that after He had been the minister of the Father in the creation
of all things--for by Him were all things made--in the last times,
emptying Himself He became man and was incarnate, although He was
God, and being made man He remained that which He was, God. He
assumed a body like our own, differing in this respect only, that
it was born of a Virgin and of the Holy Spirit."*

* De Principiis, Lib. I., Pref., 4. "Species vero eorum quae per
praedicationem apostolicam manifeste traduntur, istae sunt, Primo,
quod unus Deus est . . . tum deinde quia Jesus Christus ipse qui
venit, ante omnem creaturam natus ex Patre est. Qui cum in omnium
conditione Patri ministrasset (per ipsum enim omnia facta sunt);
novissimis temporibus se ipsum exinaniens, homo fictus incarnatus
est, cum Deus esset, et homo, factus mansit quod erat, Deus.
Corpus assumsit nostro corpori simile, eo solo differens,
quod natum ex Virgine et Spiritu Sancto est."

of which so many are convinced, and the announcement of the
judgment to come?"+
