Fr Jonathon Steele was born in 1995 in La Junta, CO and enjoyed a musical family life. His father was trained in musical theatre and traveled the United States in that role from a young age and his mother participated in various traveling choirs and eventually received a degree, majoring in musical education for voice. From the age of five, Fr Steele sang in choirs, competitions, and studied piano performance, considering the latter as a future profession. However, he entered the SSPX seminary in 2014 and, in 2017, received the role of schola master which he held for four years, learning to be a proficient director and teaching chant to the other seminarians.

Since being ordained in 2021, Fr Steele has been stationed at St Michael's School in south-central England. There he has taught Religion and Music for the past four years. For almost three years he has directed an extracurricular choir of eleven to sixteen-year-olds who have sung repertoire such as Durufle's Ubi Caritas, Josquin's Ave Verum, and parts of Byrd's Mass for Three and Four Voices. He also directs the mandatory school choir of eleven to thirteen-year-olds. His passion, however, is Gregorian Chant, a love which flowered at the seminary and which he wishes to share with his students as the years pass. Thus, just this year, he has begun a small school schola comprising five or seven of the young men of the school which he hopes, in time, will become the backbone of the Sunday schola in the chapels throughout the district of Great Britain and Ireland.

As a professional tenor soloist, he sang hundreds of performances on operatic, concert, and recital stages across the country.

Commander Sharpe (retired) is a 1993 distinguished graduate of the United States Naval Academy at Annapolis, Md., where he earned a Bachelor of Science degree with honors in English and emphases in political thought and history. He served for six years with the Navy submarine force and thereafter for two-plus decades as a public affairs officer. In 2000 he and a colleague founded IHS Press to reprint works of Catholic Social Doctrine by major Catholic thinkers of the early twentieth-century, and remains Chairman and Managing Director of the Press. He received his Master of Arts in History from Old Dominion University and completed all but the dissertation towards a Ph.D. in History as a Hagley Fellow at the University of Delaware.

CDR Sharpe's interest in music began very early. Through the 1980s, while in grade and high school, he sang and played guitar and piano more than weekly for the (Novus Ordo) Mass. A cradle Catholic born in 1971, he discovered “pre-Vatican II” Catholicism in 1993, while at the Naval Academy, at which point he left the Novus Ordo permanently for the traditional Mass. Already familiar with plainchant and classical genres, upon discovering the traditional liturgy he began singing with scholae wherever the Navy assigned him. He founded his first schola in 2006 at a small Latin-Mass chapel in southeastern Virginia. Soon thereafter, building upon his diploma in classical piano and AP work in music theory, he began an intense study of Gregorian organ accompaniment, and has since then directed and taught chanters either permanently or as a guest. In 2015, with his four older daughters, he began to study, perform, and direct small chapel choirs in polyphonic works from the Spanish, Flemish, Venetian, Roman, and other schools.

Professionally, CDR Sharpe served most recently for several years as Senior Legal Assistant with the Law Offices of Jeffrey E. McFadden, and is now Senior Paralegal Case Manager & Military Personnel Affairs Special Consultant at Reinhardt Vandenbrook PLLC. He raises sheep and chickens with his wife and those of their seven children who remain on the homestead, Bold Venture Farm. He is also beginning his second year in the evening J.D. program at the University of Baltimore School of Law.
