Still, you can't take your husbands name, if you've got 'only' married in a church.
You're not 'legally' married, you're basicly missing all your family-rights.
For them (statists) it's the same like doing an online marriage by a pagan grain-worshipping cult somewhere in the far east.
They don't accept it, it's not a 'real' marriage, it's 'just a religious one'.
This is the sad truth.
