83. Now this comparison seems to be not
unfitly brought forward in this place, since the kingdom of heaven is
redemption from sin, and therefore we all, both bad and good, are
mingled with the meal of the Church that we all may be a new
lump. But that no one may be afraid that an admixture of evil
leaven might injure the lump, the Apostle said: “That ye
may be a new lump, even as ye are unleavened;” 1 Cor. v. 7. that is to say, This mixture will
render you again such, as in the pure integrity of your
innocence. If we thus have compassion, we are not stained with
the sins of others, but we gain the restoration of another to the
increase of our own grace, so that our integrity remains as it
was. And therefore he adds: “For Christ our Passover
is sacrificed for us; ” 1 Cor. v. 7. that is, the
Passion of the Lord profited all, and gave redemption to sinners who
repented of the sins they had committed.
