The conference we had was about how to go about defending the Faith to others, basic apologetics for "dummies" so to speak. We don't have any set topics, so the defense of any Church teaching is up for grabs. Of course, in learning how to defend a particular teaching, one learns more about that teaching himself. So, bringing someone from the more traditional side in will also serve to help pull the attendees back to Tradition.
For example, I like the suggestion of John Medaille. The case here is that the VII Church has focused on social justice, but not from a traditional standpoint. So we either get hyper-capitalism (prosperity gospel) or hyper-liberalism (welfare state mentality). Other topics are the same way, as you all well know.
I don't have much time to write this morning, so maybe later I'll post a little more about our group's aims, and also my hopes for the direction the group takes. I really appreciate everyone's suggestions and have already sent a list to our group founder. (I'm on the board of directors)
