The bloody sacrifice was a type of Christ all through the OT, starting with the skins God covered the nakedness of Adam and Eve with..He ordered bloody sacrifices for the covering/ forgiveness of sin throughout the OT .. Abel did as God commanded and took the best of his animals and slay it , Cain disobeyed and brought a false sacrifice.. one that could never cover his sin . I do nor much care what Cramer thinks unless he is infallible :)
Hebrews 11:4 By faith Abel offered to God a better sacrifice than Cain, through which he obtained the testimony that he was righteous, God testifying about his gifts, and through faith, though he is dead, he still speaks.
And that's before we get to the relationship between Our Lords Sacrifice and the Mass.
