1 Thessalonians 2:13

For this cause also thank we God without ceasing, because, when you received the word of God which you heard of us, you received it not as the word of men, but as it is in truth, the word of God, which effectually works also in you that believe.
Read Chapter 2

Augustine of Hippo

AD 430
Is it not apparently the beginning of the Thessalonians’ faith for which this same apostle thanks God, when he says, “Therefore, we also give thanks to God without ceasing, because when you had received the word which you heard from us, you received it not as the word of men, but (as it truly is) the word of God, which works in you, in which you have believed”? Why does he give thanks here to God? Certainly, it would be vain and meaningless if the person to whom he gives thanks for something is not the person who did it. But since this is not vain and meaningless, then certainly God, to whom he gives thanks for this work, is the one who brought it about that the Thessalonians, when they had received from the apostle the word by hearing it, received it not as the word of men but, as it truly is, as the word of God. Therefore, God works in the hearts of men, by that calling which is according to his purpose and of which we have said much, so that they would not hear the gospel in vain.

Augustine of Hippo

AD 430
We may compare the manner in which our own word is made as it were the speech produced by our body, through assuming that speech as a means of displaying itself to human senses, with the assumption of flesh by the Word of God as a means of displaying himself to human senses. Even as our human words are human thoughts not yet not changed into speech, so the Word of God was made flesh, but most assuredly not changed into flesh. Our words become vocalized. So the divine Word becomes flesh by an assumption of the outward form and not by a transformation of one thing into another. He, therefore, who desires to arrive at some sort of likeness—unlike as it must be at many points—of the Word of God, should not regard as final the human word that sounds upon the ear, either in its vocal utterance or in the unspoken thinking of it. The words of every audible language may also be the subject of thought without being vocalized. Poems may be repeated mentally, while the bodily mouth remains silent....

George Leo Haydock

AD 1849
The word of the hearing of God, which can only signify the word of God you heard from us. (Witham)

John Chrysostom

AD 407
It cannot be said, he says, that we indeed do all things unblamably, but you on the other hand have done things unworthy of our course of life. For in hearing us, you gave such heed as if not hearing men, but as if God Himself were exhorting you. Whence is this manifest? Because as he shows from his own temptations and their testimony, and the way in which he acted, that he did not preach with flattery or vainglory; so from their trials, he shows also that they rightly received the word. For whence, he says, unless ye had heard as if God were speaking, did ye endure such perils? And observe his dignity.

Knowing this first, that no prophecy of the scripture is of any private interpretation - 2 Peter 1:20
