13. But when anyone yieldeth to a second marriage, he giveth up this unity, and the signification of this third sacrament does not hold in his case: wherefore marriage should not advance beyond _one_, because such advance cannot signify unity. Besides, by a second marriage he departeth from the union of his former marriage: but the Church ever since she hath united herself to Christ, hath never departed from Him, neither hath Christ ever departed from her. Wherefore one who hath twice married cannot signify such an unity. Whence also deservedly from the defect of this sacramental signification marriage cannot be repeated. 14. Note also this, that according to the statute of the Council of Carthage the bridegroom and bride are to be presented by the parents or bridesmen unto the priest in order to be blessed. And having received the blessing, out of reverence to it, they do not consummate the marriage till the next day. 15. Again by the appointment of Pope Evaristus marriages are to be blessed by the priest not without prayers and offerings. However, a man and woman who contract a second marriage must not be blessed by the priest, since, they having been already blessed, the ceremony may not be repeated. Nor ought marriages to be blessed unless both parties are still unmarried, for the reason given in the preface to the second book. [Footnote 556] [Footnote 556: It is laid down that a _widow_ on taking the vows is not veiled by the bishop, as is the case with a virgin. 'A priest,' Durandus continues, 'is prohibited from taking a part in second marriages and from giving the benediction to such as are twice married. But a widow taking the vows is married as it were twice, first to her late husband, and secondly unto Christ in her profession, wherefore the veil of consecration, or even of profession, is not given unto her, but she herself takes it from the altar. . . . Yet in the Pontifical, according to the Roman Order, we find the benediction of a widow professing continence, and also of her veil. For the Lord also comforted the widow of Serepta by the hand of Elias the prophet. And I have myself seen in the city (Rome, of course) the [Cardinal] Bishop of Ostia bless two widows among the virgins who took the vows' (Proem. II, c. 47).] {159}
