Now we must note concerning this first gospel sermon that on it the earliest believers stayed themselves. This was all that Adam had by way of revelation, and all that Abel had received. This one lone star shone in Abel's sky- he looked up to it and he believed. By its light he spelt out -sacrifice,- and therefore he brought of the firstlings of his flock and laid them upon the altar, and proved in his own person how the seed of the serpent hated the seed of the woman, for his brother slew him for his testimony.
