Nestorianism

Islam was preceded by Christianity, which, as attested by the authentic inscription of Si-ngan-fu, penetrated into the western provinces under the form of Nestorianism about the seventh century.

Some countenance too is given to the same view of the Eucharist, at least in some parts of his works, by Origen, whose language concerning the Incarnation also leans to what was afterwards Nestorianism.

It was not properly a question respecting the faith, but whether certain writings, then a hundred years old, were or were not favourable to Nestorianism.

Pulcheria throughout was opposed to Nestorianism, as to every doctrine which flavored of Greek metaphysics, while Eudocia is credited with being an advocate of the new doctrine.

The original ebionitism had died away, but its spirit and central doctrine reappeared in Nestorianism.
