In § 4 on the force of with God. πρὸς τὸν Θεόν.  “Note with admiration the exact appropriateness of every single word.  It is not said ‘The Word was in God.’  It runs ‘was with God.’  This is to set forth the proper character of the hypostasis.  The Evangelist did not say ‘in God,’ to avoid giving any pretext for the confusion of the hypostasis.  That is the vile blasphemy of men who are endeavouring to confound all things together, asserting that Father, Son, and Holy Ghost, form one subject matter, and that different appellations are applied to one thing.  The impiety is vile, and no less to be shunned than that of those who blasphemously maintain that the Son is in essence unlike God the Father.  The Word was with God.  Immediately after using the term Word to demonstrate the impassibility of the generation, he forthwith gives an explanation to do away with the mischief arising in us from the term Word.  As though suddenly rescuing Him from the blasphemers’ calumny, he asks, what is the Word?  The Word was God.  Do not put before me any ingenious distinctions of phrase; do not with your wily cleverness blaspheme the teachings of the Spirit.  You have the definitive statement.  Submit to the Lord.  The Word was God.”
