On sins of the brethren

A brother asked Abba Poemen, "If I see my brother sin, is it right to say nothing about it?"  The old man replied, "Whenever we cover our brother's sin, God will cover ours; whenever we tell people about our brother's guilt, God will do the same about ours.

No greater love than this

There is no greater love than that a man lays down his life for his neighbor.  When you hear someone complaining and you struggle with yourself and do not answer him back with complaints; when you are hurt and bear it patiently, not looking for revenge; then you are laying down your life for your neighbor.
