If the guest parking at the church location is full, or if for any reason you would simply feel more comfortable parking offsite, there is a Repark coin parking lot down the hill from the church going toward Fussa. There are prepaid tickets available in the church auditorium, so feel free to pick up however many tickets you need for the day. (The typical cost for parking for the day is ¥600, so if you grab three ¥200 tickets, you should be good to go.)
