammad’s religion is called Islam, meaning submission to the will of God. Its adherents are Muslims. Their creed is utterly simple, stark and hard-lined as mountains against a desert sunset, proclaimed five times every day from the minarets in every Muslim city: la ilaha illa-l-Lah, Muhammadun rasulul-Lah (‘There is no God whatsoever but Allah; Muhammad is the messenger of God.’) Merely to pronounce this creed makes a man a Muslim. Thereafter the penalty for apostasy is death, with no questions asked and no exceptions granted.” (Warren H. Carroll, A History of Christendom, Vol. 2, p. 217)
Let’s think about this: “There is no God whatsoever but Allah,” according to the Muslims. And Muhammad is his messenger. This means, therefore, that according to the Muslims the “God” for whom Muhammad is the messenger is the only God. As they say, “There is no other God whatsoever” except the one for whom Muhammad was messenger. Muhammad said that God had no Son (Koran, Surah XIX, “Mary”), and denied the Trinity. Therefore, it is an undeniable fact that the Muslims worship no God “whatsoever” except the one who has no Son and is not a Trinity – the one for whom Muhammad spoke. Vatican II worships the same “God.”
Vatican II, Lumen Gentium # 16: “But the plan of salvation also embraces those who acknowledge the Creator, and among these the MUSLIMS are first; they profess to hold the faith of Abraham AND ALONG WITH US THEY WORSHIP THE ONE MERCIFUL GOD WHO WILL JUDGE MANKIND ON THE LAST DAY.”
The Catholic Church, on the other hand, worships a different God – the one and only true God – Father, Son and Holy Ghost. In light of the definition of Islam (that Muslims worship no other “god” whatsoever except the one who has no Son and is not a Trinity), we can see that Vatican II’s teaching – that it worships the same “god” – is a denial of the Trinity and the Son of God. There is absolutely no way to deny that the teaching of Vatican II is blatantly false and heretical. The same wicked heresy is taught in John Paul II’s new catechism, and many other post-Vatican II documents.
