A Christian Holiday
an essay in the public domain
The soul declares that it was disguised because in the ascent through faith its garments, apparel, and capacities were changed from natural to divine. On account of this disguise, neither temporal nor rational things nor the Devil recognized or detained it. None of these can do harm to the one who walks in faith.
The soul’s advance, moreover, was so concealed, hidden, and withdrawn from all the wiles of the Devil that it indeed involved darkness and concealment. That is, the soul was hidden from the Devil, to whom the light of faith is worse than darkness. We can say as a result that a person who walks in faith walks concealed and hidden from the Devil.
John of the Cross, Ascent of Mount Carmel, Bk 2
