Priest is a position within the Lancea Sanctum. While Bishops handle Sanctified affairs at the street level, Priests tend to individual Kindred, providing spirtual guidance and counseling. They give sermons and officiate over Apostolica and Ecclesia. Priests are typically sociable individuals (as they are the ground-level Kindred that most other Kindred would deal with on a regular basis), but they must also be well-versed in the Testament of Longinus and must have some measure of detective skill, to report any bits of heresy they discover to the Inquisitors. There are typically two Priests per Bishop in a city, but the numbers can vary. In addition to oaths of loyalty to the covenant, Priests often take vows (perhaps to feed on only certain vessels, perhaps to perform Ecclesia for any coterie that asks, etc.) and wear easily-identifiable clothing, so that others may find them should they require confession. Priests typically have low Status in their covenant, as their public nature leaves them little time for political manuvering.
Alternate titles for Priest include: Pastor, Father/Mother, Pendicant
