Society, the American Tract Society, and the American Sunday School Union.  Later on in the same century came those two splendid spiritual inventions—­The Young Men’s Christian Association, and the Society of Christian Endeavor.  Sir George Williams, the founder of the one, and Dr. Francis E. Clark, the father of the other, should be commemorated in a pair of twin statues of purest marble, standing with locked arms and upholding a standard bearing the sacred motto:  “One is our Master, even Christ Jesus, and all ye are brethren.”  To no man are we indebted more deeply than to the now glorified Mr. Moody who made Christian fellowship the indispensable feature of all his evangelistic endeavors—­with Brother Sankey leading the grand chorus of united praise.  Union meetings for the conversion of souls and seeking the descent of the Holy Spirit are now as common as the observance of Christmas or of Easter Day.  Personally I rejoice to say that I have been permitted to preach the Gospel in the pulpits of all the leading denominations, not excepting the Episcopalian; and I once welcomed the noble and beloved Bishop Charles P. McIlvaine of Ohio to my Lafayette Avenue Church pulpit, where he pronounced a grand discourse on “The Unity of All Christians in the Lord Jesus Christ.”  If I lived in England I should be heart and soul a nonconformist.  But I can gratefully acknowledge the many kind courtesies which I have received from the clergy of the Established Church.  Once, when in London, I was invited to the annual dinner given by the Lord Mayor to the archbishops and bishops, and I found myself the only American clergyman present.  The Archbishop of Canterbury, when Bishop of London, did me the honor of presiding at a reception given me at Exeter Hall, and whenever I have met the venerable Dr. Temple I have been cheered by his warm-hearted and “democratic” cordiality of manner.  In return for the kindness shown me by my brilliant and scholarly friend, Archdeacon Farrar, I was happy to preside at a reception given him in Chickering Hall.  He had a wide welcome in our land, but it was as the untiring champion of temperance reform that he was especially honored on that evening.  He and Archdeacon Basil Wilberforce are among the leaders in the crusade against the curse of strong drink.  Amid some evil portents and perils to the cause of evangelical religion, one of the richest tokens for good is this steady increase of interdenominational fellowship.  For organic unity we need not yet strive; it is enough that all the regiments and brigades in Christ’s covenant hosts march to the same music, fight together under the same standard of Calvary’s Cross, and press on, side by side, and shoulder to shoulder, to the final victory of righteousness and truth and human redemption.
