Cyprian Patristic
c. A.D. 200–258
“For what could happen to me more desirable and more joyful than to be now close to you, that you might embrace me with those hands, which, pure and innocent, and maintaining the faith of the Lord, have rejected the profane obedience? What more pleasant and sublime than now to kiss your lips, which with a glorious voice have confessed the Lord, to be looked upon even in presence by your eyes, which, despising the world, have become worthy”

“It is remarkable how he left no one without consolation, but said to each one what was needed! They "exhorted" them to endure all things courageously. Therefore, he says, I did not seek glory. Above, the apostle likened himself to a nurse; now he likens himself to a father, showing his love, his authority, and his simplicity. For what father conducts himself proudly before his children? To exhort (in the Slavonic text – "to testify") – this is already a sign of very strict instruction. Therefore, I, he says, did not flatter. After saying "as a father," he added also the word "exhorted" ("testifying"). For not strictly, he says, but as fathers (testifying) "to walk worthy of God." See how, in recounting what happened before, he both teaches and persuades. For if God calls us into the Kingdom, then we must endure all things.”

“And what were you told? To lead a life worthy of God, that is, that your conduct should be such that it might reflect favorably on the ministers of Christ. "To lead a life worthy of the Lord, fully pleasing to him" (Col. 1:10). Who calls you into his own kingdom and glory, as is evident also in "Honor wisdom, that you may reign for ever" (Wis. 6:21).”
