Taken in context, 841 says PLAINLY that "together with us [Catholics], they [Muslims] adore the one, merciful God...."
No matter how much "context" is appealed to, it will not change the fact that 841 says exactly -- EXACTLY -- what it says: Catholics and Muslims worship the same God.
Question is, which "God" is being worshipped? The One, True, Living, Triune God, or "Allah"? Muslims do NOT worship the One Triune God; in fact, they claim that to do so is blasphemy because Allah has no son.
And the other glaring issue is captured in the very first quotation of 841:
"The plan of salvation also includes those who acknowledge the Creator, in the first place amongst whom are the Muslims;"
Hate to break this to you, but unless God calls them out of their idolatry and false religion of Islam, they're NOT included in the plan of salvation. Muslims do NOT acknowledge "the Creator" -- they deny him. And until their hearts are changed, they're damned just like any other person born since Adam and not saved.
You either worship God, or you do not. Worshipping Baal, or Molech, is NOT worshipping God imperfectly. It boils down to worshipping either God, or Satan.
The only context that's needed here is God's Word plainly stated in scripture. And 841 does not reflect that in the least little bit.

All I can do is suggest that perhaps your and the late Dr. Robert Reymond’s understanding of the “Catechism of the Catholic Church” is not as informed on all points as it could be.
