The Epistles of Ignatius

For though some would have deceived me according to the flesh, yet the Spirit, as being from God, is not deceived. For it knows both whence it comes and whither it goes, and detects the secrets [of the heart]. For, when I was among you, I cried, I spoke with a loud voice: Give heed to the bishop, and to the presbytery and deacons. Now, some suspected me of having spoken thus, as knowing beforehand the division caused by some among you. But He is my witness, for whose sake I am in bonds, that I got no intelligence from any man. But the Spirit proclaimed these words: Do nothing without the bishop; keep your bodies as the temples of God; love unity; avoid divisions; be the followers of Jesus Christ, even as He is of His Father.
