For the priest's lips should preserve knowledge, and they should seek the law from his mouth: for he is the messenger of the LORD of hosts.

AD 375
For neither may we address ourselves to almighty God, but only by Christ. In the same manner, therefore, let the laity make known all their desires to the bishop by the deacon, and accordingly let them act as he shall direct them. For there was no holy thing offered or done in the temple formerly without the priest. “For the priest’s lips shall keep knowledge, and they shall seek the law at his mouth,” as the prophet somewhere says, “for he is the messenger of the Lord God almighty.” .
