O blessed Church of ours, which the honor of the divine condescension illuminates, which in our own times the glorious blood of martyrs renders illustrious! She was white before in the works of the brethren; now she has become purple in the blood of the martyrs. Among her flowers are wanting neither roses nor lilies. Now let each one strive for the largest dignity of either honor. Let them receive crowns, either white, as of labors, or of purple, as of suffering. In the heavenly camp both peace and strife have their own flowers, with which the soldier of Christ may be crowned for glory. I bid you, most brave and beloved brethren, always heartily farewell in the Lord; and have me in remembrance. Fare ye well.
St. Cyprian of Carthage, EPISTLE 8, ANF 8, pp.287-289
