The fact that she is a Mormon does not hinder the possibility of marriage. You would need a dispensation for disparity of worship. The baptism of Mormons is not recognised as a valid Christian baptism by the Catholic Church. The following must be completed for the permission of mixed religious marriage and/or the dispensation from the disparity of a cult to be granted. Both parties must say - "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 baptised and reared as Catholic" ---------------------- "The reasons given by the Catholic Church The baptism of the Mormons is not recognised as a valid baptism for a number of reasons. One of those reasons concerns the Mormon definition of the Trinity. In the administration of the Sacrament of Baptism, a specific formula must be used as commanded by the Fourth Lateran Council. Those words are. "Being commissioned by Jesus Christ, I baptize you in the name of the Father, and of the Son, and of the Holy Spirit." The formula applied by the Mormons might appear to be a Trinitarian formula. But in reality, while the formula of the Mormons is similar to the formula of the Catholic faith, there is no fundamental doctrinal agreement in its application. The Mormon invocation of the Trinity is not a true invocation of the Trinity because the Father, the Son, and the Holy Spirit, according to them, are not three persons in which subsists the one Godhead, but three gods who form one divinity. The Mormons believe that the divinity originated when three gods decided to unite and form the divinity in order to bring about human salvation. Furthermore, the Mormons believe that God the Father is an exalted man, a native from another planet, who has acquired his divine status through a death similar to that of human beings, this being a necessary way of becoming divine. God the Father has relatives and this is explained by the doctrine of infinite regression of the gods who initially were mortal. God the Father has a wife, the Heavenly Mother, with whom he shared the responsibility of creation. They procreated sons in the spiritual world. Their firstborn was Jesus Christ, equal to all men, who acquired his divinity in a pre-mortal existence. Even the Holy Spirit was the son of heavenly parents. The Son and the Holy Spirit were procreated after the beginning of the creation of the world known to mankind. Four gods were directly responsible for the universe, three of whom established a covenant and therefore formed the divinity. As can be appreciated, the Mormon baptism does not in any way contain the doctrinal belief that is associated with the Christian doctrine of the Trinity. The words, "Father, Son and Holy Spirit," have for the Mormons, a totally different meaning than that of the Christian faiths. While this is only one reason, that being sufficient to affirm that the Mormon baptism is not valid, there are other reasons. Over and above the Mormon belief that there is no real Trinity, the Mormons do not believe in original sin, nor that Christ instituted baptism. Based on this, those who believe that they were baptized in the Mormon religion, must be baptized in the Catholic faith upon their conversion because they were never validly baptized as commanded by Jesus and taught by the Catholic faith. This conclusion was handed down to the Catholic Church by The Congregation for the Doctrine of the Faith in July, 2001. http://www.catholicdoors.com/faq/qu46.htm#answer1

Alatea answered this Q from the Catholic viewpoint. From the Mormon viewpoint, the answer is that the Church recognizes any marriage that is considered 'legal' in the land in which the ceremony is conducted. Thereafter, they would not be considered to be 'living in sin', you might say. HOWEVER, the aim of Latter-day Saints ["Mormons"] is to receive eternal life - or God's life - which Mormons believe means living in Heaven with your wife and family as a united family Forever. To achieve this, one must not only endeavour to keep all the commandments of God, but to marry in the House of God Forever. This means marrying by proper authority from God in a true Temple of God. Marriages which are conducted in the Temple mean Forever Marriages and Forever Families. This is what we aim for. So a Mormon could marry a Catholic - yes; but unless that person converted to the LDS Church, they could not go together to the temple as a couple, and therefore, could not marry Forever. They would literally marry "... til death do you part."

I am a mormon and I am getting married in a catholic church this august. As along as you are baptized and have not previously been married you can be joined in a catholic ceremony barring the rite of catholic communion.

Yes. The Catholic Church allows marriage between Catholics and non-Catholics. Because the Church recognizes the tremendous challenge that the interfaith couple will face, they may have to get permission from the bishop.
