In discussing theology, I like an interdenominational format.... and it's especially helpful if the participants are diverse, informed and articulate. When "likes" only talk to "likes" - little gets challenged, little is learned, and IMO there is little room for growth.
"Apologetics" (to defend one's position) IMO can be helpful - especially when the "position" is simply the message of Christianity, when it is Christ as Savior that is being defended. It is, in many ways, simply a form of Evangelism.
IMO, when speaking to others who are Christians embracing Christ as the Savior, "apologetics" often takes on a different form. Too often, it's just "sides" trying to defend a denominational stance or claim. I think what is often more helpful is to EXPLAIN that denomination's unique position or claim - too often that's not done; the "goal" rarely is to advance mutual understanding but to WIN THE WAR regardless of who is right and who is wrong, just as long as the denomination wins to fight. IMO, a forum like CH can present a great opportunity to hear from each other (even if we're mainly laity, even if perhaps our positions are best expressed as what I believe/think/feel/trust).
Personally, while I think apologetics is noble, I tend to avoid it. I DO engage in evangelism but I have a completely different approach to that (and RARELY engage in that here since virtually all here are already Christians). I don't care what denomination "wins the war" via tricks of argument and skills at debate. I'm pleased if - at the end of the day - I can say I learned something.... and maybe returned the favor. I'm not here to make ANYONE a Lutheran or cause ANYONE to think like me (other than that Evangelism point of Jesus is the Savior) - I lack the ego for that. And besides, in heaven, everyone will be Lutheran and will know that I was right all along. And that's soon enough for me.
