Council of Trent: Session 24
Chapter 6
Punishments inflicted on Abductors.
The holy Synod ordains, that no marriage can subsist between the abducer and her who is abducted, so long as she shall remain in the power of the abducer. But if she that has been abducted, being separated from the abducer, and being in a safe and free place, shall consent to have him for her husband, the abducer may have her for his wife; but nevertheless the abducer himself and all who lent him advice, aid, and countenance, shall be ipso jure excommunicated, for ever infamous, and incapable of all dignities; and if they be clerics they shall forfeit their rank. The abducer shall furthermore be bound, whether he marry the person abducted, or marry her not, to settle on her a handsome dowry at the discretion of the judge.
Chapter 7
Vagrants are to be married with caution.
There are many persons who are vagrants, having no settled homes; and, being of a profligate character, they, after abandoning their first wife, marry another, and very often several in different places, during the life-time of the first. The holy Synod, being desirous to obviate this disorder, gives this fatherly admonition to all whom it may concern, not easily to admit this class of vagrants to marriage; and It also exhorts the civil magistrates to punish such persons severely. But It commands parish priests not to be present at the marriages of such persons, unless they have first made a careful inquiry, and, having reported the circumstance to the Ordinary, they shall have obtained permission from him for so doing.
Chapter 8
Concubinage is severely punished.
It is a grievous sin for unmarried men to have concubines; but it is a most grievous sin, and one committed in special contempt of this great sacrament, for married men also to live in this state of damnation, and to have the audacity at times to maintain and keep them at their own homes even with their own wives. Wherefore, the holy Synod, that it may by suitable remedies provide against this exceeding evil, ordains that these concubinaries, whether unmarried or married, of whatsoever state, dignity, and condition they may be, if, after having been three times admonished on this subject by the Ordinary, even ex officio, they shall not have put away their concubines, and have separated themselves from all connexion with them, they shall be smitten with excommunication; from which they shall not be absolved until they have really obeyed the admonition given them. But if, regardless of this censure, they shall continue in concubinage during a year, they shall be proceeded against with severity by the Ordinary, according to the character of the crime. Women, whether married or single, who publicly live with adulterers or with concubinaries, if, after having been three times admonished, they shall not obey, shall be rigorously punished, according to the measure of their guilt, by the Ordinaries of the places, ex officio, even though not called upon to do so by any one; and they shall be cast forth from the city or diocese, if the Ordinaries shall think fit, calling in the aid of the Secular arm, if need be; the other penalties inflicted on adulterers and concubinaries remaining in their full force.
