The icon we keep
The Ladder of Divine Ascent.
Theosis — to be made, by grace, like God — is the whole end of the Christian life. The app draws its name, and its icon, from the ladder of St. John Climacus: the long ascent kept one rung at a time, in prayer, in Scripture, in the daily round of the Church.
The image is a twelfth-century icon from Sinai — monks climbing toward the waiting Christ, the angels looking on, the struggle laid plain. It is the work Theosis is made to serve.
