Says page 268 of Volume 2 of M’Clintock and Strong’s Cyclopædia (1891 Edition): “Christendom, the kingdom of Christ in its diffusion among men on the earth. . . . The conversion of Constantine established the first Christian state. . . . Thus the territory of Christianity at present comprises three out of the five large divisions of the world, with a considerable part of the two others. . . . Thus the time seems near when the extent of Christendom will coincide with the extent of the earth. The following estimate of the Christian population of the world is based upon the latest (1889) works on political and ecclesiastical statistics: Total Population: 1,447,548,000; Roman Catholics: 201,000,000; Protestant: 106,000,000; Christian: 393,225,000.” But today, in 1964, the world population is 3,060,800,000 [The World Almanac, 1963, pages 259, 719], and the so-called Christian population is 904,332,500.
