The rising of false Christs as predicted by Jewish Yeshua Hamashiach began in the 1st century. By carefully following the bible and history of the church, you’ll learn that in the same century, the Jewish messianic movement began in Jerusalem, a false Christianity movement began in Samaria, which identified their members as “Christians” but preached about “Jesus Christ” instead of Jewish Yeshua of Nazareth. As the Jewish believers in Yeshua were spreading from Jerusalem to other nations, the false Christians were spreading from Samaria to other parts of the world proclaiming a false [Jesus] Christ!
Paul compared these who will arise in the last days to oppose the truth of God with the story of Moses and Jannes and Jambres. Paul said the same way Jannes and Jambres withstood Moses in the presence of Pharaoh, would be the same method that the diviners, sorcerers, and the psychics who will secretly introduce destructive teachings in the church will resist the truth. Paul called them men of corrupt minds, reprobate concerning the faith (2Timothy3:8).
