Most of the attention to that corollary has been from Catholics, and most of that attention has been negative. I find that ironic in a way. The purpose of my effort has been to show that the filioque, as a doctrinal development, is compatible with what has always been affirmed in common by East and West; yet the main objection to my effort seems to be that the spirituque corollary, as a candidate for doctrinal development, is incompatible with what the West in particular has affirmed. Obviously I don't agree; it seems to me that the spirituque, which is not the main focus of my proposal anyhow, is being misunderstood to say more than it really says.
That's why it comes as a relief to me that Jonathan Prejean has now "got it." The amateur triadologists among my readers out there would do well to read his post. If you want to resume the discussion, we can all do it here, where its background is more easily accessible.
