We must set our faces against allowing congregations to embrace but one social class, or several easily combined social strata in the community. In our American towns the Protestant communions are separated more by social caste than by religious conviction. People attend the church where they find "their kind." Poor people do not feel themselves at home, even spiritually, among the well-to-do, and the children of comfortable homes are not permitted to go to the same Sunday School with the children of the tenements. Class lines are as apparent, and almost as divisive, in our churches as anywhere else. The Church of Christ under such circumstances ceases to be a unifying factor in society; its teaching of brotherhood becomes a mockery. In every community there will be found some entirely unchurched social group; and the churches themselves will be impoverished by the absence of the spiritual appreciations to be found most developed in persons of that stratum. Our denominational divisions tend to accentuate our social divisions. Church unity, lessening the number of congregations in a locality, would help to make the churches that remained more socially inclusive. Meanwhile the "one class church," in any but the very rare homogeneous community, ought to realize that, whatever Christian service it may render, it is all the while doing the cause of Christ a great disservice, and is in need of a radical reorganization and an equally radical spiritual renewal into its Lord's wider sympathies. Personally we must rigidly examine ourselves and test our right to be considered members of the Body of Christ. There are some New Testament evidences of the Spirit that we must still demand of ourselves. One is loyal obedience to Jesus: "No man can say, Jesus is Lord, but in the Holy Spirit." A second is filial trust in God: "Because ye are sons, God sent forth the Spirit of His Son into our hearts, crying, Abba, Father." A third is self-devoting love akin to that shown on Calvary: "The fruit of the Spirit is love;" "By this shall all men know that ye are My disciples, if ye have love one to another." And if the Spirit is within us, He is eager to work through us. We may be quenching Him by laziness, by timidity, by preoccupation. We are of the Body of Christ only as we are "members each in his part."
