The corporeal dimensions of prayer before icons are often attributed to superstition, antiquated beliefs, or a “graced” function of metaphysical participation. In contrast to this, I develop a phenomenological analysis of corporeal substitution as a real possibility of ordinary experience, for an absent person we love strongly can come to presence in a thing before us and provoke a corporeal response. Guided by the story of the acheiropoieton, the “icon made without hands,” I show how the structure of this ordinary human practice is altered when elevated to prayerful substitution, and through its repetition over time, this allows the icon to serve as a means of communion for the believer across both visual and corporeal dimensions.
