I have previously remarked that the manners of the people may be considered as one of the general causes to which the maintenance of a democratic republic in the United States is attributable. I here use the word _manners_, with the meaning which the ancients attached to the word _mores_; for I apply it not only to manners, in their proper sense of what constitutes the character of social intercourse, but I extend it to the various notions and opinions current among men, and to the mass of those ideas which constitute their character of mind. I comprise, therefore, under this term the whole moral and intellectual condition of a people. My intention is not to draw a picture of American manners, but simply to point out such features of them as are favorable to the maintenance of political institutions. * * * * * RELIGION CONSIDERED AS A POLITICAL INSTITUTION, WHICH POWERFULLY CONTRIBUTES TO THE MAINTENANCE OF THE DEMOCRATIC REPUBLIC AMONG THE AMERICANS. North America peopled by Men who professed a democratic and republican Christianity.--Arrival of the Catholics.--For what Reason the Catholics form the most democratic and the most republican Class at the present Time. Every religion is to be found in juxtaposition to a political opinion, which is connected with it by affinity. If the human mind be left to follow its own bent, it will regulate the temporal and spiritual institutions of society upon one uniform principle; and man will endeavor, if I may use the expression, to harmonize the state in which he lives upon earth, with the state he believes to await him in heaven. The greatest part of British America was peopled by men who, after having shaken off the authority of the pope, acknowledged no other religious supremacy: they brought with them into the New World a form of Christianity, which I cannot better describe, than by styling it a democratic and republican religion. This sect contributed powerfully to the establishment of a democracy and a republic; and from the earliest settlement of the emigrants, politics and religion contracted an alliance which has never been dissolved. About fifty years ago Ireland began to pour a catholic population into the United States; on the other hand, the catholics of America made proselytes, and at the present moment more than a million of Christians, professing the truths of the church of Rome, are to be met with in the Union. These catholics are faithful to the observances of their religion; they are fervent and zealous in the support and belief of their doctrines. Nevertheless they constitute the most republican and the most democratic class of citizens which exists in the United States; and although this fact may surprise the observer at first, the cause by which it is occasioned may easily be discovered upon reflection.
