Despite the ecclesiastical name I don’t know of any particular connections with the church for this fly. It is a dabbler style pattern for use when fishing for sea trout and salmon but I can see no reason why it would not work for brownies too, especially around the time of the mayfly hatch.
It is an easy fly to tie with the body in two parts, yellow seals fur at the front and red seals fur at the rear. A silver rib and a GP crest for a tail with a bronze mallard cloak and some JC cheeks complete the fly.
I like to think that the combination of yellow and red hackles is the key to this patterns success, but until we find a method of communication with the fish I will never really know. I tie this one up in sizes 8 down to 12 but you could rattle some up on bigger or smaller hooks if you so desire.
Keep the Jungle Cock cheeks small, if they are too big I think they detract from the yellow/red trigger.
