Jackson,
I'm sorry I don't have enough time to devote to this.
I'm attaching a link for Lumen Gentium, which was written by Pope John Paul, ex-Cathedra (as Pope) for anyone who may be really interested in what you say.
It has been believed that the God of Christianity, the Jewish religion and Islam, is the same God --- the God of Abraham, Isaac and Joseph.
Lumen Gentium only says that SOME outside of Christianity MAY BE SAVED, based on some conditions.
I do agree with this.
I'm not sure if you're asking if Muslims could be saved. If they are following their religion, I don't see how this could be possible since it is not a religion of peace.
IF they are following some aspects of their religion (as some Catholics do) and rcognize the one true God of love and mercy, then yes, I believe they could be saved.
This is for God to know and I DO NOT like to speak of salvation of soul's --- my remarks here are very general.
I'll post this and also the link to the above. It's not as simple as you make it out to be...
We will designate the above three sentences of LG 16 as LG 16b.
The Council here is teaching that under certain very specific conditions salvation is
possible for non-Christians. What are these conditions?
That non-Christians be not culpable for their ignorance of the Gospel.
That non-Christians seek God with a sincere heart.
That non-Christians try to live their life in conformity with what they know of God‘s will.
This is commonly spoken of as following the natural law or the light of conscience. It is
important to note, as the Council does, in order to avoid a Pelagian interpretation, that this is
possible only because people are ―moved by grace.‖
That non-Christians welcome or receive whatever ―good or truth‖ they live amidst—
referring possibly to elements of their non-Christian religions or cultures which may refract to
some degree that light that enlightens every man ( Jn 1:9). These positive elements are intended
to be ―preparation for the Gospel.‖ One could understand this to mean either a preparation for the
actual hearing of the Gospel or preparation for, perhaps, some communication of God by interior
illumination.
There is a very important doctrinal clarification contained in the footnote in this section
that references the Letter of the Holy Office to the Archbishop of Boston8
, which, issued in 1949,
gave an important ruling on Fr. Leonard Feeney‘s strict interpretation of the theological axiom
Extra Ecclesiam Nulla Salus.
This site will be helpful and also one could read Lumen Gentium on line.
