In your patience possess ye your souls. Patience, therefore, is the possession of our souls. Firstly, because patience rules the soul and directs it in peace, and bends and influences it as it pleases. Secondly, because no one can keep the hope of a future life, as S. Augustine says, unless he have patience in the labours of the present one. Thirdly, S. Gregory (Homily xxxv. in Evangel.): "The possession of the soul consists of the virtue of patience, because patience is the root and guardian of all virtues. Through patience, we possess our souls, because, while we learn to govern ourselves, we begin to possess the knowledge that we are (quod sumus, quod adverb). It is patience to endure calmly the evils we suffer from others, and to be affected with no painful feeling against him who inflicts them upon us. For whoever so takes the oppressions of others, as to grieve in silence, but to look out for a time of retribution, does not possess this virtue, but only makes a show of it. Again, Solomon says, Proverbs 16:32: "The patient man is better than the valiant, and he that ruleth his spirit than he that taketh cities." The taking of a city is therefore a less victory, because the conquest is outside ourselves. That which is subdued by patience is greater, because the mind is subdued by itself, and subjects itself to itself when patience subdues it to the humility of endurance." S. Gregory adds the example of the Abbot Stephen, who returned contumelies with thanks, and thought a gain, loss, and considered his adversaries his helpers. Hence, at his death, angels were seen taking his soul to heaven.
The impatient do not possess their souls, but are possessed by the vices of wrath and vindictiveness, and consequently by Satan. They, only, who have ardent love can gain true patience, as those fervent martyrs—SS. Ignatius, Laurence, Sebastian, Vincent, and others. Trajan the Emperor, consequently, said when he conferred, by his sentence, martyrdom on S. Ignatius, "No people suffer so much for their God as the Christians." S. Gregory (book v. Moral. chap13), "What is it to possess our souls, but to live perfectly in all things, and to govern all the emotions of our minds by the art of virtue? Whoever therefore possesses patience, possesses his soul, because he is thus made strong against all adversities, so that he rules even by subduing himself. By whatever he masters himself, he clearly shows himself unmastered, for when he masters himself in his pleasures, he prepares himself to be unmastered by their opposites." In his39th Epistle to Theoclister; "In your patience possess your souls. Consider a moment where patience would be if there were nothing to be endured. I suspect that he would not be an Abel who had no Cain. For if the good were without misfortunes, they could not be perfectly good, for they would have no purgation. Their very society with evil is the purification of the good." Hence, says Theodore Studita in his19th Catechetical Lecture, "Endurance is the highest perfection of virtue;" and Lucan (lib. ix.):
—Serpens, sitis, ardor, arenæ
Dulcia Virtutis, gaudet Patientia duris.
The sandy desert"s burning heat; the pangs
Of raging thirst; its serpent"s cruel fangs,
Are Virtue"s sweets; for Patience joys in these,
And welcomes hardships more than softest case.
Lastly, the whole band of virtues flows into patience, so that it appears to be the complex of all virtues. Sencea ( Ephesians 69. and following): "There is i fortitude of which the brands are patience, endurance, and toleration. There is prudence, without which no undertaking is entered upon, and which persuades us to endure bravely what we cannot escape. There is constancy which cannot be cast down from its pedestal, and the determination of which no force can overthrow. Here is that indivisible society of virtues." And see the words of S. James 1:4.
