Ebionites
Ebionites (Ancient Greek: Ἐβιωναῖοι, romanized: Ebiōnaîoi, derived from the Hebrew word אֶבְיוֹנִים, ʾEḇyōnīm, meaning 'the poor' or 'poor ones') were an adoptionist Mosaic law-observant Jewish-Christian movement that existed in and around Transjordan during the early centuries of the Common Era. Since original writings by Ebionites are scarce, fragmentary and contested, much of what is known or conjectured about them derives from the polemical reports by their proto-orthodox and later orthodox Christian opponents, the Church Fathers (Irenaeus, Origen, Eusebius, and Epiphanius of Salamis), who generally portrayed Ebionites as a heretical sect doctrinally distinct from other judaizing Jewish-Christian sects, such as the Nazarenes.
