We have the motive of this reason in the fact that a Presbyterian preacher of Huntington had thought fit to assail and calumniate the Catholic Church as an institution dangerous to the country and to its liberties. Gallitzin immediately took up the pen in answer, and the necessities of the controversy turned him into a polemica writer. There are in America, no less than in other countries, fanatical sectarians who follow their congenial instincts in sounding the alarm-cry whenever the Catholic Church marks out new limits of lawful conquest. In this instance, the state was declared to be in peril; but Gallitzin lost no time in confounding the slanderers of Catholicity by the publication of his "Defense of Catholic Principles," which appeared in Pittsburgh in the year 1816. This work, written in English--for the author wielded the English with as much facility as he did the German language, his mother tongue--was, on both shores of the ocean, greeted with success. Father Lemcke made a German translation of the "Defense of Catholic Principles," of which two editions were published in Ireland and four in the United States, ranking "in popularity with 'Cobbett's History of the Reformation,' to which it bears a resemblance in putting a probing finger on the plague-spot of Protestantism." The start being once made, Gallitzin followed up his first work with other publications of an entirely practical character, directed against certain prevalent moral diseases of the day, which mark an epoch in the monography of American ideas. Gallitzin was perfectly familiar with the mode of treatment of the feverish exuberance of American notions, and he handled them with all the cautious skill of a prudent practitioner. Everything which he published on these matters, both in elucidation of his views and as a muniment against the evils which he denounced, is written in the winning and popular style which was familiar to his pen. Hence his works were crowned with success, even amongst the higher classes of society. "Gallitzin's publications," says his biographer, "exerted an immense influence in the period when he lived, but especially so among the humbler members of the community, for whom they were destined. They were found, and they may still be found, in the form of unpretending pamphlets, in the hotels and steamboats of the West, for he had them printed at his own expense and distributed as the Protestant colporteurs disseminate their Bibles and tracts. The curiosity of the readers enlarged their circulation everywhere; and I myself have found them as perfectly thumbed as any spelling-book in spots where I never dreamed of meeting with them."
