seed of Abraham according to the
flesh which He received from His Mother. But His Mother paid tithes
in Abraham. Therefore for a like reason did Christ.

Obj. 3: Further, "in Abraham tithe was levied on that which needed
healing," as Augustine says (Gen. ad lit. x). But all flesh subject
to sin needed healing. Since therefore Christ's flesh was the subject
of sin, as stated above (A. 7), it seems that Christ's flesh paid
tithes in Abraham.

Obj. 4: Further, this does not seem to be at all derogatory to
Christ's dignity. For the fact that the father of a bishop pays
tithes to a priest does not hinder his son, the bishop, from being of
higher rank than an ordinary priest. Consequently, although we may
say that Christ paid tithes when Abraham paid them to Melchisedech,
it does not follow that Christ was not greater than Melchisedech.

_On the contrary,_ Augustine says (Gen. ad lit. x) that "Christ did
not pay tithes there," i.e. in Abraham, "for His flesh derived from
him, not the heat of the wound, but the matter of the antidote."

_I answer that,_ It behooves us to say that the sense of the passage
quoted from the Apostle is that Christ did not pay tithes in Abraham.
For the Apostle proves that the priesthood according to the order of
Melchisedech is greater than the Levitical priesthood, from the fact
that Abraham paid tithes to Melchisedech, while Levi, from whom the
legal priesthood was derived, was yet in his loins. Now, if Christ
had also paid tithes in Abraham, His priesthood would not have been
according to the order of Melchisedech, but of a lower order.
Consequently we must say that Christ did not pay tithes in Abraham's
loins, as Levi did.

For since he who pays a tithe keeps nine parts to himself, and
surrenders the tenth to another, inasmuch as the number ten is the
sign of perfection, as being, in a sort, the terminus of all numbers
which mount from one to ten, it follows that he who pays a tithe
bears witness to his own imperfection and to the perfection of
another. Now, to sin is due the imperfection of the human race, which
needs to be perfected by Him who cleanses from sin. But to heal from
sin belongs to Christ alone, for He is the "Lamb that taketh away the
sin of the world" (John 1:29), whose figure was Melchisedech, as the
Apostle proves (Heb. 7). Therefore by giving tithes to Melchisedech,
Abraham foreshadowed that he, as being conceived in sin, and all who
were to be his descendants in contr
