The Shorter Catecheses of Theodore the Stoudite (759-826) form one of the most celebrated collections of homilies in Byzantine monasticism. Theodore's writings deeply influenced Orthodox monasteries, serving as essential reading into modern times. This publication is the first translation into English of one of the abbot's most formative works. In addition to throwing much light onto a turbulent period of history, these Catecheses address many problems that the Christian faces today, including the crucial importance of community in the face of intense individualism and discipleship in an age dominated by self-serving convenience.
