alternative, the proceeding would be by "suit at Common Law," with Trial by Jury; and it would be the solemn duty of the court, according to all the forms and proper delays of the Common Law, to try the case on the evidence, strictly to apply all protecting rules of evidence, and especially to require stringent proof, by competent witnesses under cross-examination, that the person claimed was _held_ to service, that his service was _due_ to the claimant, that he had _escaped_ from the State where such service was due, and also proof of the _laws_ of the State under which he was held. _Still further, to the Courts of each State must belong the determination of the question, to what class of persons, according to just rules of interpretation, the phrase "person held to service or labor" is strictly applicable._ Such is this much debated provision. The Slave States, at the formation of the Constitution, did not propose, as in cases of Naturalization and Bankruptcy, to empower the National Government _to establish an uniform rule_ for the rendition of fugitives from service, _throughout the United States_; they did not ask the National Government to charge itself in any way with this service; they did not venture to offend the country, and particularly the Northern States, by any such assertion of hateful pretension. They were content, under the sanctions of compact, in leaving it to the public sentiment of the States. There, I insist, it must remain. * * * * * Mr. President, I have occupied much time; but the great subject still stretches before us. One other point yet remains, which I must not leave untouched, and which justly belongs to the close. The Slave Act violates the Constitution, and shocks the Public Conscience. With modesty, and yet with firmness, let me add, Sir, it offends against the Divine Law. No such enactment is entitled to support. As the throne of God is above every earthly throne, so are his laws and statutes above all the laws and statutes of man. To question these is to question God himself. But to assume that human laws are beyond question is to claim for their fallible authors infallibility. To assume that they are always in conformity with the laws of God is presumptuously and impiously to exalt man even to equality with God. Clearly, human laws are not always in such conformity; nor can they ever be beyond question from each individual. Where the conflict is open, as if Congress should command the perpetration of murder, the office of conscience as final arbiter is undisputed. But in every conflict the same queenly office is hers. By no earthly power can she be dethroned. Each person, after anxious examination, without haste, without passion, solemnly for himself must decide this great controversy. Any other rule attributes infallibility to human laws, places them beyond question, and degrades all men to an unthinking, passive obedience.
