At first view it may seem a solecism to speak of the condition of parentality as one which a man can have need to be invested with. The reason is, that it is not common for any ceremony to be required as necessary to man's being deemed in law the father of such or such a child. But the institution of such ceremony, whether advisable or not, is at least perfectly conceivable. Nor are there wanting cases in which it has actually been exemplified. By an article in the Roman law, adopted by many modern nations, an illegitimate child is rendered legitimate by the subsequent marriage of his parents. If then a priest, or other person whose office it was were to refuse to join a man and woman in matrimony, such refusal, besides being a wrongful non-investment with respect to the two matrimonial conditions, would be a wrongful non-investment of parentality and filiation, to the prejudice of any children who should have been legitimated.
