While then the better, the great and worthy and divine sacrifice was not yet available for men, it was necessary for them by the offering of animals to pay a ransom for their own life, and this was fitly a life that represented their own nature. Thus did the holy men of old, anticipating by the Holy Spirit that a holy victim, dear to God and great, would one day come for men, as the offering for the sins of the world, believing that as prophets they must perform in symbol his sacrifice, and shew forth in type what was yet to be. But when that which was perfect was come, in accordance with the predictions of the prophets, the former sacrifices ceased at once because of the better and true Sacrifice.
