ution is to be regarded as a treaty between
sovereign States. But how much more does this treaty do for the
abolition of slavery, than that on which we were, a moment since,
bestowing our praise! It imposes a prohibition similar to that in the
supposed treaty between Great Britain and Turkey, so that no slaves have
been allowed to be introduced into the United States since the year
1808. It goes further, and makes ample provision for the abolition and
prevention of slavery in every part of the nation, save these States; so
that the District of Columbia and the national territories can be
cleared forever of slavery, whenever a majority of the parties, bound by
the treaty, shall desire it. And it goes still farther, and clothes this
majority with the power of regulating commerce between the States, and
consequently, of prohibiting their mutual traffic in "the bodies and
souls of men." Had this treaty gone but one step farther, and made an
exception, as it should have done, in behalf of slaves, in the clause
making necessary provision for the return of fugitives held to service
in the States from which they flee, none but those who think it is
fairly held responsible for the twenty years indulgence of the unholy
traffic, would have claimed any thing more from it in relation to
slavery. Now, this instrument, which contains nothing more, bearing on
the subject of slavery, than what I have referred to, and whose pages
are not once polluted with the words "slave" and "slavery," is
abundantly and triumphantly cited, as conclusive authority in favor of
slavery, and against endeavors to abolish it. Whilst we regret, that the
true-hearted sons of freedom in the Convention which formed it, could
obtain no more concessions from the advocates of slavery, let us honor
their sacred memory, and thank God for those they did obtain.

I have supposed it possible, that you might number yourself with those,
who defend slavery on the ground of its alleged conformity with human
laws. It occurs to me, that you may, also, take hope, that slavery is
defensible in the supposed fact, that a considerable share of the
professing Christians, in the free States, are in favor of it. "Let God
be true, but every man a liar." If all professing Christians were for
slavery, yet, if God is against it, that is reason enough why you also
should be against it. It is not true, however, that a considerable share
of our professing Christians are on the side of slave
