Uhhhh...More wedding problems?

I had a feeling the other day, a woman's intuition you could say, so I decided to give my church a call. When I asked them to confirm the wedding date that they had us scheduled for, they said the 26th of September, not the 19th that we have been scheduling all the vendors for..I was mortified. I called my photographer and my wedding reception venue to no avail, the reception site it booked for the 26th. I'm now trying to find a priest whose sermons we like so that we can check on his availability to marry us at our church because the father who was scheduled to marry us will be on a pilgrimage..::sigh:: talk about worst case scenario. But I'm blessed that I thought to call now instead of assuming everything was in place and then scheduling the rehearsal time for the day before the wedding only to get the response "But aren't you getting married next week?" David and I will press on and try and sort this all out.
