Sorry about St. Johns, but at least one of the churches, St. Pauls with Rev. Leighton, has looked deeper into the matter and apparently the Bishop not only has no legal right to take their property, but if he pushes the issue he will be arrested for tresspas if he sets foot on the grounds.
Very interesting! I wonder if this has been conveyed to the other four of the CT 6 churches (though I'd be surprised if it hasn't).
