Before you start saying who can marry who, remember this!
Marriage was around before Christianity, it’s not the church’s role to define it! Nor the courts for that matter.
For all those devout Christians who celebrate marriage, Christmas and Easter remember this, they were all Pagan rights before the church stole them and disguised them to attract Pagans and convert them.
If you celebrate any of these, you are a heathen before your own God!
