St. Macarius the Egyptian, Fifty spiritual homilies of St… (1921)
“ The immaterial divine fire has the effect of enlightening souls and trying them, like unalloyed gold in the furnace, but of consuming iniquity, like thorns or stubble; for our God is a consuming fire, taking vengeance on them that know Him not in flaming fire, and on them that obey not His gospel. It was this fire that worked in the apostles, when they spoke with fiery tongues. ”
