1 Cyprian to the presbyters and deacons, and to the whole people, his brethren in the Lord, greeting. The divine benefits, beloved brethren, should be acknowledged and embraced, wherewith the Lord has condescended to embellish and illustrate His Church in our times by granting a respite to His good confessors and His glorious martyrs, that they who had grandly confessed Christ should afterwards adorn Christ's clergy in ecclesiastical ministries. Exult, therefore, and rejoice with me on receiving my letter, wherein I and my colleagues who were then present mention to you Celerinus, our brother, glorious alike for his courage and his character, as added to our clergy, not by human recommendation, but by divine condescension; who, when he hesitated to yield to the Church, was constrained by her own admonition and exhortation, in a vision by night, not to refuse our persuasions; and she had more power, and constrained him, because it was not right, nor was it becoming, that he should be without ecclesiastical honour, whom the Lord honoured with the dignity of heavenly glory.
