Marriage pre-dates the Church and is for us all
It existed long before it, and other pagan rituals, were hijacked by the Church. It’s about love between two people. Homosexuality existed before
Christians formed their Church; it was widely accepted. Don’t concern yourself about how other people live, once they are harming no-one and are happy. To me, it’s traditional, heterosexual family units that seem to be in turmoil.
