Saint Jean Damascène
(Apologie de saint Jean Damascène contre ceux qui décrient les saintes images)
"Listen to me, people of all nations, men, women, and children, all of you who bear the Christian name: If any one preach to you something contrary to what the holy catholic Church has received from the holy apostles and fathers and councils, and has kept down to the present day, do not heed him. Do not receive the serpent’s counsel, as Eve did, to whom it was death. If an angel or an emperor teaches you anything contrary to what you have received, shut your ears."
