George Willis Cooke,
Unitarianism in America: A History of its Origin and Development
“ Especially do we feel that the denomination which takes for its motto Liberty, Holiness and Love should be foremost in opposing this system. More than others we have contended for three great principles,--individual liberty, perfect righteousness, and human brotherhood. All of these are grossly violated by the system of slavery. We contend for mental freedom; shall we not denounce the system which fetters both mind and body? We have declared righteousness to be the essence of Christianity; shall we not oppose the system which is the sum of all wrong? ”
