The fourth volume of the Complete Works of St. Ignatius contains a major theological work - “Ascetic Preaching” and a large array of newly published texts collected in the “Appendix” section. Here are presented in full the artistic works of the Saint - poems, sketches, memoirs, as well as literary and critical analyzes that significantly complement our understanding of this outstanding spiritual writer. Of undoubted interest will be the linguistic arguments of Bishop Ignatius, taught to teachers of religious institutions in the form of literature lessons. For the first time, the complete correspondence of the Saint with the abbot of the Cheremenets Monastery Anthony (Bochkov) is published from manuscripts, with an extensive essay on the nature of their historical views on many contemporary phenomena in social and church life. The volume closes with a complete bibliography of publications of the works of St. Ignatius himself and literature about him.
