In the Book of Genesis it is written that Abel the righteous man brought fat portions of his flock (Gen.4: 4). The Apostle explains this, saying: "By faith Abel offered to God a more excellent sacrifice than Cain" (Heb.11: 4). Here, we ask: How did Abel know the idea of offering sacrifices to God? From where did he get that faith? There was no written Law at his time. Undoubtedly, he received this idea through Tradition from his father Adam who had received it from God Himself. This took place fourteen centuries before Moses wrote about sacrifices and burnt offerings.
