Because it is so topical to the debates going on at the moment in the Catholic Church, we have been considering the Truth that the Universal Catholic Church is ontologically prior (see earlier posts for that weirdo expression) to the local Church; and understanding how wrong the Kasperites are in putting the local Church first and concluding that it's OK for Northern European local Churches to abandon the received Tradition of the Universal Church on matters like Communion for Remarried Divorcees; and those in genital homosexual relationships.
C S 'Anglican Patrimony' Lewis's Devil Screwtape wrote like this about the Church:
"One of our [Devils'] great allies at the present is the Church itself. Do not misunderstand me. I do not mean the Church as we see her spread out through all time and space and rooted in eternity, terrible as an army with banners. That, I confess, is a spectacle which makes our boldest tempters uneasy. But fortunately it is quite invisible to these humans."
Lewis here brilliantly reminds us of the synchronic as well as diachronic aspects of the Church; i.e. that it is not only spread throughout the world at this present time but throughout all of time. It is more than just what you see around you.
