I have no problem with someone studying other views when it fits with the course objectives. Each of the people you state fit well in a survey class, which can be taught at a freshman/sophomore level in college. Why do you imagine that Christianity is relegated only to seminaries. That's just foolish as nearly every Christian University has general electives pertaining to the faith.
I have never said that Christianity is relegated only to seminaries. You've switched the wording to make it appear as such. I said that Liberty University is not a parachurch organization, but I could understand how the seminary would be. That is very different from what you are trying to make my words mean.
Do you believe that a doctors office full of Christian doctors, maintaining Christian ethics, constitutes a parachurch organization? Yes, of course you do because that's how you define parachurch. But you are wrong. Could it be? Yes, if the practice became an evangelistic mission.
Here's another example. I manage a company that stresses Christian values in how we conduct business. We attend and allow our employees to attend functions and dinners at church, and we provide the cost for the events. By your standard we are a parachurch organization. But we are not. Our focus is business and to make money (ethically).
Did you graduate from Liberty University, or are you a current student at the university?
