The purpose of this book is to provide more than a translation, but an interpretation from the original and rich writings of the Divine Liturgy of St. John Chrysostom. It can provide a better understanding of the liturgical aspects of the most used service in the Orthodox Church, particularly for Spanish speaking people who desire to come closer to the understanding of our services. May this can provide some help in their quest to come closer to the Divine Liturgy formed and written in the 4th century.
