The two Theologies at the present time which stand opposed to each other here are not Calvinism and Armenianism, not Trinitarianism and Unitarianism, not Naturalism and Supernaturalism. But they are the Theology of discouragement and fear on one side, that of courage and hope on the other. The one thinks men must be driven to God by terror: the other seeks to attract them by love. The one has no faith in man, believes him wholly evil, believes sin to be the essential part of him. The other believes reason a divine light in the soul, and encourages it to act freely; trusts in his conscience enlightened by truth, and appeals to it confidently; relies on his heart, and seeks to inspire it with generous affections and disinterested love. That this Theology of faith is to triumph over that of fear who can doubt? All the best thought, the deepest religion, the noblest aspiration of the age, flows in this direction. Whether our handful of Unitarian Churches is ever to become a great multitude or not, I do not know; but I am sure that the spirit which inspired the soul of Channing is to lead the future age, and make the churches which are to be. It is not now a question of Unity or Trinity, but something far deeper and much more important. While endeavoring to settle the logical terms of Christ's divinity and humanity, we have been led up higher to the sight of the Divine Father and the Human Brotherhood. Like Saul, the son of Kish, we went out to seek our father's asses, and have found a kingdom. We have recently been told about a Boston Theology. If there is any thing which deserves to be called a Boston Theology it is this doctrine of courage and hope. For it is shared by all the leading minds of all Protestant denominations in this city. Whatever eminent man comes here, no matter what he was when he came, finds himself, ere long, moving in this direction. The shackles of tradition and formality fall from his limbs, his eyes open to a new light; and he also becomes the happy herald of a new and better day.
