If Origen has put forth any other writings, you are to know that they and their author are alike condemned by me. The Lord have you in safe keeping, my lord and brother deservedly held in honour - St. Pope Anastasius I

St. Jerome called Pope St. Anastasius "a man of very rich poverty and apostolic zeal." He fought against heresies and heretics that threatened the doctrine of the Church, and he governed the Church with purity of life, abundance of doctrine, and perfect strictness of ecclesiastical authority.
