What can anyone do to you by word or injury? He hurts himself rather than you, and no matter who he may be he cannot escape the judgment of God. Keep God before your eyes, therefore…
THE VAIN JUDGMENTS OF MEN
The voice of Christ tells us… My Child, trust firmly in the Lord, and do not fear the judgment of men when conscience tells you that you are upright and innocent. For it is good and blessed to suffer such things, and they will not weigh heavily on the humble heart that trusts in God rather than in itself. Many men say many things, and therefore little faith is to be put in them.
Likewise, it is impossible to satisfy all men. Although St Paul tried to please all in the Lord, and became all things to men, yet he made little of their opinions. He laboured abundantly for the edification and salvation of others, as much as lay in him and as much as he could, but he could not escape being sometimes judged and despised by others. Therefore, he committed all to God Who knows all things, and defended himself by his patience and humility against the tongues of those who spoke unjustly or thought foolish things and lies, or made accusations against him. Sometimes, indeed, he did answer them, but only lest his silence scandalise the weak.
Today he is here, tomorrow he is not seen
Who are you, then, that you should be afraid of mortal man? Today he is here, tomorrow he is not seen. Fear God and you will not be afraid of the terrors of men. What can anyone do to you by word or injury? He hurts himself rather than you, and no matter who he may be he cannot escape the judgment of God. Keep God before your eyes, therefore, and do not quarrel with peevish words.
If it seems, then, that you are worsted and that you suffer undeserved shame, do not repine over it and do not lessen your crown by impatience. Look instead to heaven, to Me, Who have power to deliver you from all disgrace and injury, and to render to everyone according to his works.
