25. With Christians there must be, not merely natural human affection such as exists even among heathen, but ardent, fervent love; not the mere appearance of love, the smoke--false, hypocritical love, as Paul calls it (Rom 12, 9)--but real fervor and fire, which consent not to be easily extinguished, but which endure like the love between husband and wife, or the love of parents for children. True conjugal and parental love is not easily quenched, even though the object of its affection be weak, diseased or dangerously ill. Rather the greater the need and the danger of one individual, the more is the heart of the other moved and the brighter does love burn. 26. Such sincere love, as the apostle elsewhere styles it, must exist among Christians who are all children of one Father in heaven and brothers and sisters. Indeed, they are under obligation to love even their enemies--who are human beings of the same flesh and blood--and to wish no one evil but rather to serve all wherever possible. This love is the beautiful red robe for the adornment of Christians, supplementing the pure white garment of faith received in baptism. It is to be worn in obedience to the example of Christ, who for us, even while we were enemies, wore the same red garment of love when he was sprinkled with his own blood. It was then he burned with the intense fire of ineffable and most exalted love. 27. The apostles were moved to admonitions of this character because they clearly perceived the great weakness and imperfection bound to exist among Christians even in their outward lives. They knew that no one could, in his everyday life among men, live so discreetly as not at some time or other, by word, gesture or act, to give offense to someone, moving him to anger. Such perfection of life is found in no family, not even with husband and wife. The case is the same as in the human body: one member frequently comes in conflict with another; a man may inadvertently bite his tongue or scratch his face. He who would be a saint so stern and selfish as to endure no evil words or acts, and to excuse no imperfections, is unfit to dwell among men. He knows nothing of Christian love, and can neither believe nor put into practice the article of the Creed concerning the forgiveness of sins. 28. So the Christian's fire of love must be characterized, not by a dull, cold red, but by a warm scarlet--according to the Scriptures (Ex 26, 1), "Coccum bis tinctam" (rose-red). This love retains its fire and is really true, having which the Christian is not easily disheartened and overcome by wrath, impatience and revenge, but to a certain extent is able to endure and tolerate attacks upon himself calculated to distress. It manifests itself more strongly in suffering and enduring than in action.
