Minister's Son, Pastor and Missionary guy walks away from Christianity.
It's a little more complicated than that. Watch the video. He started a group called Free Thought Exchange who's goal is to, well here's what his website says.
"OUR GOAL
Free Thought Exchange is about learning how to work and live agreeably along side those with different beliefs.
We are going into churches to speak as we attempt to bring believers and nonbelievers together for an open respectful dialog on issues of life, beliefs, and world-views. The goal is to change the way we perceive one another, its about tearing down common misconceptions people of opposing beliefs have about each other.
We are thoughtful and easy-going non-believers who are looking to open a dialog between Christians and non-Christians.".
