What does this mean?

QUOTE: "We have to recognize that we've created the system that we loathe. I don't think the reason 15 percent serve is because 85 percent are lazy. We've created a system that glorifies the clergy and marginalized the laity. We got the outcome we created programs for. We've become ‘clergified.' There's a three-tiered structure: laypeople, clergy and missionaries. ... All religions tend to create a class of people who are above others so 1) they can revel in that and 2) the rest of us can say it's their job. Christianity was started without any of those structures, and ended up like so many false religions do when they create a ministry caste structure. When we see real movements of God take off, they happen when people are free." -Lifeway Research director Ed Stetzer [rev.org, 2/09]
