Virtually all IFB support missionaries thur independent mission boards - therefor they are cooperative just like the SBC.
The big difference is that instead of a missionary visiting over 500 churches in a span of 3 or 4 years to raise enough support to get to the mission field -as opposed to a SBC missionary - when approved - they are able to get right to the field.
Evan -ask you wife this - would your wife go to 15 separate grocers stores to the get the best price on different foodsuff, or does she look at the ads and consider the best store overall?
BTW, the SBC mission board is very selective - they will not appoint any divorced or tounge speaking missionaries.
There are five points of Fundamentalism:
Many IFB churches are NOT KJO
One other thing - anything above and beyond the fie points listed above - ie standards of dress, no alcoholic, no movies, no TV, refusing to fellowship with non-IBF, let alone non-Baptists, ect...
I would consider ultra-fundamentalists. In addition - I would add that IFB churches , as well as SBC, are like snowflakes - no two are alike.
Evan, your wife could go to another IFB, and find that is very different from her current church.
It appears that you have a serious situation here. And part of it is the C vs A. A good friend of mine once expalined that C-A is like a railroad track - right by you - there is a great distance - but as you look way down - the tracks seem to merge .
I'm thinking that this is one thing you may need to consider compromising.
I sincerely trust, that your home will soon be of one mind.
