expressions of impatience and petulance represent the feelings of very few. Who is it that always speaks first? The angry man, and it comes out at once; but the wise man keeps it in till afterwards; and it will not be long before you will find, that whatever you say in a Christian spirit will be responded to on the other side of the water. Now, I believe our churches have neglected their duty on this subject, and are still neglecting it. Many do not seem to know what their duty is. Yet I believe them to be good, conscientious men, and men who will do their duty when they know what it is. Take, for example, the American Board of Foreign Missions. There are not better men, or more conscientious men, on the face of the earth, or men more sincerely desirous of doing their duty; yet, in some things, I believe they are mistaken. I think it would be better to throw over the very few churches connected with the Board which are slaveholding, than to endeavor to sustain them, and to have all this pressure of responsibility still upon them. But yet they are pursuing the course which they conscientiously think to be right. Christian admonition will not be lost upon them.[H] I will say the same of the American Home Missionary Society. They have little to do with slavery, as I have already remarked. Many think they ought not to say any thing upon the subject, because they cannot do so without weakening their influence. But then this question comes: If good men do not speak, who will?--[Hear, hear!]--and, as our Savior said in regard to the children that shouted, Hosannah, 'If these should hold their peace, the stones would immediately cry out.' It is in consequence of their silence that stones have begun to cry out, and they rebuke the silence and apathy of good men; and this is made an argument against religion, which has had effect with unthinking people; so I think it absolutely necessary that men in the church, on that very ground, should speak out their mind on this great subject at whatever risk--[cheers]--and they must take the consequences. In due time God will prosper the right, and in due time the fetters will fall from every slave, and the black man will have the same privileges as the white.
