Order of Justine Friars

The Order of Justine Friars (also known as the Justine Order or Order of St. Justus) is an Aurorian Hosian religious order with branches in both main Patriarchal Churches, though the original Order of Justine Friars belongs to the Aurorian Patriarchal Church, having rejoined the Selucian Patriarchal Church shortly after it resurfaced. As the oldest monastic order in Hosianism, it traces its roots back by communities established and operating under a rule formulated by St. Justus of Sipellum, who is considered to have established the Aurorian tradition of monasticism (as opposed to the earlier and more ascetic Augustan Hosian monasticism).

The Order is not a single order proper under a single authority but rather a confederation of monasteries looking out for its common interests and united by observing the Rule of St. Justus. Its widespread influence comes from the innovative practicality which St. Justus introduces to the formerly ascetic monastic tradition - the moderate monasticism of the rule of St. Justus made monasteries across the Hosian world adopt his rule. Justine monks take vows of stability, conversion of life and obedience.

The colour of their habits has resulted in the colloquial term Black Monks to refer to the Justines.
