According to the Catechism of the Catholic Church, paragraph 841, Catholics and Muslims ‘‘adore the one, merciful God.’’
841 The Church’s relationship with the Muslims. “The plan of salvation also includes those who acknowledge the Creator, in the first place amongst whom are the Muslims; these profess to hold the faith of Abraham, and together with us they adore the one, merciful God, mankind’s judge on the last day.”
Although I would certainly not disagree that there are some in the Muslim community who might attain salvation through Christ, I think that Islam (like Mormonism) degrades the image of God by rejecting the Trinity:
*“They do blaspheme who say: Allah is one of three in a Trinity: for there is no god except One Allah. If they desist not from their word (of blasphemy), verily a grievous penalty will befall the blasphemers among them,” (Quran 5:73, Yusuf Ali).
Since the Trinity is the true Biblical doctrine of God, how can the Muslims who deny the Trinity “adore the one, merciful God”? Furthermore in Christianity, Jesus is divine in nature while the Quran says the opposite:
They indeed have disbelieved who say: Lo! Allah is the Messiah, son of Mary. Say: Who then can do aught against Allah, if He had willed to destroy the Messiah son of Mary, and his mother and everyone on earth? Allah’s is the Sovereignty of the heavens and the earth and all that is between them. He createth what He will. And Allah is Able to do all things," (Quran 5:17, Pickthal).
In conclusion, I think paragraph 841 of the Catechism needs to be revised, though I look forward to hearing your views
