Excerpt: Declarations:
II. DECLARATION AND PROMISE
(M.P., number 7)
5. The declaration and promise by the Catholic, necessary for dispensation from the impediment to a mixed marriage (either mixed religion or disparity of worship), shall be made, in the following words or their substantial equivalent:
"I reaffirm my faith in Jesus Christ and, with God's help, intend to continue living that faith in the Catholic Church."
"I promise to do all in my power to share the faith I have received with our children by having them baptized and reared as Catholics."
6. The declaration and promise are made in the presence of a priest or deacon either orally or in writing as the Catholic prefers.
7. The form of the declaration and promise is not altered in the case of the marriage of a Catholic with another baptized Christian, but the priest should draw the attention of the Catholic to the communion of spiritual benefits in such a Christian marriage. The promise and declaration should be made in the light of the "certain, though imperfect, communion" of the non-Catholic with the Catholic Church because of the belief in Christ and baptism (cf. Decree on Ecumenism, number 3).
8. At an opportune time before marriage, and preferably as part of the usual pre-marital instructions, the non-Catholic must be informed of the promises and of the responsibility of the Catholic. No precise manner or occasion of informing the non-Catholic is prescribed. It may be done by the priest, deacon or the Catholic party. No formal statement of the non-Catholic is required. But the mutual understanding of this question beforehand should prevent possible disharmony that might otherwise arise during married life.
9. The priest who submits the request for dispensation from the impediment to a mixed marriage shall certify that the declaration and promise have been made by the Catholic and that the non- Catholic has been informed of this requirement. This is done in the following or similar words:
"The required promise and declaration have been made by the Catholic in my presence. The non-Catholic has been informed of this requirement so that it is certain that he (she) is aware of the promise and obligation on the part of the Catholic."
The promise of the Catholic must be sincerely made, and is to be presumed to be sincerely made. If, however, the priest has reason to doubt the sincerity of the promise made by the Catholic, he may not recommend the request for the dispensation and should submit the matter to the local Ordinary.
