Ebionites

Extract frm Ligonier Ministries website, “One of the earliest Christian heresies was proclaimed by a group known as the Ebionites. The Ebionites were members of a Jewish sect that believed Jesus was the Messiah, but according to their understanding, the Messiah was merely a man. He was a great man, even the greatest possible man, anointed by the Spirit of God for the messianic office. Nevertheless, He was only a man, possessing only a human nature. The Ebionites found “support” for their position in texts such as Mark 1:9–11, which describes the anointing of Jesus with the Holy Spirit at His baptism. When this passage is read in light of the entire biblical witness, however, it is clear that while Jesus was a man, He was also far more than a man. The Ebionites did not pose a threat to Christian orthodoxy for long, as they died out by about the fifth century.”
