Scioppius, in his Alarm Trumpet to the Holy War, and a hundred others declared that all heresies and heretics were now to be extirpated, the one true church to be united and re-established, and that the only road to such a consummation was a path of blood.
The Lutheran preachers, on the other hand, obedient to the summons from Dresden, vied with each other in every town and village in heaping denunciations, foul names, and odious imputations on the Catholics; while the Calvinists, not to be behindhand with their fellow Reformers, celebrated the jubilee, especially at Heidelberg, by excluding Papists from hope of salvation, and bewailing the fate of all churches sighing under the yoke of Rome.
And not only were the Papists and the Reformers exchanging these blasts and counterblasts of hatred, not less deadly in their effects than the artillery of many armies, but as if to make a thorough exhibition of human fatuity when drunk with religious passion, the Lutherans were making fierce paper and pulpit war upon the Calvinists.

Especially Hoe, court preacher of John George, ceaselessly hurled savage libels against them.

In the name of the theological faculty of Wittenberg, he addressed a "truehearted warning to all Lutheran Christians in Bohemia, Moravia, Silesia, and other provinces, to beware of the erroneous Calvinistic religion." He wrote a letter to Count Schlick, foremost leader in the Bohemian movement, asking whether "the unquiet Calvinist spirit, should it gain ascendency, would be any more endurable than the Papists.

Oh what woe, what infinite woe," he cried, "for those noble countries if they should all be thrust into the jaws of Calvinism!" Did not preacher Hoe's master aspire to the crown of Bohemia himself?
Was he not furious at the start which Heidelberg had got of him in the race for that golden prize?
Was he not mad with jealousy of the Palatine, of the Palatine's religion, and of the Palatine's claim to "hegemony" in Germany?
Thus embittered and bloodthirsty towards each other were the two great sections of the Reformed religion on the first centennial jubilee of the Reformation.

Such was the divided front which the anti-Catholic party presented at the outbreak of the war with Catholicism.
Ferdinand, on the other hand, was at the head of a comparatively united party.
