Ferdinand was as energetic as he had previously proved himself inflexible and persevering. In person he visited Munich, the capital of Bavaria, that he might more warmly interest in his favor Maximilian, the illustrious and warlike duke. The emperor made him brilliant promises, and secured his cordial cooeperation. The Duke of Bavaria, and the Elector of the Palatinate, were neighbors and rivals; and the emperor offered Maximilian the spoils of the Palatinate, if they should be successful in their warfare against the newly elected Bohemian king. Maximilian, thus persuaded, placed all his force at the disposal of the emperor. The Elector of Saxony was a Lutheran; the Elector Palatine a Calvinist. The Lutherans believed, that after the consecration of the bread and wine at the sacramental table, the body and blood of Christ were spiritually present with that bread and wine. This doctrine, which they called _consubstantiation_, they adopted in antagonism to the papal doctrine of _transubstantiation_, which was that the bread and wine were actually transformed into, and became the real body and blood of Christ. The difference between the Calvinists and the Lutherans, as we have before mentioned, was that, while the former considered the bread and wine in the sacraments as _representing_ the body and the blood of Christ, the latter considered the body and the blood as spiritually present in the consecrated elements. This trivial difference divided brethren who were agreed upon all the great points of Christian faith, duty and obligation. It is melancholy, and yet instructive to observe, through the course of history, how large a proportion of the energies of Christians have been absorbed in contentions against each other upon shadowy points of doctrine, while a world has been perishing in wickedness. The most efficient men in the Church on earth, have had about one half of their energies paralyzed by contentions with their own Christian brethren. It is so now. The most energetic men, in pleading the cause of Christ, are often assailed even more unrelentingly by brethren who differ with them upon some small point of doctrine, than by a hostile world.
