Book excerpt: "When J.A.O. Preus was elected President of the three-million-member Lutheran Church-Missouri Synod in 1969, he was virtually unknown outside his own denomination. Most observers were surprised and even the experts did not know what to expect. What they got was a headline-making dispute between Preus and John Tietjen, head of the Synod's prestigious Concordia Seminary; a seminary-in-exile training ministers without official sanction; and finally a Lutheran civil war that has divided congregations and even members of the same family."--Book jacket.
