Wedding decorations for a church?

Having an archway or decorated columns would be nice. You could use ferns and other greenery to decorate and even fall colored candles or tulle. Another way to tie in the theme would be to have your flower girl toss real or artificial fall colored leaves down the aisle instead of flower petals. If there is a Hobby Lobby store in your area you can gets lots of ideas by just walking through the store. The hay bales sounds like a cute idea. Fall colored fruits such as red and green apples or oranges in clear containers or vases would be nice centerpieces or decoration. The fall theme is very popular and you can find good ideas as well as beautiful pictures in bridal magazines.
