Both of these remarkable events, these revolutions shaking nations to their centre, yet polluted with no blood and sullied by no crime, were effected by the salutary agitations of the public mind, first set in motion by the masterspirit of O'Connell, and spreading from around him to every portion of the British empire like the undulations from the disturbed centre of a lake. The Catholic question has been but imperfectly understood in this country. Many have allowed their just disapprobation of the Catholic religion to degenerate into a most unwarrantable prejudice against its conscientious followers. The cruel persecutions of the dissenters from the Romish Church, the massacre of St. Bartholomew's day, the horrors of the Inquisition, the crusades against the Albigenses and the simple dwellers of the Vaudois valleys, have been regarded as atrocities peculiar to the believers in papal infallibility, and the necessary consequences of their doctrines; and hence they have looked upon the constitutional agitation of the Irish Catholics for relief from grieveous disabilities and unjust distinctions as a struggle merely for supremacy or power. Strange, that the truth to which all history so strongly testifies should thus be overlooked,--the undeniable truth that religious bigotry and intolerance have been confined to no single sect; that the persecuted of one century have been the persecutors of another. In our own country, it would be well for us to remember that at the very time when in New England the Catholic, the Quaker, and the Baptist were banished on pain of death, and where some even suffered that dreadful penalty, in Catholic Maryland, under the Catholic Lord Baltimore, perfect liberty of conscience was established, and Papist and Protestant went quietly through the same streets to their respective altars.
