Obstacles to Marriage
Obstacles to Marriage.—Since marriage is a most important contract and a Sacrament, it is necessary to ascertain beforehand with moral certainty that there is no obstacle to its valid and lawful celebration. This imposes duties on the pastor, the couple themselves, and the faithful who know them.
(a) The pastor in virtue of his office is gravely obliged to make inquiries about the competency and fitness of the prospective husband and wife, and even in a death-bed marriage the obligation does not cease. Church law prescribes the method of inquiry, which should include an examination and instruction of the couple and a publication of the marriage. Of course, there is an obligation of confidential secrecy.
(b) The couple are bound to present themselves to the pastor within a reasonable time before the marriage in order to make these arrangements, and should bring with them the necessary papers (for example, their baptismal certificates, license to marry, testimonials). They are gravely obliged to make known either to the pastor or to the confessor any impediment, even though it be of a secret and culpable nature, in order that their marriage may be valid and lawful, unless they wish to give up the marriage or seek a dispensation in some other way.
(c) The people who know of an impediment to a marriage are bound under pain of mortal sin to make it known in time to the pastor or Ordinary; for the natural and divine laws, as well as the law of the Church, hold one to speak when this will prevent irreverence to the Sacrament of Matrimony, sin and other serious evils to the neighbor. The obligation ceases, however, when the revelation is either impossible or useless. Cases of impossibility are those in which revelation will cause great spiritual harm (e.g., public scandal), or great temporal harm of a public kind (e.g., violation of professional secret), or a great temporal harm of a private kind (e.g., persecution), unless a more serious evil will result from concealment. Revelation is useless when the marriage can be stopped or made legal in some other way (e.g., by persuading the couple to break their engagement or get a dispensation), or when one foresees that the revelation will have no effect.
