I would love a conversation on the different interpretations of monotheism, you say stricter, some would say simpler. Islam views Jesus(Isa) for all intents and purposes the exact way Christians do with the exception of his divinity. Jews deny Christ as anything but a charlatan.
Kitab at tawhid
by Muhammad ibn Abd al Wahhab(yes as in
wahhabiism) is probably the best book on Islamic monotheism written. For the "pure" monotheist. However, the trinitarian view layed out by Tertullian really outside of word choice isn't any different than the 99 Names of Allah as recorded in Sahih al Muslim (3rd in line as far as hadiths go but one of the most reliable, "sahih" denoting this).
See Muslims don't like the anthropomorphic attributions that Jesus, and Christianity give to God. Which is quite confusing given that they view Isa, Jesus as a messanger and Prophet) I find it funny, that anything that they disagree with is simply cast aside as "a corruption", a misunderstanding, or an innovation. I find it funny that they agree and believe in the Injil, which is the gospel of Jesus, which they don't happen to have a copy of handy. Instead they say the Biblical gospels, I'm thinking the synoptic gospels primarily are a "distortion" of the Injil. I'm simplifying all of this you understand as I don't know how well versed you are on these matters so some of what I wrote is the general gist more so than say, a word for word recreation of their beliefs.
Christianity, that is Catholicism doesn't believe that anyone else can redeem you either other than God, Jesus, as Son in the trinitarian view IS God. The rest are intercessions. The common protester argument is that these are not needed and that they should not be done. I say, fine, don't but then don't ask your Pastor, or your friends at Men's group, or anyone else you know to pray for you either. IT IS THE SAME THING. The difference being in the communion of Saint the Saints that are asked to intercede are believed to already be IN THE PRESENCE of God. Who better to pray for you than the individuals sitting in front of the Big Guy, eh?
