19.  But lest thou shouldest think that He is in a like sense Father of the Son and of the creatures, Christ drew a distinction in what follows.  For He said not, “I ascend to our Father,” lest the creatures should be made fellows of the Only-begotten; but He said, My Father and your Father; in one way Mine, by nature; in another yours, by adoption.  And again, to my God and your God, in one way Mine, as His true and Only-begotten Son, and in another way yours, as His workmanship Compare Cat. vii. 7.  The Jerusalem Editor observes that the expression “My God” is understood by the Fathers generally as spoken by Christ in reference to His human nature, but Cyril applies this, as well as the other expression “My Father,” to the Divine nature.  So Hilary (de Trinit. iv. 53):  “idcirco Deus ejus est, quia ex eo natus in Deum est.”  Compare Epiphanius (Hær. lxix. 55)..  The Son of God then is Very God, ineffably begotten before all ages (for I say the same things often to you, that it may be graven upon your mind).  This also believe, that God has a Son:  but about the manner be not curious, for by searching thou wilt not find.  Exalt not thyself, lest thou fall:  think upon those things only which have been commanded thee Ecclus. iii. 22..  Tell me first what He is who begat, and then learn that which He begat; but if thou canst not conceive the nature of Him who hath begotten, search not curiously into the manner of that which is begotten.
