The consent by which the spouses mutually give and receive one another is sealed by God himself.141 From their covenant arises "an institution, confirmed by the divine law, . . . even in the eyes of society." The covenant between the spouses is integrated into God's covenant with man: "Authentic married love is caught up into divine love." (CCC 1639)
If you are Catholic and were married in a non-Catholic ceremony (e.g. before a justice of the peace, minister, rabbi, etc.) and are now seeking to be married in the Church? Then you are likely seeking a Convalidation.
"The Church very much wants to assist these couples who later want to enter into valid Catholic marriage, and it offers them pastoral and spiritual support as they need it. When these couples are ready and free to do so, they celebrate what is called a convalidation, from the Latin word meaning “to firm up” or “to strengthen.”
"It is important to realize that a convalidation is not merely a renewal of vows made previously but is a new act of consent by each spouse. This new act of consent is essential to marriage, and the words that the couple expresses are the outward sign of the gift of self that they exchange. This convalidation of marriage may be celebrated within Mass or outside of Mass, again depending on the particular situation of the couple. If both are Catholic, it is fitting that the convalidation be celebrated within Mass. If one spouse is not, it is preferable that it be celebrated outside of Mass." - from Together for Life Online - Find out more HERE
