His Grace Abba Raphael's Master's thesis, which is on the Economy of Salvation According to the Catholic Church from a Biblical, Patristic, liturgical and canonical standpoint, came at a time in which erroneous teachings were circulating; teachings which are foreign to our mother Church; teachings which are at odds with Holy Scriptures, the saintly Early Fathers, and all who have taught us throughout history. His Grace began responding to some of these erroneous teachings, which are strange to our Coptic Orthodox Church, and expounded at length the topic of "Economy of Salvation."
