Marion Josiah Hatchett (1927–2009) was an Episcopal priest, scholar, and one of the primary liturgists who shaped the 1979 Book of Common Prayer.
Desiring to further his education, he moved from Charlestown back to Sewanee, Tennessee in 1965 in order to pursue a Master of Sacred Theology degree, which he received in 1967.
He served as chairman of the committee which produced The Book of Occasional Services, 1979 as well as a member of the Episcopal Church's General Board of Examining Chaplains (1988–1994).
He is also the author of Sanctifying Life, Time and Space: An Introduction to Liturgical Study (1976), A Manual for Clergy and Church Musicians (1980), The Making of the First American Book of Common Prayer (1982), and several journal articles.
Even after his retirement he remained in Sewanee, playing an active role at The School of Theology, continuing to teach at an adjunct level and open his home to students.
