Mark 2:8

(ubi sup.) Who remits sin by those also to whom He has assigned the power of remitting, and therefore Christ is proved to be very God, for He is able to remit sins as God. The Jews then are in error, who although they hold the Christ both to be God, and to be able to remit sins, do not however believe that Jesus is the Christ. But the Arians err much more madly, who although overwhelmed with the words of the Evangelist, so that they cannot deny that Jesus is the Christ, and can remit sin, nevertheless fear not to deny that He is God. But He Himself, desiring to shame the traitors both by His knowledge of things hidden and by the virtue of His works, manifests Himself to be God. For there follows: And immediately when Jesus perceived in his spirit that they so reasoned, he said unto them, Why reason ye these things in your hearts? In which He shows Himself to be God, since He can know the hidden things of the heart; and in a manner though silent He speaks thus, With the same power and majesty, by which I look upon your thoughts, I can forgive the sins of men.

(non occ.) Further, He first healed by the remission of sins that which He had come to seek, that is, a soul, so that when they faithlessly doubted, then He might bring forward a work before them, and in this way His word might be confirmed by the work, and a hidden sign be proved by an open one, that is, the health of the soul by the healing of the body.
