Offhand, I can mention three:
Verdis Elementum: active in Caerwyn, Terran, and D'Hara.
Triunism: Active in Terran
Manifest Path: Active in Luria Nova (and Pian en Luries?)
There was a branch of Estianism in Madina, but I don't know if it is still around. I heard it was mostly defunct.
There was the Order of St. Iestyn in Pian en Luries, but I think it fell apart after the recent secession that formed Luria Nova.
