John Chrysostom
Catena Aurea · Matthäusevangelium 6
Take heed that ye do not your alms before men, to be seen of them: otherwise ye have no reward of your Father which is in Heaven.
Observe how He has begun as it were describing some beast hard to be discerned, and ready to steal upon him who is not greatly on his guard against it; it enters in secretly, and carries off insensibly all those things that are within.
