Someone asked, “What is the relationship of Judaism, Christianity and Islam?” God authored three religious systems in sequence, beginning with the creation of mankind. Patriarchy is the first period of religious history, extending from Adam and Eve through possibly Acts 10 (except for the Israelites) with the conversion of Cornelius’s household. After about 2,500 years following creation, God instituted Judaism (on Mt. Sinai) for the Israelites. Approximately 1,500 years later, God brought about Christianity through the ministry of Jesus Christ—culminating with His death, burial, resurrection, ascension back to Heaven and coronation. At that time, Judaism ended (as far as God was concerned) for the Jews, but Gentiles may have been amenable to Patriarchy a few years more until the Gospel was preached to them. In any case, by now, all men now living are obligated to practice Christianity.
Christianity is nearly 2,000 years old, having begun in the first century—about A.D. 33. Islam, though, began around A.D. 600—600 years after the beginning of Christianity. Whereas Patriarchy, Judaism and Christianity were each authored by God in sequence, God did not author Islam, and therefore, it is not related to Patriarchy, Judaism or Christianity. The only direct connection between Judaism, Christianity and Islam is that the proponents of each of those religions revered the city of Jerusalem.
