The Hebrew Roots Movement which encompasses Messianic Judaism and both in fact are one and the same, just packaged differently in order to deceive more people, is gaining momentum in these last days. While Messianic Judaism is more Christ oriented, it is really just a stepping stone to the HRM. Many Jews who have accepted Christ as Messiah, are attempting as the Jewish Christians in the early church, to mesh Grace with Judaism under the Old Covenant, making all inclusive with one another the Works of the Law, as well as the ordinances, such as the Sabbath and other holy days and combining them with Christianity. The great Apostle Paul had much to say about this in his letters to the early church. Read the book of Galatians where Paul addresses this heresy and warns the early church that if they follow this teaching, they have fallen from grace.
