How welcome was he at the great meetings of the church,--conferences, associations, conventions. He was usually called upon to give the discourse at the close of the meeting. And it was often a feast to hear him, as he would dwell upon the excellency of the divine attributes, the "exceeding great and precious promises," and the plain and reasonable precepts of the gospel. A prophetic word of good cheer would be spoken by him at such times. He would see, and make others see, the clouds receding, and the clear day opening in the blue and golden sky beyond. However acceptably others had preached before him, the expectation was that somehow his discoursing would give finish and sanction to them all. And it was so. At Barre, Vt., where the General Convention met in 1831, excellent discourses were delivered by able ministers present, and so rich and varied were the topics dwelt upon, that the query was somewhat humorously proposed, "What will Father Ballou have to say after all this?" Judge of our interest and delight when the modest man arose, and in the most quiet way proposed for his text the words of Elihu, in Job, xxxvi. 2: "Suffer me a little, and I will show thee that I have yet to speak on God's behalf." And such a vindication of the character of the gracious Father of all in face of the aspersions cast upon it by his weak and erring children! It was simply electrifying. The late Rev. Theodore Clapp, D. D., of New Orleans, and a minister in the Unitarian Church, once related that, being present in a gathering of Unitarian clergymen in Boston, the conversation turned on the changes which had been effected in the theology of New England, and the question who, of all her great divines, had wrought the most and greatest changes. Of course Channing had the most advocates; but there were some who named Edwards, Emmons, Hopkins, and other doctors of the Orthodox Schools. At last Dr. Clapp, who had remained silent, was appealed to. "Gentlemen," said he, "you have not yet named the man!" "What!" replied all in astonishment, "not named him!" "No, gentlemen, you have not yet named him." "Why, who can it be? We have named every preacher of eminence in New England." "And yet, gentlemen, you have not named _the_ man." "Well, who do you say he is?" With great impressiveness, Mr. Clapp uttered the name. "Hosea Ballou has effected more and greater changes in the theological opinions of the people of New England, than any man dead or living." There was silence for a time, and the discussion was not renewed.[38]
