The First Congress: 1790, Enter The Quakers

from Great Debates in American History, by United States Congress, Great Britain Parliament, Marion Mills Miller, published 1913, Current Literature Publishing Company:

That the questions connected with slavery had not been settled by the compromises on the subject in the Constitution was shown by a petition presented to Congress in its first session, praying for the abolition of the slave trade.
On February 11, 1790, Thomas Fitzsimons [Pa.] presented a petition from the Yearly Meeting in 1789 of Friends (Quakers) in Pennsylvania, New Jersey, Delaware, and western parts of Maryland and Virginia praying:
That Congress might make “sincere and impartial inquiry whether it be not an essential part of the duty of your exalted station to exert upright endeavors, to the full extent of your power, to remove every obstruction to public righteousness, which the influence or artifice of particular persons, governed by the narrow, mistaken views of self-interest, has occasioned, and whether, notwithstanding such seeming impediments, it be not in reality within your power to exercise justice and mercy, which, if adhered to, we cannot doubt must produce the abolition of the slave trade.”
In their preamble the petitioners stated that a similar memorial had been made to Congress in 1783, but that,
“. . . though the Christian rectitude of the concern was by the delegates generally acknowledged, yet, not being vested with the powers of legislation, they declined promoting any public remedy against the gross national iniquity of trafficking in the persons of fellowmen; but divers of the legislative bodies of the different States on this continent have since manifested their sense of the public detestation due to the licentious wickedness of the African trade for slaves, and the inhuman tyranny and blood-guiltiness inseparable from it; the debasing influence whereof most certainly tends to lay waste the virtue and, of course, the happiness of the people.”
Mr. John Lawrence also presented an Address from the Society of Friends, in the city of New York, in which they set forth their desire of cooperating with their Southern brethren in their protest against the slave trade.
It was moved to refer the petitions to a committee. This was opposed by James Jackson [Ga.], as diverting the attention of the members from the great question before them to one of “questionable policy,” and which Congress could take up without advisers, “because the Constitution expressly mentions all the power they can exercise on the subject.”
In the debate which ensued on the subject the leading speakers in behalf of committing the petitions were James Madison [Va.], Thomas Hartley [Pa.], and Roger Sherman [Conn.]; against committing it, Michael J. Stone [Md.], James Jackson [Ga.], William L. Smith [S. C.], and Thomas T. Tucker [S. C.].
