ORIGENlANS, a Sett of antient Heretics, who even furpafsM the Abominationsof the Gwfiics.
St. Epifhanius fpeaks of 'em as ilill fubfifting in his time ; but in very fmall Number, He feems to fix their Rife about the time of the great Origen ; but does not fay they took their Name from him. He diftinguifhes 'em from the Or ige7iijis, whom he derives from Origen Adamantus - adding, indeed, that they firlt took their Name from one Ongen ; by which he intimates, that it was not the Great. And St. Augujiine fays exprefly it was another.
_Asto their Doctrine, all that'Modefty will allow to ba faid, is, that they rejected Marriage; that they ufed feve- ral Apocrypha! Books, as the Acts of St, Andrew, &c. and that to excufe their open Crimes, they accufed the Catho- lics of doing the fame in private.
ORIGENISTS, Followers of the Errors of Origen, St. Efiphanius infiils very largely on the Errors of this Father 5 but as he declares himfelf too warmly againlt him, there may be fomewhat of Exaggeration in what he fays. Nor do St. Jerom, or Theophilus of Alexandria, feem to have kept their Zeal within the proper bounds in fpeaking of Origen. For which Reafon, no doubt, it was that St. Chry- fojiom himfelf was accufed of being an Origen-ji, becaufe not fo vehemently bent againft him. Origenifm fpread itfelf chiefly among the Monks of Egypt,

Original Sin, is that Crime we become guilty of at our Birth; by the Imputation of Adam's Difobedience* See Sin.
Father Uallebranch accounts for Original Sin from Natural Caufes, thus ; Men at this day retain, in the Brain, all the Traces and Impreflions of their firlt Parents. For as Ani- mals produce their like, and with like Traces in the Brain 5 whence it is that Animals of the fame kind have the fame Sympathies and Antipathies, and do the fame things on the fame Ojcafions : So our firlt Parents, after °their Tranfgreffion, received fuch deep Traces in their Brain, by the lmpreflion of fenfible Objects, that 'twas very poffible they might communicate 'em to their Children.
Now, as 'tis neceffary, according to the Order eilablim- ed by Nature, that the Thoughts of the Soul be con- formable to the Traces in the Brain ; it may be faid that as foon as we are form'd in the Womb, we are infected with the Corruption of our Parents : For having Traces in the Brain like thofe of the Perfons who gave us being 7 'tis neceffary we have the fame Thoughts, and the fame- Inclinations with regard to fenfible Objects.
Thus, of courfe," we muft be born with Concupifcence, and Original Sin. With Concupifcence, if that be nothing but the natural Effort the Traces of the Brain make on the Mind to attach it to fenfible things ; and with Original Sm^ if that be nothing but the Prevalcncy of Concupifcence 5 nothing in effect, but thefe Effects confider'd as Victorious and as Matters of the Mind and Heart of the Child.
