Peter Andrew Kwasniewski (born 22 March 1971) is an American traditionalist Catholic writer and composer of sacred music. He is a senior fellow of the St. Paul Center in Steubenville, Ohio, and was formerly on the faculty of Wyoming Catholic College. He is also the author of three books about traditional Catholicism: Resurgent in the Midst of Crisis, Noble Beauty, Transcendent Holiness, and Tradition and Sanity.

Life and career

Kwasniewski was born on 22 March 1971 in Arlington Heights, Illinois. He grew up in New Jersey. At the Delbarton School in Morristown, he received his first serious tutelage in music. After a year at Georgetown University, Kwasniewski matriculated as a freshman at Thomas Aquinas College in California, where he earned a B.A. in liberal arts in 1994. He subsequently studied at The Catholic University of America, focusing on ancient Greek philosophy and medieval scholasticism. He received his M.A. in philosophy in 1996, writing a thesis on "The Dialectic of Reason and Faith in Descartes's Meditationes de prima philosophia" and his Ph.D. in the same discipline in 2002, with a dissertation on "The Ecstasy of Love in Thomas Aquinas".[1]

He served as Assistant Professor of Philosophy from 1998 to 2006 at the International Theological Institute for Studies on Marriage and Family in Austria (then in the town of Gaming) and as an adjunct instructor in music appreciation at the Franciscan University of Steubenville's Austria Program located on the same campus. In 2006, he joined the founding team of Wyoming Catholic College in Lander, Wyoming, where he served as assistant academic dean and director of admissions, and then as choirmaster and Professor of Theology and Philosophy. He also taught music and art history in the college's fine arts curriculum.

At the end of the academic year of 2017-18, Kwasniewski left Wyoming Catholic College. He accepted the position of senior fellow at the St. Paul Center in Steubenville, Ohio, and is currently working as an independent writer, editor, publisher, and guest lecturer, giving talks and workshops on the traditional liturgy of the Catholic Church.

Kwasniewski is a board member and scholar of the Aquinas Institute in Green Bay, Wisconsin, which is publishing the Opera Omnia of St. Thomas Aquinas. He is also a fellow of the Albertus Magnus Center for Scholastic Studies.

Public reception

Kwasniewski's books, lectures, and articles have meet with both considerable praise and opposition. Major prelates and Catholic magazines and websites have praised Kwasniewski for his insights into the crisis in the Church, while others have criticized him for insubordination to the present wishes of Church leaders. Some, like Fr. Anthony Ruff, OSB, of the PrayTell blog, have criticized Kwasniewski for an intransigent defense of traditional things, especially preconciliar, and for his apparent rejection of the reforms intended by the Second Vatican Council. Ruff, in particular, argues that Kwasniewski depends excessively on the Council of Trent, whose doctrine was completed and corrected by Vatican II.[2] Jonathan Daly maintains that Kwasniewski's vocal preference for traditional worship is itself characteristically modern because it is a lifestyle and worldview choice over against other options that have more to recommend them, such as the contemporary magisterium.[3] Support for Kwasniewski's positions and writings has also been substantial. In 2016, the international Catholic TV station EWTN broadcast a TV interview with Kwasniewski on their popular "EWTN Live" channel[4] and also began carrying his book Resurgent in the Midst of Crisis in their online catalog.[5] That same year, TV Infobar made available the video of the book launch of the Czech translation of Resurgent, at which Cardinal Burke introduced the book, calling it "very readable and very accessible" and thanking Kwasniewski "for giving us this work."[6] Other positive publicity for this book included The New Oxford Review, which claims that "Kwasniewski accurately sums up the current situation in the Church" and that Resurgent is "a starting point for serious discussion" for "revitalizing the Church".[7]

His book Noble Beauty, Transcendent Holiness was praised by The Catholic Herald in Britain and the National Review, both of which published favorable reviews.[8][9]Fr. Zuhlsdorf also reviewed the book favorably, claiming that "He writes with clarity and great force, which surely reflect both his deft mind and his convictions."[10]

In 2016, it was revealed that Kwasniewski was among the clergy and theologians who signed the "Letter of the 45", a letter to all the Catholic cardinals which asked them to "respond to the dangers to Catholic faith and morals" which they alleged that Pope Francis' Amoris Laetitia had posed.[11] Kwasniewski was also a signatory of a letter in support of the four Dubia cardinals.[12]

In April 2019, Kwasniewski was among 19 Catholic scholars and clergy who signed a 20-page open letter making a formal accusation of heresy against Pope Francis.[13]


In addition to being a teacher and writer, Kwasniewski has enjoyed a parallel career as a choirmaster, cantor, and composer of about 150 works of music.

After studying composition and conducting with Roy Horton and voice with Carol Horton at Delbarton School in Morristown, New Jersey, Kwasniewski became assistant choir director at Thomas Aquinas College in Santa Paula, California (1990-1994). He served as director of the Schola Cantorum at Old St. John's Catholic Church in Silver Spring, Maryland (1994-1998), director of music at the International Theological Institute in Gaming, Austria (1999-2006), and founding choirmaster and schola director at Wyoming Catholic College (2007-2018).

Kwasniewski's Mass settings, motets, hymns, carols, antiphons, and acclamations have received numerous performances from 1990 to the present. His Mass settings include Missa Spiritus Domini (1994), Missa Spe Salvi (1995, rev. 2012), Missa Brevis à 3 (1997), Missa Hereditas Mihi à 3 (2016), and Missa Honorificentia Populi Nostri (2017). His Seven Mandatum Antiphons (2010) were dedicated to Arvo Pärt on the occasion of his 75th birthday; the maestro personally accepted the dedication. Many of these works can be found in his book Sacred Choral Works, which was highly acclaimed when it first appeared in 2014. Ensembles that have performed Kwasniewski's choral music include the Ecclesia Choir (dir. Timothy Woods), the Vittoria Ensemble (dir. Rick Wheeler), the Scottish ensemble Cantiones Sacrae (dir. Graeme Adamson), and Cantus Magnus (dir. Matthew Schellhorn).

Kwasniewski has also written a three-movement wind quintet Fire and Flame, premiered by the Antero Winds in 2012; an Ave Maria for SATB, winds, and strings; a violin sonata; organ accompaniments for English plainchant; and pieces for brass quartet and string quartet.

He has published numerous articles on music, especially on the recovery and renewal of sacred music in the contemporary church.
