Fr Armand de Malleray, FSSP left France in 1994 after studying Literature for five years at The Sorbonne in Paris. After teaching French at the Military Academy in Budapest, he joined the Priestly Fraternity of St Peter in 1995 in Bavaria, where he was ordained in 2001. He authored the Art for Souls series of CD-ROMs presenting the Catholic faith through Christian paintings (each of the three volumes was granted official approval by the President of the Pontifical Council for Culture). His first priestly assignment was in London. He served in England since, apart from five years in Switzerland, then in an administrative position at his Fraternity's headquarters. Since 2008, he has been the editor of Dowry, the quarterly magazine of his Fraternity in the UK & Ireland. Several articles originally published in Dowry are included in this book.

The book is based on the author's preaching experience, especially to fellow clergy and seminarians. For a dozen years, Fr de Malleray has preached fundamental retreats to clergy on themes such as The Year of Faith, The Year of Mercy, Our Lady and the Priest, The Prayers of the Missal, The Priest and Martyrdom, The Priests and the Church, The Priest and the Four Last Things, etc. Fr de Malleray also gave talks on the Holy Eucharist at the International Eucharistic Congresses of Quebec City (2008) and Dublin (2012), and further talks in preparation for the National Eucharistic Congress in Liverpool (7-9 September 2018), as well as to Eucharistic ministers in the Portsmouth Diocese (on Eucharistic fragments and concomitance).

Fr de Malleray has been chaplain to the international Juventutem youth movement since its inception in 2004 (cf [...] and to their London group since 2015. The Juventutem logo is a monstrance and Eucharistic devotion holds pride of place in the movement. With the Juventutem young adults, Fr de Malleray took part in the World Youth Days of Cologne, Sydney, Madrid and Krakow. Juventutem worked hard to secure at World Youth Day official recognition for the Extraordinary Form of the Roman rite, centred on the Holy Sacrifice of the Mass. What was in 2005 in Cologne a sensational precedent has since become an expected and valued component of Word Youth Day.

By appointment from his superiors in the FSSP, since 2007 the author has been chaplain to the Confraternity of St Peter, a nearly 7,000-strong international prayer network in support of priestly ministry and priestly vocations.

Since 2015, Fr de Malleray is the rector of St Mary's Shrine in Warrington, Liverpool Archdiocese, where he also oversees the apostolate of his Fraternity in England and promotes vocations to the priesthood.
