When in the sixteenth century the great revolt against the authority of the pope and the religion of the Roman Catholic Church gave birth to the Protestant churches, they, too, in the main, formed alliances with the states in which they were founded. Nay, in the very struggle for their existence, the states of Germany, of Holland, Scandinavia and of England, drew the sword in their behalf and by their support made it possible for the seceding religionists to establish churches despite all efforts of the Roman pontiffs to prevent them; and after the revolution was an accomplished fact, the states above enumerated continued to give support to the churches founded within their borders. If the church and the state in some instances were regarded as separate and distinct societies, they acted at the same time as close neighbors, and nearly interested in each other's welfare. If they lived separate, they were not estranged; and each at need gave the other support. I have thought it necessary to call the attention of the reader to the conditions in which Christianity has existed since the days of Constantine under all three great divisions of Christendom--the Roman Catholic, the Greek Catholic, and Protestant--in order that he might be reminded of the fact that circumstances of the most propitious character have existed for the propagation of the so-called Christian religion. Christendom has had at its command the wealth and intelligence of Europe; it has been able to follow the commerce of European states into every country of the world; and not only its commerce, but its conquests as well; and wherever the love of adventure or the desire for conquest has led Christian soldiers, Christian priests have either accompanied or followed them, that the gospel, in the hands of the Christian minister, might be a balm for the wounds inflicted by the sword in the hands of the Christian soldier; so that if Christian armies were a bane to the savages, the Christian priests might be an antidote! Yet with all the advantages which came to Christianity through the support of the state; with the intelligence and wealth of Europe behind it; with the privilege of following in the wake of its commerce and conquests; what has Christendom done in the way of converting the world to its religion? But a little over one-fourth of the inhabitants of the earth are even nominally Christian! There are in the world, according to statistics published on the subject: Roman Catholics ...........................206,588,206 Protestants (all sects) ................... 89,825,348 Greek and Russian Churches ................ 75,691,382 Oriental Churches ......................... 6,770,000 Making the total of all Christians........ 378,874,936. The other religions stand as follows: Brahminical Hindoos .......................120,000,000 Followers of Buddha, Shinto and Confucius .................................482,600,000
