You think that just because they're married, they can do whatever, wherever? That's like saying, because Michael Jordan is a professional, he can dribble down the center aisle and dunk in the baptismal pool. I don't think the Bible says "the marriage church altar is undefiled", lol. The altar is not your bed. It's not even your house 
What lesser things do we not permit in the sanctuary? But then something like this... 
The couch is NOT a bed.
The floor is NOT a bed.
The kitchen table (though sturdy) is NOT a bed.
The top of my car is NOT a bed.
The towel in the grass in the back yard is NOT a bed.
The shower is NOT a bed.
The top of my baby grand is NOT a bed.
The inside of the kitchen sink is NOT a bed.
THESE THINGS ONLY SERVE AS A BED WHEN TREATED AS SUCH...
A pew (though cushiony and soft) is NOT a bed....
[/rant]
Couples can speak in tongue when they "make it", but they can't do it at church?
Now ON THE ALTAR is a bit much. But it's like gambling .... I haven't read a page that said DO NOT, and until I do .... Paula Deen's ... have my chicken ready.
