The strongest of those of a spiritual and ecclesiastical nature, consisted in the unity of the great religious denominations, all of which originally embraced the whole Union. All these denominations, with the exception, perhaps, of the Catholics, were organized very much upon the principle of our political institutions. Beginning with smaller meetings, corresponding with the political divisions of the country, their organization terminated in one great central assemblage, corresponding very much with the character of Congress. At these meetings the principal clergymen and lay members of the respective denominations from all parts of the Union, met to transact business relating to their common concerns. It was not confined to what appertained to the doctrines and discipline of the respective denominations, but extended to plans for disseminating the Bible--establishing missions, distributing tracts--and of establishing presses for the publication of tracts, newspapers, and periodicals, with a view of diffusing religious information--and for the support of their respective doctrines and creeds. All this combined contributed greatly to strengthen the bonds of the Union. The ties which held each denomination together formed a strong cord to hold the whole Union together, but, powerful as they were, they have not been able to resist the explosive effect of slavery agitation. The first of these cords which snapped, under its explosive force, was that of the powerful Methodist Episcopal Church. The numerous and strong ties which held it together, are all broken, and its unity is gone. They now form separate churches; and, instead of that feeling of attachment and devotion to the interests of the whole church which was formerly felt, they are now arrayed into two hostile bodies, engaged in litigation about what was formerly their common property. The next cord that snapped was that of the Baptists--one of the largest and most respectable of the denominations. That of the Presbyterian is not entirely snapped, but some of its strands have given way. That of the Episcopal Church is the only one of the four great Protestant denominations which remains unbroken and entire. The strongest cord, of a political character, consists of the many and powerful ties that have held together the two great parties which have, with some modifications, existed from the beginning of the Government. They both extended to every portion of the Union, and strongly contributed to hold all its parts together. But this powerful cord has fared no better than the spiritual. It resisted, for a long time, the explosive tendency of the agitation, but has finally snapped under its force--if not entirely, in a great measure. Nor is there one of the remaining cords which has not been greatly weakened. To this extent the Union has already been destroyed by agitation, in the only way it can be, by sundering and weakening the cords which bind it together.
