44 Cannon, you seem like an alright person; but you also seem to be a lil' misguided. Not an idiot but, yeah, misguided...
Or, maybe, you're right and I'm wrong...
Islam, Christianity and the other major monotheistic religion of today, Judaism (although maybe to a lesser degree), all have the same core; Abraham. As well as this, they all share prophets.Islam and Christianity have some differences in their core. Christianity believes in one divine teacher which has already been and gone whose teachings will remain till the end of time. Islam on the other hand is less set in stone, believing in multiple prophets.
Also, Islam also believes in one devine teacher. Muhamed (wrong spelling?) wrote down what Gabriel told him; Gabriel, in turn, conveyed the message of Islam's teacher: God.
Technically, the same can be said of Christianity. The nature of Jesus is still not entirely understood. Was he the son of God, God himself, or something else? In any case, one of the roles played by 'Jesus' - apart from salvation - was to convey the message of God.
Islam and Christianity are the same 'at core'. Their differences lie in their practices and their interpretations of both God and the purpose of those who mediate what God says.
