Christ prayed for those that crucified Him: ‘Father, count not this sin against them; they know not what they do.’ Archdeacon Stephen prayed for those who stoned him so that the Lord would not judge this sin against them. And so we, if we wish to retain grace, must pray for our enemies. If you do not find pity on a sinner who will suffer in flames, then you do not carry the grace of the Holy Spirit, but rather an evil spirit; and while you yet live, you must free yourself from his clutches through repentance.

St. Silouan the Athonite

By the death of martyrs religion has been defended, faith increased, the Church strengthened; the dead have conquered, the persecutors have been overcome.... So, too, David rejoiced in prophecy at the departure of his own soul, saying: ‘Precious in the sight of the Lord is the death of His saints.’ He esteemed death better than life. The death itself of the martyrs is the prize of their life. And again, by the death of those at variance hatred is put an end to.

St. Ambrose of Milan
