really so does the church decide on who gets the house and kids, does the Church marry a muslim to a Christian, does those who do not believe get married in a church.
Thinking it’s only the Church and God is great when one thinks of everyone as a Christian but all are not.
I always say that it is the property of religious institutions. Churches, Mosques, synagogues, etc. If you don’t believe in a God, I wouldn’t call that marriage. It’s more an easily dissolvable union of financial interest.
