There are many places in the United States that you can study to be a liturgist! First, you can look into doing a Certificate in Liturgical Studies. Most Graduate Theology Schools (Graduate Theological Union, Catholic Theological Union, and Notre Dame, for example) have programs that you can complete to get a Certificate in Liturgical Studies. If you are looking for a more serious program, I’d suggest starting an MA or PhD program in liturgical studies. Most major Catholic institutions have such a degree program, including the schools mentioned above as well as Catholic University and St. John’s College. If you are just fresh out of high school and interested in becoming a liturgist, I’d suggest starting with a BA in Theology or Religious Studies, which is a popular major at any Catholic Institution.
