Good Friday was observed by the people of New England as an annual fast-day, to humble themselves on account of their national sins. It seemed, somewhat to our inconvenience, to be literally and very rigidly observed in the circle in which we moved. On that day all ministers are at liberty to preach upon politics. Accordingly, my friend Mr. Sawyer took for his text Isaiah lviii. 6: "Is not this the fast that I have chosen? to loose the bands of wickedness, to undo the heavy burdens, and to let the oppressed go free, and that ye break every yoke?" He touched upon the war with Mexico, but dwelt chiefly on the subject of slavery in America. His remarks were, however, too much mingled with party politics to make the church uncomfortable. In the afternoon I heard Mr. Dutton, in the North Church. His text was Neh. ii. 3, and his subject _Patriotism_. The existing war occupied much of his attention, and was strongly and unsparingly denounced. The maxim--too frequently heard at that time in the United States--"Our country, right or wrong," he shattered to atoms. Defensive war, however, he justified. He dwelt powerfully on the responsibility connected with the exercise of the elective franchise, and urged the duty of voting, at all times, not blindly and for party purposes, but intelligently, honestly, and piously. Exceptions might perhaps be taken by some to his views on defensive war; otherwise the discourse was excellent and seasonable. At the close of the service, we went, in accordance with previous arrangements, to be his guests for a few days. In the evening I attended a Congregational church of coloured people. The place was exceedingly neat and clean. The minister, the Rev. Mr. Beman (himself a coloured man), gave out the well-known hymn-- "Come we that love the Lord, And let our joys be known," &c., which was sung beautifully. He then offered up a very judicious, sensible, and pious prayer. The meeting was one of a series of revival meetings. A large number professed to have been converted; but, such were the care and caution exercised, none of them had been admitted into the fellowship of the church. Mr. Beman was so prudent, unassuming, and devout, that I could not resist the inclination to go up, introduce myself, and give a short address. Most cordial was my reception, and great my enjoyment. At the close, one and another were introduced to me as having made their escape from Southern slavery, under circumstances painfully affecting; and they would not let me go without a promise that I would preach to them on the following Sabbath morning.
