MOST CONTROVERSIAL TOPIC AND YOUR OPINION IS SERIOUSLY NEEDED
Now if a man is legally married to either 2 or 3 wives with each wife having about 4 to 5 children for him and such a man decides to be a member of a particular church which their doctrine doesn't permit two wive with all the wives and the children in the church .
What should the pastor of such a church do? 
Refuse them salvation or accept them into the church and ask him to divorce 2 and remain with only one?
