Be Watchful Over Yourself
So, brother, since the enemy watches you constantly, waiting for an opportunity to sow evil in you, be doubly watchful over yourself, lest you fall into the nets spread for you. As soon as he shows you some fault in your neighbour, hasten to repel this thought, lest it take root in you and grow. Cast it out, so that no trace is left in you, and replace it by the thought of the good qualities you know your neighbour to possess, or of those people generally should have.
If you still feel the impulse to pass judgment, add to this the truth, that you are given no authority for this and that the moment you assume this authority you thereby make yourself worthy of judgment and condemnation, not before powerless men, but before God, the all-powerful Judge of all.
- St. Nicodemus the Hagiorite
