Can I just add...
In my area it is pretty common for members of the congregation to go to wedding ceremonies without an official invitation. Because it is God's house it's taken that everyone is welcome at all times. So no one would need an actually invite unless they were going to the reception...
It's almost as if there is a standing invite to the whole community.
Having said that, it tends to be distant family friends & old ladies of the parish who go to all the weddings!
But I went to a wedding yesterday, although my formal invite was just for the reception.

(It's
totally normal over here to invite certain people at night & certain people for the whole wedding)
I wanted to grab a couple of photos of the B&G so I could print them out & give them to them at the reception... They loved the surprise of having wedding photos already!
So my take on it would be: The members of your church should know that there is a standing invite, because it is God's house & you can't possibly say who is allowed inside. So there is no need to actually invite the people that you don't want to attend the reception.
How is it normally handled in your church post-wedding? Is there normally any sort of reception, or do people who aren't invited just go on their way? (we never have anything laid on for the people who just wanted to witness the ceremony without being invited)
