This message, delivered for the Festival of Saints Peter & Paul, addresses the Office of the Keys, the authority of the Pastoral Office (or Office of the Holy Ministry). Many Protestants believe that pastors' only authority is human-bestowed and can be taken away by human institutions, but the Biblical doctrine is that Christ Himself appointed men to be pastors and gave them authority. Dr. Zeile's exposition is accompanied by the noted hymn "By All Your Saints in Warfare for all Thy Saints at Rest,"  and station collects for each of the saints celebrated.
