Episcopal Ministry and Charity
As bishop, Peter became known for extraordinary compassion toward those in need, especially orphans and widows. In years of crop failure he fed the hungry, and by tradition the food he set aside for famine relief never ran out. He also ransomed captives from bondage and tended to the sick and afflicted.
The synaxarion further credits him with the gift of insight. These works of mercy, rather than any single dramatic event, are the basis of his epithet "the Wonderworker."
