Passion-Bearers Boris and Gleb:  these two sons of St. Vadimir of Kiev allowed themselves to be slain by their wicked brother rather than spill innocent blood in a civil war.  They are unique ‘class’ of martyr that we can imitate on a smaller scale:  when we are faced with injustice done to us personally we can be silent and obtain grace from the Lord.
