Defense of Orthodoxy in Maramureș
Joseph's episcopate fell during a period of severe trial for the Orthodox of Maramureș, when Roman Catholic authorities in the region sought to eliminate the Orthodox confession. The Orthodox account describes him as a zealous defender of the faith who upheld his people against this pressure.
For his commitment he was persecuted by the local authorities and imprisoned. His endurance of these sufferings while continuing to shepherd his flock is the basis on which he is honored as a confessor — one who suffered for the faith without dying a martyr's death.
