This edition is dedicated to the five-year anniversary of the author's martyric death. How to avoid divisions in the Church while attuning the mind and heart to unity in Christ. Grace is to be sought from God, not from men. Can Christ really be divided? If Christ cannot be divided, how can His Body—the Church — be divided?

Talks on the First and Second Epistles of the Apostle Paul to the Corinthians. In 12 books. Book 1. — New Jersey, Daniel Sysoev Inc, 2016. — 224 pp.
