Admitting all this, however, these intellectual changes are not the principal cause of the enfeeblement of the church. These changes, however we may regard them, have affected but a small minority of the members of our churches; the great majority of them continue to hold substantially the same theological opinions that they have always held. The trouble with the church is not chiefly a lack of faith in the creeds, it is a lack of faith in Christ. And it is not a lack of faith in the metaphysical theories of Christ's person, but a lack of faith in the truth of his teaching. It is an unbelief in which the most orthodox people are quite as much involved as those who are considered heretics. The central question is not, after all, what we think about the nature of Christ. There is good reason to believe that none of the twelve apostles held, during the life of our Lord, opinions which would be regarded as orthodox concerning his person. They believed that he was a great Prophet, a revealer of God; nay, they believed that he was the Messiah, the long promised King, who was to set up his kingdom in this world. Of this they had no doubt. This was the belief that Jesus himself sought to fasten in their minds; and when he had drawn from Simon Peter a confession of this faith he cried out, "Blessed art thou, Simon son of John; for flesh and blood hath not revealed it unto thee, but my Father which is in heaven." It was this faith in him as Lord and Ruler of men, as the Founder in this world of a kingdom of righteousness and peace, on which, as he declared, his church should be builded. Such faith as this these twelve men had. They would have found it difficult, probably, to assent to the Nicene Creed or the Athanasian Creed; but they believed in Jesus as Lord and King, and they believed every word of his Magna Charta found in the Sermon on the Mount; and they were ready to do what they could to establish that kingdom in this world. It is just here that the faith of the church is lacking. It believes the Nicene Creed, but it does not believe the Sermon on the Mount. It believes what men have said about Christ; it does not believe what Christ himself said. It does not accept the practical rule of life which he has laid down. It does not believe that the Golden Rule is workable in modern life. It does not believe that it is feasible to love our neighbors as ourselves. It does not believe in the kingdom of heaven as a present possibility. It expects that Christ will come, by and by, in person, with miraculous power, to revolutionize society, and that after that it will be practicable to follow the law of love, in all our human relations; but, for the present, we must let the law of competition control all our practical affairs.
