Should Marriage for Same Sex Couples be Legal?

Philosophical Catholic view point

On a philosophical viewpoint here is why homosexuality is seen Biblically as wrong. Under the strict beliefs of the Catholic church, the followers of the Catholic Church believe that homosexuality is wrong. This argument would be valid to an audience who takes a firm stance on religious beliefs. Biblically speaking Gen. 2:24 is the only text which makes it clear that marriage, as intended by God, is for a male and a female. All other passages either alluding or referring to this are commentary in one form or another and presume heterosexuality as the gender basis for marriage in God's plan. For example, Matt 5:27-32; Matt 19:1-9; there are parallel passages in Mark and Luke; Ephesians 5:21-33. When the prophets (especially Hosea) use marriage as a metaphor or symbol to describe God's relationship with Israel, the heterosexuality of marriage is presumed.

In his commentary on Romans 1:26b-27, Brendan Byrne writes: "With respect to both female and male homosexual practice, the text points to an 'exchange' of the 'natural' form of (sexual) relations for that which is 'contrary to nature'. The language reflects the conventional Stoic sense of 'nature' as the established order of things. Central to that established order was dominance of male over female as far as gender relationships were concerned. Where ancient writers condemned same-sex relations, what they found offensive was the fact that such relations blurred the all-important distinction of gender role, inducing males to act as females and vice versa. The 'reduction' of the male to the female constituted a 'shame' contrary to nature. In the Jewish adaptation of such ideas reflected in this text a more theological note may also be present: such behavior is contrary to the design inserted into the natural order by the Creator."

Byrne mentions in a subsequent paragraph that the Letter to the Romans and the world then made no distinction between a homosexual orientation and the free choice made by some individuals to engage in homosexual genital relations. So we shall not find in Scripture any commentary on the orientation of homosexuality itself; just homosexual genital acts.

There is also 1 Timothy 1:10 which refers to male homosexuality.

Here is a link to a section in the Catechism of the Catholic Church (CCC) on homosexuality: http://www.scborromeo.org/ccc/p3s2c2a6.htm #2357. The Catechism is a book in the Catholic religion that explains the beliefs of the Catholic Church. In the Catholic Catechism, homosexuality is forbidden. The teachings of the Catholic Church as laid out in the revised version of the Catechism of the Catholic Church, in particular the teachings on sexuality: "All the baptized are called to chastity" (CCC, n.2348); "Married people are called to live conjugal chastity; others practice chastity in continence" (CCC, n.2349); "... tradition has always declared that homosexual acts are intrinsically disordered... Under no circumstance can they be approved" (CCC, n.2333); This means that under certain religious beliefs homosexuality is seen as a disorder.
I believe that homosexuals should not be able to marry because God created male and female to become one flesh despite their opposite genders. The genitals of both man and woman were made specifically for each other, and it is in God’s creation that he made them that way for a specific reason: procreation. Man and woman are supposed to populate the earth and beget children. Man and woman cleave to each other to become one, and that is a very spiritual thing to many religious people. Catholics believe that sexuality was designed by God as a sign of the love of Christ, the bridegroom, for his Bride, the Church, and therefore sexual activity is appropriate only in marriage. Catholic teaching holds that: “Sexuality is ordered to the conjugal love of man and woman. In marriage the physical intimacy of the spouses becomes a sign and pledge of spiritual communion.” (CCC, n.2360)
