On the Catholic Priesthood
Christ could not give his divine nature to his clergy, for that would make them sons of God by nature as so many Gods. But he gave them his supernatural power, that is his Priesthood, his complete power over his mystic body the church. But the powers or faculties and the acts of creatures are not the same, for they cannot be infinitely perfect like unto God, who is the infinite Act, because of his infinity simplicity God cannot be divided.
In the Priesthood given to men the power of holy orders is the substance while jurisdiction is the regulation of the acts, or the exercise of these holy orders. By ordination or by holy orders we come forth from Christ. Then we are born into his eternal Priesthood. As Adam is the father of the race according to the flesh, so Christ is the father of Christians according to the Spirit. By natural birth we come forth from Adam while by supernatural generation we come forth from Christ. Each person baptized is born again of "Water and of the Holy Ghost." By confirmation we are strengthened by his Holy Spirit. But by holy orders we receive in a higher way the Holy Ghost the Spirit of Christ, for by that we enter in to his eternal Priesthood.
