The same rights as straight people, in the UK they can now have civil unions and I believe that it is fair.
People bring in the religious aspect of weddings but the majority of people get married in registry offices because it is cheaper, quicker and they like the smaller occasion. Or they don't even go to church and feel a church wedding will be hypocritical. I find it very rude and ignorant when fundie Christians don't recognise marriage if it is not in church. As someone who comes from a family that last saw a church wedding in 1967, I don't appreciate my family's choices being judged like that. I get very annoyed when people insist living together is not a true commitment and invalid. (I got these comments in Charismatic Churches, never the Catholic Church.) According to many half the men in the O/T would be hit with condemnation as they collect concubines and wives, whilst serving God.
My family is made up of couples living together, some for more than 25 years. I have seen marriages done the proper Christian way fall apart after five years. What was marriage in days of the OT and the NT, was it a massive religious ceremony or a legal contract? In the O/T, they may have sacrificed a lamb, had a party and exchanged money for the bride.. It wasn't a love relationship either ... and men had several wives. The brides were often about 14.....
Jesus said nothing about what makes marriage or about marriage and holiness, other then don't commit adultry and when divorce is acceptable. And he called those that judge others hypocrites, like the woman about to be stoned.
A marriage is consummated by having sex and the thing that makes it a marriage is a legal document. Fortunatly we are civilised enough to not push our 14 year old daughters into marriage, we don't have dowries which was biblical practice, and still practiced in the 19th Century in the West nor do we have to marry our rapists anymore. So why have we got so tied to what constitutes marriage in the eyes of God, that a couple that have lived together for 25 years, have been completely faithful to each other, will be together until they die are labelled "Fornicators and denying God.? And according to the fundies, I used to spent time with, it is my job as a Christian to call them sinners and tell them that God is not with them. And we wonder why people thing we are arrogant.
And why do people presume to know what other people's relationship with Jesus is? How does someone know that someone who is comfortable with their life and is comfortable with Jesus is wrong? There is a reason it is called a personal relationship with Jesus, it is personal, nobody else's business. I have no problem with sharing the Good News of Jesus but telling whether a person's heart is right before God and whether are "Truely born again" if they don't follow the party line.
People say that a Gay relationships is sinful, but most married couples start off living together, which many also condemn as sinful and just as harshly, yet nobody says they shouldn't marry or have civil recognition. My cousin is gay and want him to have the same civil rights that I do.
He doesn't need to told about what the bible says about being Gay, he is Catholic. I love him and accept him.
