I am getting married in September. We are not getting married at a church but the FI's father asked the pastor of his church to do our ceremony. The church isn't charging us anything for his time, but I know I have to give some sort of donation to the chuch. I do not attend church. Anybody have any advice regarding a donation to the pastor/church and at what point to do so? Would he get one of the envelopes like all the other vendors??
