Atheist (and worse) websites often compare the Christian faith with "Mithraism" but any similarities are quite superficial. The teachings of Mithraism changed drastically after the advent of Christianity. What began as a secret cult (a "mystery religion") and was teamed with various other Hindu and Persian "gods," became much more like the teachings of the Christian faith in the first few centuries after the advent of Christ. It was done in the second century A.D., in order to try to keep cult members from going over to the Christian faith. Mithraism actually copied Christianity, not vice versa. Paganism is like that--they have little regard for the truth. They care much more about what is popular so that the cult leaders can prosper. There are many Christian websites which study the false charge that Christianity copied Mithraism. Here is one of them which begins with the assertion from someone who is losing faith in the exclusive nature of Christianity, followed by the proper response from a Christian perspective:
Did Christianity Steal From Mithraism?
The bottom line is--please don't listen to liars, bbyrd. Satan has always been a liar and he will tell any lie, no matter how outrageous, to try to keep humans from believing the truth.
There is much wrong in churches today. Many congregations are led by "hirelings" if you know what I mean by that. Some are becoming cult-like as well, in order that the leaders would prosper (look at all the mega church scandals). The truth is still there in the Bible but many congregations have only retained part of the truth of the Bible and a partial truth is not really truth. I see that Andy Stanley (the mega church pastor who heads huge and powerful North Point church in Atlanta) has said that he thinks that Christians
should not read and study the Old Testament! That is a teaching right out of hell--a "doctrine of demons". The understanding of God's work among His people Israel is vital to the foundation of the Christian faith. Like any pagan priest, Stanley is apparently going, not for what is true, but for what is popular (the Old Testament has been growing in unpopularity among "christians" for some time).
I suspect that we are in the final "gleaning" stage of God's harvest of souls from among the Gentiles. This should not surprise true Christians. We know that this "age of grace" has an "expiry date" as all of the ages of mortal man have had. The names of the Patriarchs, listed in Genesis 5, have always been there to inform us of God's plan for mortal man.
The Apostle Paul said, in the Book of Romans, that God has not forgotten His people, Israel. He said, once the "full number of Gentiles" has come in (Romans 11:25), that God would turn His attention to Israel. This is seen in the Book of Ezekiel--that God would initially begin a work in the Beautiful Land with unbelieving, ethnic Jews who appear as skeletons at first (the "dry bones" prophecy of Ezekiel 37). But then, He will put sinews and skin on them, ultimately, breathing life into them, by His Holy Spirit. The "lost" Tribes of Israel will come to faith in their Messiah and begin to unite with Judah in the Land, as they become the one people of Israel again.
The "times of the Gentiles" is closing and we are seeing the disintegration of the visible churches. This is the likely "falling away" before the "departure" of the true Church--the Bride. Interestingly, the language of 2 Thessalonians 2:3 can be taken both ways as "apostasy" (a "falling away" from the truth) and "departure" (of the true Church in the Rapture). Blessings to you bbyrd, as you seek the truth.
