Petitioner Hosanna-Tabor Evangelical Lutheran Church and School is a member congregation of the Lutheran Church–Missouri Synod. The Synod classifies its school teachers into two categories: “called” and “lay.” “Called” teachers are regarded as having been called to their vocation by God. To be eligible to be considered “called,” a teacher must complete certain academic requirements, including a course of theological study. Once called, a teacher receives the formal title “Minister of Religion, Commissioned.” “Lay” teachers, by contrast, are not required to be trained by the Synod or even to be Lutheran. Although lay and called teachers at Hosanna-Tabor generally performed the same duties, lay teachers were hired only when called teachers were unavailable.
After respondent Cheryl Perich completed the required training, Hosanna-Tabor asked her to become a called teacher. Perich accepted the call and was designated a commissioned minister. In addition to teaching secular subjects, Perich taught a religion class, led her students in daily prayer and devotional exercises, and took her students to a weekly school-wide chapel service. Perich led the chapel service herself about twice a year.
