John Chrysostom
Up to this point he unfolded the type. Now he confidently presents Christ as surpassing everything that was real among the Jews.
If the type of Christ is such, and if he is so much higher not only than the priests but even than the forefather of the priests, what shall be said of the Truth? Do you see with what force he proves His superiority?
See, he says, how great he is, to whom even the patriarch Abraham gave a tithe from the best of his chosen spoils. The spoils are called chosen.
It cannot be said that Abraham gave it to him as a participant in the war. For it says: he met Abraham and blessed him, returning from the slaughter of the kings. Clearly Melchizedek had remained at home, and Abraham gave him the firstfruits of what he himself had acquired.
