American slaveholders must prepare, not only to be excluded from the communion of British Christians, but peremptorily driven from the platform of every philanthropic association. Let them be hemmed in on every side. Let them be placed beyond the pale of respectability, and, standing out separated, alone in their infamy, let the storm gather over them, and its hottest bolts descend. Our justification is ample:-the slaveholder is a man-stealer.
