Until Luther led the great reformatory schism in the sixteenth century, all historians, crude and unscientific though much of their work was, recognised the necessary union of political and ecclesiastical history. The Venerable Bede began his celebrated history not with the coming of Abbot Augustine and his monks, but with the landing of Cæsar and his Roman cohorts. As modern civilisation crept over western Europe and crossed the mighty deep to Columbia's shores, carrying with it the revolutionising Teutonic conception of the national state with its new duties and relationships, the tendency was to magnify the political and social sides of history at the expense of the religious. The hatreds and misunderstandings of the Reformation, though doing something to rectify the "orthodox" history of the old Church, really put members of the old organisation wholly on the defensive, and checked for centuries anything like a genuinely sympathetic and scientific study of the old Church by Protestant historians. With Neander, that sympathetic Christian of Jewish descent, and the scholarly Gieseler, a new era opened. The growing doctrine of the separation of Church and state accentuated the breach between political and religious history. The early crude conception of specialisation also separated sacred from profane history, and turned the former over wholly to the theologian. Secular historians took the position of Napoleon when invited to enter the Holy City: "Jerusalem does not enter into the line of my operations." At last the Church historian and the civic historian have joined hands, and look each other in the face. They see that their aim is essentially common: to know the truth about the past. This search for truth for its own sake is purely modern--almost contemporaneous. Formerly, history was written to justify or disprove some theory of political or ecclesiastical polity, or to glorify some dynasty, sect, party, or hero, or to vindicate some hypothesis or set of ideas. The historian was not a searcher for truth, but a lawyer with a cause to plead. It is generally realised now that the historian, whether he deals with the state, the Church, society, education, or industry, is working an important part of the field of general history. A knowledge of each one of these institutions is necessary to supplement and explain any or all of the others.
