Rev. Vincent Woo, J.C.D.

Rev. Vincent Woo, J.C.D., teaches canon law and serves as the Director of Liturgy at St. Patrick’s Seminary. He is also a faculty member of the Catholic Institute of Sacred Music and the Permanent Deacon Formation Program of the Archdiocese of San Francisco.

A native of Hong Kong and a student of Joseph Cardinal Zen, he was ordained to the priesthood in 2017. His initial pastoral assignments included ministry in a parish, a hospital, and a homeless shelter in his hometown. While pursuing his doctoral degree, he served as a regular confessor at the Basilica of the National Shrine of the Immaculate Conception in Washington, D.C., and as a chaplain to a women’s religious community. He has also served at St. Catherine of Siena Church in Burlingame, CA.

At the chancery of the Archdiocese of San Francisco, he served as priest-secretary and Master of Ceremonies to Archbishop Salvatore Cordileone. He oversaw the Office of Worship of the Archdiocese, organizing major liturgies such as the Chrism Mass, Ordinations, the Walk for Life Mass, and the Rite of Election.

As a canon lawyer, he currently serves as a Defender of the Bond for the Diocese of Oakland, having previously served as a stable advocate for the Archdiocese for the Military Services, USA. He has also been involved in both penal and marriage nullity cases for various dioceses on an ad hoc basis. Additionally, he currently serves as an appointed member of the Sacramental Law Committee of the Canon Law Society of America.

Fr. Woo regularly publishes articles in both academic and non-academic publications. In 2024 and 2026, he was invited by Raymond Cardinal Burke to speak at the Speculum Iustitiae Conference for Canon and Civil Lawyers in La Crosse, WI.

He believes that canon law is intrinsically oriented toward the salvation of souls and the regulation of justice in the Church. Drawing on his experiences, he hopes to instill in seminarians the conviction that an appreciation of tradition, a robust interior life, and faithful observance of the law are fundamental to the worthy celebration of the Holy Sacrifice of the Mass.

Beyond canon law and liturgy, Father Woo has a keen interest in the liberty of the Church in China and Hong Kong. He has appeared on EWTN’s The World Over with Raymond Arroyo and has been quoted in the U.S. Department of State’s International Religious Freedom Report. His hero is Ignatius Cardinal Kung, who was imprisoned by the Chinese Communist Party for nearly 33 years for refusing to join the patriotic association in the 1950s.
