The word Ebionite comes from the Hebrew אֶבְיֹון, which signifies “poor.” Different explanations more or less fanciful have been given of the reason for the use of the word in this connection. It occurs first in Irenæus (I. 26. 2), but without a definition of its meaning. Origen, who uses the term often, gives different explanations, e.g., in Contra Celsum, II. 1, he says that the Jewish converts received their name from the poverty of the law, “for Ebion signifies poor among the Jews, and those Jews who have received Jesus as Christ are called by the name of Ebionites.” In De Prin. IV. 1. 22, and elsewhere, he explains the name as referring to the poverty of their understanding. The explanation given by Eusebius refers to their assertion that Christ was only a common man, born by natural generation, and applied only to the first class of Ebionites, a description of whom follows. For the same name as applied to the second class (but see note 9) who accepted Christ’s supernatural birth, he gives a different reason at the end of the chapter, the same which Origen gives for the application of the name to Ebionites in general. The explanation given in this place is so far as we know original with Eusebius (something similar occurs again in Epiphanius, Hær. XXX. 17), and he shows considerable ingenuity in thus treating the name differently in the two cases. The various reasons do not of course account for the existence of the name, for most of them could have become reasons only long after the name was in use. Tertullian (De Præscr. Hær. 33, De Carne Christi, 14, 18, &c.) and Hippolytus (in his Syntagma,—as can be gathered from Pseudo-Tertullian, Adv. Hær. chap. 3, and Epiph. Hær. XXX.,—and also in his Phil. chap. 23, where he mentions Ebion incidentally) are the first to tell us of the existence of a certain Ebion from whom the sect derived its name, and Epiphanius and later writers are well acquainted with the man. But Ebion is a myth invented simply for the purpose of explaining the origin of Ebionism. The name Ebionite was probably used in Jerusalem as a designation of the Christians there, either applied to them by their enemies as a term of ridicule on account of their poverty in worldly goods, or, what is more probable, assumed by themselves as a term of honor,—“the poor in spirit,”—or (as Epiphanius, XXX. 17, says the Ebionites of his day claimed) on account of their voluntarily taking poverty upon themselves by laying their goods at the feet of the apostles. But, however the name originated, it became soon, as Christianity spread outside of Palestine, the special designation of Jewish Christians as such, and thus when they began to be looked upon as heretical, it became the name of the sect.
