10. But let us pass over the question of whether permission to contract a marriage before the legal age, when craft supplies for age, is properly called a dispensation or rather has the force of a declaration, and therefore whether it ought to be classified as an act of grace or of justice. When one of the contracting parties or both are infected with heresy, and this is not mentioned in the application and could not be known in any other way, the apostolic letters granted in this matter lack those words and conditions which are customarily added to other dispensations. Let us see nevertheless whether others of equal force are present by which the executor of such letters should abstain from executing them. There can be no doubt about this, however, if we refer to what was required of the executor in such letters, "that he inform himself diligently about the premises" and see "whether it is really and legitimately obvious in such a minor that craft does supply for the defect in age". The same executor is commissioned to permit the applicant to marry "provided there is no other canonical impediment to contracting matrimony with a person legally free to marry, or with a person to whom an Apostolic dispensation has been granted, according to the norms of the Council of Trent". These words surely indicate that he should be no means permit a minor to enjoy such a dispensation or declaration if he learns that the minor was planning to marry a heretic.
