I give it to the North and South--to maintain harmony among Christians,
and to secure the integrity of the union of this great people.

This harmony and union can be preserved only by the view presented in this
volume,--_i.e._ that _slavery is of God_, and to continue for the good of
the slave, the good of the master, the good of the whole American family,
until another and better destiny may be unfolded.

The _one great idea_, which I submit to North and South, is expressed in
the speech, first in order, delivered in the General Assembly of the
Presbyterian Church, Buffalo, May 27, 1853. I therein say:--

"Let us then, North and South, bring our minds to comprehend _two
ideas_, and submit to their irresistible power. Let the Northern
philanthropist learn from the Bible that the relation of master and slave
is not sin _per se_. Let him learn that God says nowhere it is sin. Let
him learn that sin is the transgression of the law; and where there is no
law there is no sin, and that _the Golden Rule_ may exist in the
relations of slavery. Let him learn that slavery is simply an evil _in
certain circumstances_. Let him learn that _equality_ is only the highest
form of social life; that _subjection_ to authority, even _slavery_, may,
in _given conditions_, be _for a time_ better than freedom to the slave
of any complexion. Let him learn that _slavery_, like _all evils_, has
its _corresponding_ and _greater good_; that the Southern slave, though
degraded _compared with his master, is elevated and ennobled compared
with his brethren in Africa_. Let the Northern man learn these things,
and be wise to cultivate the spirit that will harmonize with his brethren
of the South, who are lovers of liberty as truly as himself: And let the
Southern Christian--nay, the Southern man of every grade--comprehend that
_God never intended the relation of master and slave to be perpetual_.
