Justin Martyr:
“We are no longer purified by the blood of sheep and goats, by the ashes of a heifer, or by the offerings of fine flour. Rather, we are purified by faith through the blood of Christ.”
Lactantius:
“He sent his Son as an ambassador to men, so He could turn them from their unholy and vain worship to the knowledge and worship of the true God. He also sent Him so that He could turn their minds from foolishness to wisdom, and from wickedness to deeds of righteousness.”
