Things in themselves so supremely great, so far above man, so utterly above our perishable nature, as to be impossible for the race of rational mortals to grasp, as the will of God became possible in the immeasurable abundance of the Divine grace which streams forth from God upon men, through Jesus Christ the minister of His unsurpassable grace toward us, and through the cooperant Spirit. Thus, though it is a standing impossibility for human nature to acquire Wisdom, by which all things have been established—for all things, according to David, God made in wisdom—from being impossible it becomes possible through our Lord Jesus Christ, who was made for us wisdom from God and righteousness and sanctification and redemption.

Origen was considered one of the most important church fathers and his works were used widely in the Church. His work On Prayer was written around 230 AD. In it Origen talks about the object of prayer, the necessity of prayer, and the advantage of prayer. Heends the book with an exegesis of the Lord's Prayer.

Origen’s On First Principles is a foundational work in the development of Christian thought and doctrine: it is the first attempt in history at a systematic Christian theology. For over a decade it has been out of print with only expensive used copies available; now it is available at an affordable price and in a more accessible format. On First Principles is the most important surviving text written by third-century Church father, Origen. Origen wrote in a time when fundamental doctrines had not yet been fully articulated by the Church, and contributed to the very formation of Christianity. Readers see Origen grappling with the mysteries of salvation and brainstorming how they can be understood. This edition presents G. W. Butterworth’s trusted translation in a new, more readable format, retains the introduction by Henri de Lubac, and includes a new foreword by John C. Cavadini. As St. Gregory of Nazianzus, Doctor of the Church, wrote: “Origen is the stone on which all of us were sharpened.”

This beginner's guide to prayer will guide Catholics who need help learning to pray.
