The book by Agapios Landos "Salvation of Sinners" serves as an opportunity to delve into our historical self-awareness, in the anxious effort to preserve our ancestral reference to what preserved our identity, at a time when an entire race had neither a center of power, nor defensive strength, nor knew national borders, as it was a product of a universal empire and therefore obliged to survive in the historical vortex, with the strength drawn from the reservoirs of its own soul. In this climate, which every description is incapable of conveying, Agapios the monk Landos, of Cretan origin, appeared at the end of the 16th century. A man of broad education, he chose early on the monastic life of Mount Athos, where ascetic life, study, and writing sharpened his missionary zeal and sacrificial love for the suffering people of God... Simple and comprehensible language, a complete system of teaching the faith, an inductive method through examples, are elements that adorn the most beloved book of this harsh period, "Salvation of Sinners"... His speech always remains true and with spiritual precision spells out from the beginning the terms of faith and life. The author knows that he is managing the ultimate reserve of the endurance of the enslaved, their only survival, the essence of their soul. He sows the word of salvation in souls organized by pain and suffering and knows that true resurrection will quickly blossom.
