The Mystery to Be Entered

A Theological Guide to the Eucharist

for those preparing for Holy Orders

You are preparing to stand at the altar. There is no act more serious in the life of a Catholic priest — and none that demands a deeper understanding of what is actually happening.

This guide leads candidates for Holy Orders through the full landscape of Catholic Eucharistic theology: from the Old Testament roots in Melchizedek, the Passover, and the manna in the wilderness, through the patristic witness of Ignatius, Justin, and Augustine, to the definitions of Trent, the reforms of Vatican II, and the living devotional tradition of adoration. Written with particular care for those coming from an Anglican background, it treats the doctrine of the Real Presence, the sacrificial nature of the Mass, and the fruits of Holy Communion with clarity, precision, and warmth.

The Eucharist is not finally a subject to be mastered. It is a mystery to be entered. This book opens the door.

Prayer to St David

O God, who did call your servant David to be a preacher of the Gospel and a light to the people of Celtic communities, grant that we who honour his memory may follow his example: being joyful in faith, steadfast in hope, and faithful in the little things of daily life. Through the intercession of St David, may we drink deeply from the well of your grace, labour faithfully in your vineyard, and at the last come to that blessed rest where, with him and all your saints, we shall praise you for ever. Through Jesus Christ our Lord, who lives and reigns with you in the unity of the Holy Spirit, one God, world without end. Amen.
