5 We should like first of all to touch here briefly on the progress that has happily been made. In 1926 the number of Catholic missions amounted to 400, but today it is almost 600. At that date the number of Catholics in the missions did not exceed 15,000,000 while today it is almost 20,800,000. At that time the number of native and foreign priests in the missions was about 14,800; today their number is more than 26,800. Then all Bishops in the missions were foreigners; during the past 25 years 88 missions have been entrusted to native clergy; moreover with the establishment of the Ecclesiastical Hierarchy and the appointment of native Bishops in quite a few places, it has become more apparent that the religion of Jesus Christ is really Catholic and that no part of the world is excluded from it.
