The church, as thus defined, has no uniform and authoritative creed, and no ruling officers or assemblies who have a right to speak for it; it is difficult, therefore, to make any definite statements about it. It is possible, nevertheless, to think of all these variously organized groups of people as belonging to one body. In some very important matters they are united. They all believe in one God, the Father Almighty; they all bear the name of Christ; they all acknowledge him as Lord and Leader; they all accept the Bible as containing the truth which they profess to teach. The things in which they agree are, indeed, far more important than the things in which they differ, and it is our custom often to speak of this entire body of Christian disciples as "the church," forgetting their differences and emphasizing their essential unity. This is the meaning which will be given to "the church" in these discussions. The church is concerned with religion. As the interest of the state is politics, of the bank finance, of the school education, so the interest of the church is religion. Religion organizes the church, and the church promotes religion. Religion is a fact of the first magnitude. We sometimes hear ministers complaining that the people do not give it so much attention as they ought, but we shall find it true in all countries and in all the centuries that it is one of the main interests of human life. There are few subjects, probably there is no other subject, to which the human race has given so much thought as to the subject of religion. The greatest buildings which have been erected on this planet were for the service of religion; more books have been written about it than about any other theme; a large part of the world's art has had a religious impulse; many, alas! of the most destructive wars of history have been prompted by it; it has laid the foundations of great nations, our own among them, and has given form and direction to every great civilization under the sun. It is not a churchman, or a theologian, it is Mr. John Fiske, one of the foremost scientific investigators, who has said of religion: "None can deny that it is the largest and most ubiquitous fact connected with the existence of mankind upon the earth."[1] About the size of the fact there is no disputing, but how shall we explain it? Where did it come from? The scientific people have puzzled their heads not a little over the question where the life on this planet came from. They cannot make up their minds to say that it came from non-living matter; and some of them have ventured a guess that the first germs might have been brought by a meteorite from some distant planet. That, however, only pushes the mystery one step further back: how did it come to be on that distant planet?
