Disclaimer : We are NOT a Church we are medieval reenactors.
The middle ages was called the age of Faith. This is reflected in our society, where for good or ill, religion and politics were often one and the same. We are Priory with a "monastic" Prior, who is of the Templar Order and thus also the military commander of Tortosa.
Tortosa also in time will have a Bishop, and perhaps a Cannoness. Priest and Chaplain brothers, nuns, monks and whatnot are all available as potential personas but must be portrayed with respect and without bigotry.
