The Epistles of Cyprian

² Since, therefore, the Lord threatens these torments, these punishments in the day of judgment, to those who obey the devil and sacrifice to idols, how does he think that he can act as a priest of God who has obeyed and served the priests of the devil; or how does he think that his hand can be transferred to the sacrifice of God and the prayer of the Lord which has been captive to sacrilege and to crime, when in the sacred Scriptures God forbids the priests to approach to sacrifice even if they have been in lighter guilt; and says in Leviticus: “The man in whom there shall be any blemish or stain shall not approach to offer gifts to God?” Also in Exodus: “And let the priests which come near to the Lord God sanctify themselves, lest perchance the Lord forsake them.” And again: “And when they come near to minister at the altar of the Holy One, they shall not bring sin upon them, lest they die.” Those, therefore, who have brought grievous sins upon themselves, that is, who, by sacrificing to idols, have offered sacrilegious sacrifices, cannot claim to themselves the priesthood of God, nor make any prayer for their brethren in His sight; since it is written in the Gospel, “God hears not a sinner; but if any man be a worshipper of God, and does His will, him He hears.” Nevertheless the profound gloom of the falling darkness has so blinded the hearts of some, that they receive no light from the wholesome precepts, but, once turned away from the direct path of the true way, they are hurried headlong and suddenly by the night and error of their sins.
