Define Christian. Somebody who goes to church every Sunday like he's told, or somebody who truly tries to live his/her life according to the teachings of Jesus Christ? Somebody who handles their business or somebody who gets in your face and tells you that you'll burn in **** if you don't repent?
Fellow Christian here. Catholic to be more specific. Perhaps you could start a discussion on Christian centric apps and app developers next time. Lets keep it relevant to the topic of Windows Phone ;-)
