Today I will be presenting on Augustine's Christology. Thus, I am making use of one of my favourite books: his Unfinished Work Against Julian. Julian was a Pelagian heretic who believed that essentially we save ourselves. Christ contributes a good example, but that's about it. So you see that when it comes to arguing about these things the question revolves around, how good are we, anyway?
When my wife and I discuss sexuality with our friends we are constantly walking that tightrope between immodesty and prudish, unhelpful vagueness. Should the rule be don't talk about sex in mixed company? A little strong, I think. It is, nevertheless, important to be extra careful in mixed company.
