Hammer of the Heretics

“Whosoever shall say that there was a time when the Son of God was not, or that before he was begotten he was not, or that he was made of things that were not, or that he is of a different substance or essence [from the Father] or that he is a creature, or subject to change or conversion—all that so say, the Catholic and Apostolic Church anathematizes them.”- Council of Nicaea
