VI. Christian love demands self-denial not self-seeking.
In thus writing to you, brother, I exhort and admonish you in the Lord, laying aside all ambitious desires to cherish rather a spirit of love and to adorn yourself to your profit with the virtues of love, according to the Apostle's teaching. For love “is patient and kind, and envies not, acts not iniquitously, is not puffed up, is not ambitious, seeks not its own.” Hence if love seeks not its own, how greatly does he sin who covets another's? From which I desire you to keep yourself altogether, and to remember that sentence which says, “Hold what you have, that no other take your crown.” For if you seek what is not permitted, you will deprive yourself by your own action and judgment of the peace of the universal Church. Our brother and fellow bishop Lucian and our son Basil the deacon, attended to your injunctions with all the zeal they possessed, but justice refused to give effect to their pleadings. Dated the 22nd of May in the consulship of the illustrious Herculanus (452).
