How are the three major monotheistic religions both alike and different?

Christianity: They believe in a God, a God that is divided into three, the mystery of the Most Holy Trinity; they have the Bible as a sacred book, they accept that Judaism is prior to them and they deny Islam. Judaism, the oldest monotheistic religion, believes in one God and denies the other two major monotheistic religions (Christianity and Islam), believes in the wonders of God, and to be a Jew you have to take courses and have Jewish descent. His holy book is the Torah. He probably descends from the heresy of Akhenaten (Amenhotep IV) and his followers.For Islam, the main book is the Qur'an karim, believe in Judaism and Christianity, this religion is the last to emerge from among the monotheists as the prophet Muhammad is the last prophet. They believe in one God and only pray to Him.
