Jesus said that the gospel was to be preached to the whole creation (Mark 16:15-16). Paul said the church is the "pillar and ground of truth" (1 Timothy 3:15). As such, it is expected to stand under and support the truth in the world.
This divine task can and will be accomplished in harmony with the wisdom of the Being who ordered it when each congregation "sounds out the word of the Lord" under it's own elders, using it's own resources, and answering to no board or conclave knwn to man. It will be accomplished when each disciple, whose heart burns with a love for souls, personally does all he can to teach the truth, wherever his influence extends.
