Chapter IV. Banns of Marriage
Before publishing the banns of marriage the priest who has the cure of souls must have at least a general knowledge of those who wish to marry. The Ritual prescribes that he should inquire whether there is between them any impediment of kindred or affinity, or any other; whether they wish to marry freely and of their own accord; whether they be of age, and know the rudiments of the Faith so as to be able to teach it to their children (Can. 1020).
With regard to people with no fixed abode, strangers, the wives of soldiers, sailors, and others, who are said to have died in foreign parts, the Ritual admonishes the priest not to admit them readily to marriage before making all needful inquiries about them, and referring their case to the bishop, so as to have his leave for the marriage. Canon 10211 prescribes that the parish priest demand the certificate of baptism of the parties unless they were baptized in his parish, and their reception of Confirmation, as far as possible.

If no impediment has been discovered by examining the parties, the priest publishes the banns in accordance with the decree of the Council of Trent.1 “ It ordains that for the future before a marriage is contracted the proper parish priest of the contracting parties shall three times announce publicly in the Church, during the solemnization of Mass, on three continuous festival days, between whom marriage is to be celebrated; after which publication of banns, if there be no lawful impediment opposed, the marriage shall be proceeded with, in the face of the Church.”
The reasons for this law are: the avoidance of clandestine marriages, so that it being known who are married, there may be less danger of bigamous marriages; the discovery of impediments of marriage; and the protection of the rights of others arising from former betrothal. The banns must be published by the parish priest in the church of the parish or district where the parties have their domicile or quasi-domicile, If they live in different parishes, the banns must be published in both; and if either or both have lived six months in another place after the age of puberty, the parish priest should inform the bishop, who will prescribe what is to be done (Can. 1023). They must be published during the principal Mass on three successive days of obligation; but if the publication has been omitted at Mass, the omission may be made good in the evening if there be a considerable concourse of people at the evening service.

The very form which is commonly made use of in publishing banns shows that by them the Church intends to impose a serious obligation on all who know of any impediment between the parties who wish to marry to communicate their knowledge to the parish priest. This precept of the Church will bind even when the impediment is matter of a natural or promised secret, for such a secret cannot avail against the just commands of a superior. A professional secret binds more strictly, but it does not excuse one who knows it from doing what he can without betraying the secret to procure the removal of the impediment.
p. ii, 198
The obligation of publishing banns is a serious one, but for good reason the bishop or his Vicar-General may dispense with them either wholly or in part. According to approved theologians, the bishop is even obliged sometimes to dispense with banns, when charity toward his flock requires it. Thus a dispensation should be given when it is probable that otherwise the marriage will be maliciously prevented, when it is a necessary means to preserve the reputation of the parties who. are thought to be man and wife already, and when the parties are obliged to depart at once to foreign countries. For lighter reasons the bishop may dispense, but he is not obliged to do so.
A parish priest has no jurisdiction in the external forum, and so he cannot dispense of his own authority from banns. In some special case, however, it might be necessary to marry the parties without delay, and then if there were no time to have recourse to the bishop, a simple priest might declare that under the circumstances the law with regard to banns ceased to be of obligation.
Sec. 1. According to Canon 1031, when a doubt has arisen about the existence of an impediment between the parties— (1) The parish priest should investigate the matter more carefully, interrogating at least two witnesses under oath, who are worthy of credence, provided that there is no question of an impediment from the knowledge of which the reputation of the parties will suffer, and interrogating also the parties themselves if it be necessary.
(2) Let him proceed with or finish the publication of the banns if the doubt arose before they were begun or before they were finished.
(3) Let him not assist at the marriage without consulting the Ordinary if he prudently judge that the doubt still remains.
Sec. ii. When a certain impediment has been discovered— (1) If the impediment be secret, let the parish priest proceed with and finish the banns, and without mentioning names let him report the matter to the local Ordinary or to the Sacred Penitentiary.
(2) If it is public and is discovered before the publication of the banns is begun, let the parish priest not proceed further until the impediment is removed, although he may know that a dispensation has been obtained only for the forum of conscience; if it is discovered after the first or second publication of banns, let the parish priest finish the banns and report the matter to the Ordinary.
Sec. iii. Finally, if no impediment, doubtful or certain, has been discovered, let the parish priest, after the banns are published, admit the parties to the celebration of marriage.
Canon 1030 lays it down that this should not be done until the parish priest has received all the necessary documents and three days have elapsed after the last publication of the banns, unless there be some good reason to the contrary.
Canon 1026 forbids banns to be published of a marriage which is contracted by dispensation from the impediment of mixed religion or difference of worship, unless the local Ordinary deems it proper to permit them with prudence and the removal of scandal, provided that the apostolic dispensation has been granted and no mention be made of the religion of the non-Catholic party.
The Ritual prescribes that the parties should be diligently instructed how they should live in a pious and Christian way in the state of wedlock. This is done partly in the confessional, partly outside. The parish priest may make a brief discourse to them at the end of the ceremony, or if he prefer he may read to them the instruction which is inserted in the Ritual for the purpose (Can. 1033).
Canon 1034 bids parish priests seriously to warn minors not to contract marriage without the knowledge of their parents or against their reasonable wish. In case of disobedience parish priests should not assist at the marriage without consulting the local Ordinary.
