There is a difficulty in following the argument in the foregoing quotations.  F. Combefis, the French Dominican editor of Basil, would boldly interpose a “not,” and read ‘whenever he does not instruct us concerning the Father.’  But there is no ms. authority for this violent remedy.  The Benedictine Editors say all is plain if we render “postquam nos de patre erudivit.”  But the Greek will not admit of this.
