St. Gregory Palamas on the Saints of the Church

from his homily "On All Saints":

Truly "God is glorious in his saints." Let us call to mind the martyrs' superhuman struggles, how in the weakness of their flesh they put to shame the evil one's strength, disregarding pain and wounds as they struggled bodily against fire, sword, all different kinds of deadly tortures, patiently resisting while their flesh was cut, their joints dislocated and their bodies crushed, and keeping the confession of faith in Christ in its integrity, unharmed and unshaken. As a result there were bestowed on them the incontrovertible wisdom of the Spirit and the power to work miracles. Let us consider how the patience of holy men and women, how they willingly endured long periods of fasting, vigil and various other physical hardships as though they were not in the body, battling to the end against evil passions and all sorts of sin, in the invincible inner warfare against principalities, powers and spiritual wickedness. They wore away their outer selves and made them useless, but their inner man was renewed and deified by Him from whom they also received gifts of healing and mighty works. When we think on these matters and understand that they surpass human nature, we are filled with wonder and glorify God who gave them such grace and power. For even if their intentions were good and noble, without God's strength they could not have gone beyond the bounds of their nature and driven away the bodiless enemy while clothed in their bodies.
