education and the mechanical arts among the free people of color, and to recover their lost rights. Religious professors, of all denominations, must bear unqualified testimony against slavery. They must not support, they must not palliate it. No slaveholder ought to be embraced within the pale of a christian church; consequently, the churches must be purified 'as by fire.' Slavery in the District of Columbia is sustained in our national capacity: it ought, therefore, to be prostrated at a blow. The clause in the Constitution should be erased, which tolerates, greatly to the detriment and injustice of the non-slaveholding States, a slave representation in Congress. Why should property be represented at the impoverished south, and not at the opulent north? To impair the force of this exposition, the ardent advocates of the Colonization Society will undoubtedly attempt to evade the ground of controversy, and lead uncautious minds astray in a labyrinth of sophistry. But the question is not, whether the climate of Africa is salubrious, nor whether the mortality among the emigrants has been excessive, nor whether the colony is in a prosperous condition, nor whether the transportation of our whole colored population can be effected in thirty years or three centuries, nor whether any slaves have been emancipated on condition of banishment; but whether the doctrines and principles of the Society accord with the doctrines and principles of the gospel, whether slaveholders are the just proprietors of their slaves, whether it is not the sacred duty of the nation to abolish the system of slavery now, and to recognise the people of color as brethren and countrymen who have been unjustly treated and covered with unmerited shame. _This is the question--and the only question._
