Without these promises, the Church will not consent to a mixed marriage, and if the Church does not consent the marriage is unlawful. On the other hand, the Church shows its joy and approval at a true Catholic marriage by the Nuptial Mass and solemn ceremonies. The Church does not seek to make converts by its laws concerning mixed marriages, but seeks only to keep its children from losing their faith and becoming perverts by constant company with persons not Catholics. The Church does not wish persons to become Catholics merely for the sake of marrying Catholics. Such conversions are, as a rule, not sincere, do no good, but rather make such converts hypocrites and guilty of greater sins, especially sins of sacrilege.
Many marriages prove unhappy because they are entered into hastily and without worthy motives.
A. Marriages are entered into hastily when persons do not sufficiently consider and investigate the character, habits and dispositions of the one they intend to marry. It is wise to look for lasting qualities and solid virtues in a life-long companion and not to be carried away with characteristics that please only for a time. A. Motives for marriage are worthy when persons enter it for the sake of doing God's will and fulfilling the end for which He instituted the Sacrament. Whatever is opposed to the true object of the Sacrament and the sanctification of the husband and wife must be an unworthy motive. A. Parents may be guilty of great injustice to their children in case of marriage by seeking the gratification of their own aims and desires, rather than the good of their children, and thus for selfish and unreasonable motives forcing their children to marry persons they dislike or preventing them from marrying the persons chosen by the dictates of their conscience, or compelling them to marry when they have no vocation for such a life or no true knowledge of its obligations.
