Basil of Caesarea — as excerpted in the Catena Aurea on John 1:1

“(Hom. in Princ. Joan.) The Holy Ghost foresaw that men would arise, who should envy the glory of the Only-Begotten, subverting their hearers by sophistry; as if because He were begotten, He was not; and before He was begotten, He was not. That none might presume then to babble such things, the Holy Ghost saith, In the beginning was the Word.”
