Do you have to have a minister do your wedding ceremony my bf and i are both agnostic and find it pointless and hard to find a minister due to our beliefs?

In a Word, no, you can have a civil ceremony - it is yourwedding after all, it's the one occassion when you can do what you want. A judge can officiate a wedding ceremony or, if you are on the coasts, a captain of a ship can officiate a wedding in international waters.

In other places, a registry office or a wedding celebrant.
