It is therefore a mode of speaking which ought to be carefully marked, when we hear, that the voice of God and the words of Haggai were reverently attended to by the people.—Why? Inasmuch, he says, as God had sent him; as though he had said, that God was heard when he spoke by the mouth of man. And this is also worthy of being noticed, because many fanatics boast, that they allow regard to the word of the Lord, but are unwilling to give credit to men, as that would be even preposterous; and they pretend, that in this way what belongs to the only true God is transferred to creatures. But the Holy Spirit most easily reconciles these two things—that the voice of God is heard when the people embrace what they hear from the mouth of a Prophet. Why so? because it pleases God thus to try the obedience of our faith, while he commits to man this office. For if the Lord was pleased to speak himself, then justly might men be neglected: but as he has chosen this mode, whosoever reject God’s Prophets, clearly show that they despise God himself. There is no need of inquiring here, why it is that we ought to obey the word preached or the external voice of men, rather than revelations; it is enough for us to know that this is the will of God. When therefore he sends Prophets to us, we ought unquestionably to receive what they bring.
