[@Lovejoy] Well... we have 'Inquisitor', 'Bishop', 'Cardinal', 'Vicar'... I imagine the lowest rank one can have is 'Acolyte', or 'Initiate', someone who is just newly joined... and since we don't actually know anything about this person, or the level of power they wield...

One idea was 'Varya's Sight', but that's more of an extended title. There was also 'Grand Cardinal', which is basically just saying 'I'm better than all these cardinals'. Other than that, no luck.
