Henry M. Taber, the author, has for many years taken great interest in religious questions. He was raised in an orthodox atmosphere, was acquainted with many eminent clergymen from whom he endeavored to find out what Christianity is--and the facts and evidence relied on to establish the truth of the creeds. He found that the clergy of even the same denomination did not agree--that some of them preached one way and talked another, and that many of them seemed to regard the creed as something to be accepted whether it was believed or not. He found that each one gave his own construction to the dogmas that seemed heartless or unreasonable. While some insisted that the Bible was absolutely true and the creed without error, others admitted that there were mistakes in the sacred volume and that the creed ought to be revised. Finding these differences among the ministers, the shepherds, and also finding that no one pretended to have any evidence except faith, or any facts but assertions, he concluded to investigate the claims of Christianity for himself. For half a century he has watched the ebb and flow of public opinion, the growth of science, the crumbling of creeds--the decay of the theological spirit, the waning influence of the orthodox pulpit, the loss of confidence in special providence and the efficacy of prayer. He has lived to see the church on the defensive--to hear faith asking for facts--and to see the shot and shell of science batter into shapelessness the fortresses of superstition. He has lived to see Infidels, blasphemers and Agnostics the leaders of the intellectual world. In his time the supernaturalists have lost the sceptre and have taken their places in the abject rear. Fifty years ago the orthodox Christians believed their creeds. To them the Bible was an actual revelation from God. Every word was true. Moses and Joshua were regarded as philosophers and scientists. All the miracles and impossibilities recorded in the Bible were accepted as facts. Credulity was the greatest of virtues. Everything, except the reasonable, was believed, and it was considered wickedly presumptuous to doubt anything except facts. The reasonable things in the Bible could safely be doubted, but to deny the miracles was like the sin against the Holy Ghost. In those days the preachers were at the helm. They spoke with authority. They knew the origin and destiny of the soul. They were on familiar terms with the Trinity--the three-headed God. They knew the narrow path that led to heaven and the great highway along which the multitude were traveling to the Prison of Pain.
