I've changed my mind. Dr Miravalle's argument isn't so compelling on second thoughts. I still like the idea that truth is fertile. But that doesn't mean it has to bear fruit in new dogmas. Authentic and organic theological speculation would be perfectly adequate, especially in the context of liturgical poetry (Exhibit A: Akathist Hymn!). Oh, and how about lives transformed through the living Truth? That would be plenty fruitful, and considerably more so than dogmatic definitions. Faith is perfected in saints, not dogmas.
Dr. Carlton's argument is better. But it does still need to be nuanced. Once again, the liturgical poetry of our tradition celebrates the resurrection of reason from the death of heresy. The tragedy turns out to be of the paschal kind.
I realize my change of mind is not exactly newsworthy. But it might at least make someone's day. (Greetings to Abouna Justin!)
