Atlanta (CNN) -- The arrest of Georgia megachurch pastor Creflo Dollar brought renewed attention to his message of the Prosperity Gospel, controversial to some and faith-fulfilling to its followers.
Dollar, who was arrested last week after allegedly assaulting his teenage daughter, is the founder and pastor of World Changers Church International in suburban Atlanta.
It claims about 30,000 members and has a multimillion-dollar sanctuary that resembles a golden-domed spaceship atop a hill.
Dollar said in a statement he would never harm his children and that the facts in the case would be handled privately.
Prosperity ministers preach that God rewards the faithful with wealth and spiritual gifts. Pastors such as T.D. Jakes, Dollar, and Joel Osteen have become the Prosperity Gospel's most well known preachers, building megachurches and business empires with a message equating piety with prosperity.
While popular in the black church, it is not a solely black phenomenon, as seen in the ministry of Osteen, a best-selling author and megapastor at Lakewood Church in Houston. The church website says it is considered to be the largest church in America, with more than 38,000 attendees.
The Prosperity Gospel is a form of evangelical Christianity that largely grew out of the booming economy of postwar America, says Jonathan Walton, a professor of Christian Morals at Harvard and author of "Watch This! Televangelism and African American Religious Culture."
The theology's emphasis is on God's promised generosity in this life and the ability of believers to claim it for themselves. If God loves us, it teaches, then God will reward us with a new home, a good job, or good health, Walton says. God wants us to be prosperous.
One of the problems that conservatives tend to have with prosperity theology is its focus on material prosperity, says Ben Phillips, a theology professor at the Southwestern Baptist Theological Seminary in Houston.
"The Prosperity Gospel tends to mask the greatest need that any individual has, and that's to be reconciled to God through faith in Christ," Phillips says.
"The point is that God is the ultimate good," he continues. "Knowing Him, being in a relationship with Him ... in which He is God and we are His creatures, that is where joy is found."
Believers may argue, however, that material wealth is evidence of being in covenant with God, says Michael Long, a teacher of religious studies at Elizabethtown College and editor of the book, "I Must Resist: Bayard Rustin's Life in Letters."
Those believers might say material goods are a side effect of believing in God and Christ, he says. "The focus is on getting right with God, but you know that when you get right with God, you're going to get something for it."
While the theology may attract more followers in a time of economic boom, the fact that it focuses so much on the individual and controlling one's own heart is a comfort in tough economic times as well, Long says.
Tom Brown, senior pastor of the Word of Life Church in El Paso, Texas, says wealth and prosperity are what God desires for us.
"Just as any parent enjoys watching their kids have fun, God delights in watching His children enjoy what money can buy," Brown writes on the website for his ministry. "I believe God is love and He desires the best life we can have."
Believers must then use their wealth to help others, Brown says -- and that to have money for its own sake is pointless.
Phillips says it's true that the Bible teaches Christians to care for the poor, sick and needy, "but the Bible also teaches that God uses and permits suffering in the lives of people for His own ends and purposes."
He points to the Book of James, which says we must value the trials in our life because they shape our character.
"Believers in humble circumstances ought to take pride in their high position. But the rich should take pride in their humiliation -- since they will pass away like a wild flower," it says in James 1:9-10.
Critics may say prosperity followers are wrong, but believers say they are sincere, Walton says. The pastors may be pop culture celebrities, but it doesn't mean their congregations don't find fulfillment in the message.
The pastors' wealth, derided by some as evidence of hypocrisy, could also simply be seen as evidence of their faith, Walton says.
"The wealth is part of their authority," he says.
