Who makes up the church — is it preachers and seminarians or ordinary people in the pew?

Les explains that verse 10 reveals why God made the mystery known: so that the principalities and powers in the heavenlies might be made known by the church, the manifold wisdom of God. Then he presses the question—who is the church? Not the seminarians, not the preachers only, but everybody. The common, ordinary person in the pew comprises the church, and those ordinary believers are the ones supposed to know the manifold wisdom of God. He illustrates with Tyndale, who wanted to get the Word of God into the hands of every plow boy in England, showing that no one is too uneducated to have the Word of God in his hands. Les says this is what God intends: He wants every single believer to study the Scriptures and understand them. He adds that nothing thrills him more than when someone says they disagree with him or get a little mad, but have determined to start studying their Bible.
