Section 15 revoked the automatic "latae sententiae" excommunication imposed by the 1917 Code of Canon Law for marrying before a non-Catholic minister or for failing to secure the Catholic upbringing of the children. The 1970 apostolic letter made the granting of a dispensation by the Ordinary conditional on a promise by the Catholic spouse to remove all danger of defecting from the faith and to do all that he or she can to have all the children baptized and brought up in the Catholic Church. The non-Catholic partner was to be made aware of these promises made by the Catholic spouse (sections 4 and 5).
