Without taking a stance on the Council of Chalcedon, which I think is more complex and has greater context in the goings on of it's time than is commonly understood, I like this column. Though I am not a big fan of some aspects of Eastern and Coptic Orthodoxy, I have read some of the desert fathers and find their mysticism a real strength of their tradition that is not necessarily as fully replicated in the west as might hope for. Theosis and divinization are I think important concepts that are somewhat analogous to sanctification, but which personally carry more meaning for me than sanctification, and to some degree a distinctive meaning.
As we gradually define what Liberal Catholicism is in the context of this forum, I would hope that one of the things that will be folded into this tradition is an openness to the traditions of the Eastern churches and of other faith traditions within and without of Christianity that help us on our spiritual walk rather than a defacto rejection of them simply because Roman Catholics didn't come up with them, or because some element of them contradicts an obscure point of theology.
Maybe we could do the contemplative journey here that OBOB rejected, if I am understanding correctly that you wanted to lead some sort of spiritual study or mediation over the course of several days like a bible study (Maybe I am misunderstanding and you were just speaking of it in general terms as to whether or not it is an acceptable practice or not.). What would be involved? Do you have a link to that thread? Or maybe could you could start fresh here and talk about what we'd expected to do each day to participate if you're prefer?
