Other than that of our one and only proclaim and commanded Christ word in our own free American Republic. Based wholly upon it. Both of which I understand them pledge and bind every man of us to grant all mankind equal rights, privileges, and duties according to there's several abilities and deserts before God and the law and to require of them only to do by all others as they would be done. By if this is not the entire whole of both law and gospel all the earth, and all the heavens above earth, I never knew, and never heard, or believe anything intelligible about it and have never been born into any fixed belief on the subject. But if this is the substantial truth of the whole matter, that I am and always have been a native born abolitionist. Though I never signed any sort of church creed, sold myself out to any sort of religious or abolition society, took no interesting running slaves off to Canada, because they were not needed there, but needed here to help us face the music around here. Besides to do or say anything behind one's back was distasteful to me”.
