Many great and glorious principles are contained within the constitution of our country. We do not say that it is perfect, but it is perfect so far as it pertains to the rights and privileges of the children of men. But there is a nucleus of a government, formed since that of the United States, which is perfect in its nature, having emanated from a Being who is perfect.
