The AG published an opinion paper on disabilities nearly 8 years ago. Yet a small sampling of AG churches show there is not many with full fledged ministries. Of course, the AG also has a paper on healing, and yet many churches don't have a healing ministry.
In other forums, I've argued against some of the stances of other position papers. I would presume there are those that can articulate an argument against this one as well.
Many would presume that positions on healing and disability are mutually exclusive. After perceiving the lack of both of these ministries, I would probably argue they go hand on hand. After all, can't the same God who uses healings to bring people to faith through a demonstration of power, also use those with disabilities to bring people to faith through a demonstration of patience?
Read the paper, and then check out a local disability ministry near you.
