Pastor Aaron Yi

Born into a Korean Methodist Christian family, Aaron majored in theology at Yonsei University in Seoul, Korea. After receiving God’s call to become a minister who combines theology and music, he went to Europe and obtained a German National Certificate of Protestant Church Musician in Munich, Germany, and a Master’s Degree in Organ Performance in Paris, France. After finishing his music education, he came to Boston and attended Boston University School of Theology, earning a Master of Divinity and a Master of Sacred theology in liturgical studies.

During his past 13 years of pastoral ministry in St. Albans and St. Johnsbury, Vermont, Aaron has enjoyed spending time outdoors hiking and kayaking. He has also performed organ concerts in a couple of churches and lead choirs and handbell ensembles during worship time.

He and his wife have three sons: two have graduated college and are now working full time in Boston and LA. The youngest is a freshman in high school.

Aaron is a lover of music, arts and history. Influenced by several great writers such as Eugene Peterson, Richard Rohr, Rabbi Jonathan Sacks and liturgiologist Alexander Schmemann, he constantly seeks to design creative worship with fresh perspectives on biblical interpretation for transformative Christian spirituality.
