Whose Body?

Caryl Johnston quotes Cardinal Ratzinger: “. . . obeying Christ means obeying his body, obeying him in his body . . . .” I do not have the original text, from Pilgrim Fellowship of Faith: The Church as Communion. It seems that here “his body” means the Church, Christ’s mystical body, not his physical body or the Eucharist. Cardinal Ratzinger must not be writing of personal obedience to Jesus; otherwise he would have said ”obeying his body, obeying him in our [or one’s] body.” Or so I think without consulting the text.
