The discussions which I had with sundry individuals who were acquainted with the subject led me to study the Constitution with greater care and deeper interest than ever before. It seemed to me that we owed it to the memory of those venerated men whose names are conspicuous in the early history of our Republic--those men who so solemnly pledged “their lives, their fortunes, and their sacred honor” to the cause of freedom and the inalienable rights of man--to exonerate them, if we fairly could, from the awful responsibility that was laid upon them by those who insisted that they _guaranteed_ to the Southern States the unquestioned exercise of their assumed right to enforce the _enslavement_ of one sixth part of the population of the land, many of whom had shared with them in all the hardships and perils of their struggles for independence. It seemed to me that every article of the Constitution usually quoted as intended to favor the assumptions of slaveholders admitted of an opposite interpretation, and that we were bound by every honorable and humane consideration to prefer that interpretation. The conclusions to which I was brought on this subject I gave some time afterwards in the _Antislavery Magazine_ for 1836. But the publication of the “Madison Papers,” in which was given the minutes, debates, etc., of the convention which framed the Constitution, I confess, disconcerted me somewhat. I could not so easily maintain my ground in the discussions which afterwards agitated so seriously the Abolitionists themselves,--some maintaining that the Constitution was, and was intended to be, proslavery; others maintaining that it was antislavery. It seemed to me that it might be whichever the people pleased to make it. I rejoice, therefore, with joy unspeakable that the question is at length practically settled, though by the issue of our late awful war.
The coming of George Thompson to our country in the fall of 1834, and his thrilling eloquence respecting our great national iniquity, awakened general attention to the subject, and caused more excitement about it than before. He came, as it were, a missionary from the philanthropists of Great Britain to show our people their transgression. The politicians tried to get up the public indignation against him as “a foreign emissary interfering with our political affairs.” The religionists resented his coming as an impertinence, though _they_ were much engaged in sending missionaries to the heathen to reclaim them from sins no more heinous than ours. Nevertheless, the people flocked to hear him, and many were converted. The demand for antislavery lectures came from all parts of New England, and from many parts of the Middle and Western States. A great work was to be done. The fields were whitening to the harvest, but the laborers were few. I therefore accepted the renewed invitation of the Massachusetts Antislavery Society to become its General Agent and Corresponding Secretary, and removed to Boston early in the spring of 1835. Many of my nearest relatives and dearest friends received me kindly, but with sadness. They feared I should lose my standing in the ministry and become an outcast from the churches. For a while it seemed as if their apprehensions were not groundless. None of the Boston ministers, excepting Dr. Channing, welcomed me. Dr. Follen, Dr. Ware, Jr., and Dr. Palfrey were then resident in Cambridge; Mr. Pierpont was in Europe. James Freeman Clarke had not left Louisville, and Theodore Parker was a student in the Divinity School. I was indeed soon made to feel that I was not in good repute. Dr. Ware, who had charge of the Hollis Street pulpit in the absence of the pastor, invited me to supply it, if I found I could do so consistently with my new duties. I engaged for two Sundays. But at the close of the first, one of the chief officers of the church waited upon me, by direction of the principal members, and requested me not to enter their pulpit again, assuring me, if I should do so, that a dozen or more of the prominent men with their families would leave the house. Of course I yielded that, and I was not invited into any other pulpit in the city, excepting Dr. Channing’s, during the fifteen months that I resided there.
