As the body of the Lord was glorified when he climbed the mount and was transfigured into the divine glory and into divine light, so also the bodies of the saints are glorified and shine like lightning. Just as the interior glory of Christ so covered his body and shone completely, in the same way also in the saints, the interior power of Christ in them in that day will be poured out exteriorly upon their bodies.
For even now at this time they are in their minds participators of his substance and nature. For it is written: “He that sanctifies and the one who is sanctified are of one” (Hebrews 2:11). And: “The glory that you have given me, I have given them” (John 17:22). Similarly, as many lamps are lighted from the one, same fire, so also it is necessary that the bodies of the saints which are members of Christ become the same which Christ himself is.
Macarius the Great, from The Fifty-Three Spiritual Homilies
Macarius the Great (295-392) was among the most authoritative of the Desert Fathers and a disciple of Anthony the Great. His spiritual writings are among the most highly valued in the Eastern church. They have come to be highly regarded also in the Western church. The 18th century British revivalist, John Wesley, wrote in his diary: “I read Macarius and sang.” Wesley would go on to translate Macarius’s Homilies for his traveling preachers. The Fifty-Three Spiritual Homilies have one purpose — to help bring individuals to God in absolute devotion.
