Vassa Larin

Dr. Sr. Vassa (Barbara) Larin (born Varvara Georgievna Larina, Russian: Варвара Георгиевна Ларина; December 11, 1970) is an American nun with the Orthodox Church of Ukraine. She is the author of many scholarly articles and a monograph on Byzantine liturgy and theology, and an outspoken public intellectual on current issues of the Russian Orthodox Church Outside Russia (ROCOR), of which she was formerly a member. She teaches Liturgical Studies at the Catholic Theological Faculty of the University of Vienna in Austria, and is Professor of Practical Theology of the Kyiv Orthodox Theological Academy.

Sister Vassa was a member of the Commission of the Inter-Council Presence of the Russian Orthodox Church: the Commission on Liturgy and Church Art, and the Commission of the Inter-Council Presence of the Russian Orthodox Church: the Commission on Canon Law.

Varvara Georgievna Larina was born to the family of a Russian Orthodox priest in Nyack, New York. Larin graduated from Nyack High School and entered Bryn Mawr College in Bryn Mawr, Pennsylvania, at the age of 16. She left college to enter the Lesna Convent of the ROCOR in Provement, France, at age 19. After ten years in France, she spent two years at the Mount of Olives Convent in Jerusalem. Following a long spiritual and academic novitiate training, involving the study of Greek, Latin, German, Patristic Theology and Church History, Vassa was eventually enrolled by Archbishop Mark (Arndt) of Berlin and Germany to study Orthodox Theology at the Orthodox Institute of the Ludwig Maximilian University of Munich, Germany. There she received a master's degree in Orthodox Theology, having written a Master’s Thesis on the “Royal Office” at the beginning of Byzantine Orthros.

In 2006-2008 she worked as the Graduate Assistant of expert on Byzantine Liturgy, Professor Robert F. Taft, S.J., at the Pontifical Oriental Institute in Rome. Taft directed Sr. Vassa’s doctoral dissertation on the Byzantine hierarchal liturgy, which she defended summa cum laude at the Orthodox Institute of the Ludwig Maximilian University of Munich in December 2008. A revised version of Larin’s dissertation, titled The Byzantine Hierarchal Divine Liturgy in Arsenij Suxanov’s Proskinitarij, was published in 2010 as volume 286 of the academic series Orientalia Christiana Analecta.^[1]

Beginning in January 2009, Larin taught Liturgical Studies at the Catholic Faculty of the University of Vienna in Austria.

She is a founding member of the Society of Oriental Liturgies, and a member of the North American Academy of Liturgy.

Larin has grown an online presence with Coffee with Sister Vassa, a podcast and video series discussing catechism which she established in 2013.^[2][3][4]

Latin has been a staunch critic of the Russia Orthodox Church's support of the Russian invasion of Ukraine.^[5] In March 2022, she called the invasion "evil", and in May signed the Volos Declaration, which declared the concept of "Russian world" as taught by the church as heresy.^[3]

On 12 May 2025 the Synod of Bishops of ROCOR issued a decree reducing Latin to layperson status, and forbidding "the former nun Vassa from wearing monastic attire...and from presenting herself in public appearances as a nun of the Russian Church Abroad."^[6] Larin has since aligned herself with the Orthodox Church of Ukraine.^[5]

Her numerous publications, written in English, Russian, or German, include scholarly studies based on original manuscript-research, as well as articles on controversial topics in contemporary Orthodoxy.^[7]
