The author of this lecture, who has been my personal friend for thirty years, and who wrote to me on the occasion of its publication to express his hope that it might not interrupt our friendship, and all the Protestants who may peruse these pages, especially those who know me, will admit that I am both competent to explain what Catholic doctrine is, and incapable of practising any dissimulation on the subject. Those who knew F. Baker, or who may learn to know him from reading this volume, will also acknowledge that his high-toned mind was incapable of yielding to any system of driveling superstition, and his chivalrous spirit of descending to any system of artful deception by paltering with words in a double sense. I ask them, therefore, not, to accept Catholic doctrine as true on our authority, but simply to believe that the testimony I give as to the doctrine we have embraced and preached, and our views and intentions in giving missions, is true; and that the doctrine, contained in the discourses of this volume, is a veritable exposition of the true Catholic faith. {132} The missions were commenced and have been carried on for the purpose of benefiting the Catholic people.

Not a word of instruction or direction as to the manner of preaching, or the end to be aimed at in our labors, has ever been given by authority, but the movement has been the spontaneous act of the few individuals who began it. It is our desire, as it must be that of every Catholic priest, to bring as many persons as possible to the Catholic faith and into the bosom of the Catholic Church. We intend, therefore, to make use of all the means and opportunities in our power to present the faith and the Church to our non-Catholic countrymen, and to promote as much as possible the conversion of the American people. The Catholic Church has the mission to convert the whole world, and intends to fulfil it; and any Catholic priest who does not endeavor to do his share of the work, is recreant to the high obligations of his office. We intend to do our part, however, in promoting this great end, not by artifice or dissimulation, not by secret intrigues or plots, by fraud or violence, by undermining or attacking the civil and religious liberty enjoyed by all our citizens in common, but by argument and persuasion, by exhibiting the Church in her beauty, by prayer and good example, and by the grace of God: We have no
