The next Puritan of prominence who enlisted among the helpers of the
African slaves was Chief Justice Sewall, of Massachusetts. In 1701
he stirred his section by publishing his _Selling of Joseph_, a
distinctly anti-slavery pamphlet, based on the natural and inalienable
right of every man to be free.[1] The appearance of this publication
marked an epoch in the history of the Negroes. It was the first direct
attack on slavery in New England. The Puritan clergy had formerly
winked at the continuation of the institution, provided the masters
were willing to give the slaves religious instruction. In the _Selling
of Joseph_ Sewall had little to say about their mental and moral
improvement, but in the _Athenian Oracle_, which expressed his
sentiments so well that he had it republished in 1705,[2] he met more
directly the problem of elevating the Negro race. Taking up this
question, Sewall said: "There's yet less doubt that those who are of
Age to answer for themselves would soon learn the Principles of our
Faith, and might be taught the Obligation of the Vow they made in
Baptism, and there's little Doubt but Abraham instructed his Heathen
Servants who were of Age to learn, the Nature of Circumcision before
he circumcised them; nor can we conclude much less from God's own
noble Testimony of him, 'I know him that he will command his Children
and his Household, and they shall keep the Way of the Lord.'"[3]
Sewall believed that the emancipation of the slaves should be promoted
to encourage Negroes to become Christians. He could not understand
how any Christian could hinder or discourage them from learning the
principles of the Christian religion and embracing the faith.
