Catena Aurea · Matthäusevangelium 16
Then said Jesus unto his disciples, If any man will come after me, let him deny himself, and take up his cross, and follow me. For whosoever will save his life shall lose it: and whosoever will lose his life for my sake shall find it.
(Hom. in Ev. xxxii. 3.) There are two ways of taking our cross; when the body is afflicted by abstinence, or when the heart is pained by compassion for another. Forasmuch as our very virtues are beset with faults, we must declare that vainglory sometimes attends abstinence of flesh, for the emaciated body and pale countenance betray this high virtue to the praise of the world. Compassion again is sometimes attended by a false affection, which is hereby led to be consenting unto sin; to shut out these, He adds, and follow me.
