Pseudo-Chrysostom
Catena Aurea · Matthäusevangelium 6
Therefore when thou doest thine alms, do not sound a trumpet before thee, as the hypocrites do in the synagogues and in the streets, that they may have glory of men. Verily I say unto you, They have their reward. But when thou doest alms, let not thy left hand know what thy right hand doeth: That thine alms may be in secret: and thy Father which seeth in secret Himself shall reward thee openly.
(Hom. xv.) He opposes three chief virtues, alms, prayer, and fasting, to three evil things against which the Lord undertook the war of temptation. For He fought for us in the wilderness against gluttony; against covetousness on the mount; against false glory on the temple. It is alms that scatter abroad against covetousness which heaps up; fasting against gluttony which is its contrary; prayer against false glory, seeing that all other evil things come out of evil, this alone comes out of good; and therefore it is not overthrown but rather nourished of good, and has no remedy that may avail against it but prayer only.
