Lowest Common Denominator

What do AWANA, Max Lucado, Beth Moore and Lessons From Mayberry (and possibly others) have in common ? They all have managed to get their literature in congregations to be used as study material. While I am not sure all of these are used in ABA churches, some of them are. Where do you draw the line? Once you leave the truth to get literature from outside sources you get corrupt fruit from a corrupt tree (outside of the truth, all you can find is error). How do you get a Jezebel (someone not a church member and from false worship) teaching in a NT church? Make some popular literature and offer it as the hottest thing out there in religion. The church at Thyatira practiced pulpit affiliation (Rev. 2:20). Pulpit affilliation does not require a flesh and blood presence in the pulpit to occur! As best as I can tell, these offer nondenominational, renegade COC (ecumenical and instruments in worship), SBC (universal church and wrote off 1500 years of Baptist history) and moral examples types of literature used to replace the Bible and Bible based literature. If you can do it on a screen, be like the Protestants or do like everyone else is doing, you, too, will face the temptation to use the wrong material. When all congregations are using this lowest common denominator, the truth has fallen into the street, there will be a dumbing down and a loss of spiritual discernment. Has your church reached the lowest common denominator?
