They addressed it in church today.
First, only the wife is a member of the church. She serves in the choir. The pastor belongs to another church.
Second, there was a 2 hour interlude after the commotion began. All parties were listened to, grievances heard and councelling took place. 2 hours. After which (this much I'll trust the man of God) all parties wishing to distrupt the wedding apologized; one was in tears of remorse.
The couple was also counselled, after which they agreed to proceed with the wedding. The church lawyer is a pastor himself.
