Every Christian wants to live according to the Gospel commandments. All church tradition is the experience of the fulfillment of Christ’s Truth, suffered through the suffering of the Holy Fathers. But how can we translate their centuries-old experience into our modern life? The book “Fundamentals of Spiritual Life” is a series of conversations by Archpriest Alexei Uminsky, built around the teachings of Abba Dorotheus, which occupy a special place in church tradition. This book is a lively and warm conversation about the most important things in the life of a Christian: about freedom and conscience, about the fear of God and prayer, about the memory of death and the fight against passions. The famous preacher talks about the invaluable experience of the Fathers of the Church and reflects on how we can apply it to our daily lives.
