Let us approach it with burning desire and with our hands folded in the form of a cross let us receive the body of the Crucified, and applying our eyes and lips and forehead let us partake of the divine coal, so that the fire of the desire within us might receive the heat of the coal and burn up our sins and illuminate our hearts so that by partaking of the divine fire we might be set on fire and deified.
