It's just [their] channel of communication with God that differs. (Christians-Christ Jesus; Roman Catholics-Mary; Muslims- Mohommed and Jews-I am not sure of).
Now, that would be insulting if it weren't so ignorant.
1. Outside of a purely Evangelical context, using "Christian" to mean solely the evangelicals is a mistake. Better terms to distinguish from Catholics are "Protestants" or "evangelical Christians", depending on what you mean. To imply that Catholics aren't Christian is . . . let's just say impolite, for now.
2. It's interesting that you list Christ as a conduit to God, when nearly all Christians believe that He IS God.
3. If you are clumsily asserting that non-Catholics don't pray to Mary and the other saints--asking, BtW, not for them to exert their own power but to pray to God
with us--whereas Catholics do, perhaps you're right. I don't know as much about Protestant theology as I perhaps should. Anybody want to enlighten me? Or do I have to go Netsearching?
If your point is that Catholics neglect Christ in favor of Mary, you are wrong. The repeatedly emphasized point is that Mary leads to Christ. Only for the ignorant does she become the Goddess. (Admittedly, some zealots who should know better can encourage that misbelief.)
4. Lest others be mistaken, as I was: There are an awful lot of ways to spell the name of "the Prophet", and
Mohommed is yet another of them, though comparatively uncommon--less than 45K hits on Google.
5. Muslims do not consider Mohammed as the sole conduit to God. Like Christians, they pray directly to Allah (aka God).
6. Jews admit no conduit to G-d. Like Muslims and Christians (of all stripes, including the Mormons so prominent where I live), they pray to Him.
What I cannot understand is the hate existing between these believers--especially in Ireland between Protestants and Catholics and in the western worl[d] between the Christians and the Muslims.
Socioeconomics more than religion in itself.
I say each to his own and leave them each other in PEACE.
Don't we all! But it doesn't help to mischaracterize others' beliefs.
