If that's the case, most of us are in serious trouble.
While the premise has good intentions, it also seeks to block any efforts from those of us who have no pedigree. We're not allowed to teach, preach, or even have our opinions taken seriously. Fortunately, the Church of Christ doesn't hold to this, and will allow anyone to teach or preach who can assemble a decent lesson. The older members will render judgment on whether or not they know what they're talking about. On the downside, you get a lot of bad sermons and bible studies. But who said the congregation is where a person gets spiritual nourishment? Every man should be able to discern the word of God, not just the paid preacher.
A twenty-something graduate may be able to come out of a bible college knowing how to read Greek and quote verses from memory, but they lack the experience, hard times, and other tools that can only be sharpened on life's grinding wheel.
