While I believe if Jesus were alive he would be Pro-Gun, the church does not have the authority to do this. But otherwise I agree with your post.
Why not? of course they'd have to do it as a for-profit subsidiary of the non-profit organization (if they charged for use of it) but there is no biblical prohibition that I am aware of that stops a church from providing a service. A church food bank essentially serves as a grocery store. A church clothing bank serves as a clothing store. Several churches provide handyman services etc to their communities. Our Church serves as the local disaster preparedness center. Why could we not also operate a firing range? Training in the proper use of tools is a need that is often unmet in ou communities
