Religion

Who has, religious or not, looked into other religions, namely the Abrahamic one's; Judaism, Christianity & Islam, to compare & contrast each. What triggered my interest is that the Jews deny Christ & that the Christians deny Muhammad yet they are all said to stem from Abraham. I think history finds a way of repeating itself & would like to know if anyone has been left intrigued, baffled or shocked by other texts & please share your thoughts & findings. I'm currently in the process of reading the Quran, the chapter on Mary & Jesus & must say that the Quran, Bible & Torah are written very very differently, though there seems to be heaps of overlap.
