Ascetic Discipline
The discipline for which Zachariah is principally remembered was a near-total renunciation of prepared food. The synaxarion relates that he refused anything baked or boiled, restricting himself to raw greens, and that he broke this single daily meal only at sunset. Such a rule of eating is presented in the tradition as the outward sign of an inner austerity that set him apart even among the ascetics of the Caves.
