I’ve been working my way through A Treatise on Atonement by Hosea Ballou, the great Universalist minister and theologian of the early nineteenth century. I like Ballou’s commitment to the use of common sense and reason in religion, as exemplified in passages like this one:
We feel our own imperfections; we wish for every one to seek with all his might after wisdom; and let it be found where it may, or by whom it may, we humbly wish to have it brought to light, that all may enjoy it; but do not feel authorized to condemn an honest inquirer after truth, for what he believes different from a majority of us.
This could be a central motto for religious liberals.
