This chapter serves as the textual analysis of the treatise. The theological distinctiveness of this work focuses on worshiping the Holy Trinity, while critiquing the widespread practice of calling upon angels, martyrs, and saints. Of course intercession is widely observed throughout Christian Ethiopia, Eastern and Oriental Orthodoxy, other Christianity denominations, and most other Abrahamic Faiths. Yet, the manuscript’s focus on worshiping the Trinity and the cultural practices advocated within the homily are born of the teachings from the fifteenth-century monastic movement founded by Abba Estifanos, as verified by today’s Estifanites. Though The Book of the Trinity is well attested to in archives around the world, it has largely remained untouched, and this homily is the first treatise representing the theology of the Daqiqa Estifanos (Disciples of Abba Estifanos). This homily, originally written by the 18 founders of the Order almost 600 years ago, endured tumultuous historical epochs, yet remains a symbol of the Estifanite’s perseverance through two generations of banishment, until their reconciliation with the Crown and the church, and their eventual return to the Ethiopian Orthodox Communion.
