Michael Ferrebee Sadler on The Word
... The most absolute declaration of the Godhead of Christ is in this Gospel, but no in the words of the Evangelist. It is the confession of St. Thomas, "My Lord and my God." The Evangelist is merely the recorder of this. So that, if his Gospel be a reliable record of facts, the most unqualified declaration of our Lord's Essential Divinity took place in His own presence, before His Ascension, and many years before any one book of the New Testament was in existence.
... [I]t removes all shadow of a doubt that when St. Matthew wrote "God with us," he meant "God with us" in the person of the Son or Word, as distinguished from the Father, for he gives us the historical facts of which St. John states the doctrinal reality. He tells us the circumstances under which the "Word was made flesh, and dwelt amongst us;" and so, as the Word was God, it was really and in no figure, God actually and personally "with us."
