(The ministerial exception applied to a work practice apprentice at defendant’s Zen Buddhist center. Even though plaintiff performed mostly menial work, the work itself was an essential component of Zen training, and he therefore played a role in carrying out the Center’s mission. Among other things, plaintiff was responsible for assisting with rituals, participating in meditations and services, cleaning the temple, attending talks and classes, and performing doan ryo ceremonial tasks like ringing bells and cleaning altars. Precedent foreclosed the argument that only teachers and faith leaders qualify for the ministerial exception.)
