There is no central missionary board to direct and manage the missionaries, and pay the salaries, coordinate mission fields, etc...
Not for the independent mission boards - they all have their own policies.
And the IFB missionaries do not get "Salaries" Their income is base on the
amounts different churches give to them
Now, the SBC does have the central missionary boards, as well as the American Bap Convention.
One other thing - even though we are SBC and do support the Co-op pgrm - we also support a IFB missionary.
