“I thoroughly disagree (with Rubio’s opposition to gay marriage), being raised in a Catholic family... the Baltimore catechism, to get back to our hometown of Baltimore, was what we were raised on. And I think that this statement by Senator Rubio is most unfortunate. It’s a polarizing statement. The fact is, is that what we’re taught was to respect people in our faith and to say that this endangers mainstream Christian thinking is so completely wrong.”So, she says we should look at the Baltimore Catechism. Fortunately, it's online, and I looked up the section on matrimony. It says [emphasis mine]:
Q. 1005. What is the Sacrament of Matrimony?A. The Sacrament of Matrimony is the Sacrament which unites a Christian man and woman in lawful marriage.
Q. 1006. When are persons lawfully married?A. Persons are lawfully married when they comply with all the laws of God and of the Church relating to marriage. To marry unlawfully is a mortal sin, and it deprives the souls of the grace of the Sacrament.
