This locked thread, in response to whether a Catholic can marry a Methodist outside the Catholic church:
“For a Catholic to marry outside of the Catholic Church is a sin and the Church does not consider such a marriage to be valid. Further, since the marriage is not considered to be valid, marital relations are considered to be gravely sinful.”
I don’t see how this can be correct when the Catholic Diocese of Dallas on the website for its marriage tribunal has a large online pamphlet devoted to discussing marriages between Catholics and non-Catholics. See here:
This addresses mixed marriages, and refers to obtaining permission to enter into a mixed marriage from the local bishop, as well as explaining how to obtain a dispensation from the canonical form to be validly and licitly married to a non-Catholic Christian in a ceremony outside the Catholic Church, citing to, among other cites, Pope Paul VI, Apostolic Letter Matrimonia Mixta, March 31, 1970. My understanding is that even the Council of Trent recognized mixed marriages so long as the spouses vowed to raise the children Catholic. Today, such a vow is not necessary, rather the Catholic spouse must promise as follows:
"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.”
Catholics can even marry non-Christians with permission of the bishop to enter into a marriage with disparity of cult.
In sum, this answer appears very wrong and other threads link to this answer. This seems highly misleading. Can anyone clear this up?
