THE SUBTITLE OF THIS VOLUME is “An Era of Expansion, (1878–1919).” It reflects the reality of the Congregation of the Mission under the leadership of Antoine Fiat, the superior general who governed the Community longer than St. Vincent de Paul. Like the founder, Fiat was a man of both prayer and action. Also like the founder, Fiat was often hesitant and delayed final decisions. His confreres spread to new missions, such as the republics of Central America and Argentina, and several missions or provinces had grown large enough to be given more autonomy, such as the two American provinces, the Antilles, Barcelona, Ecuador, Belgium and Holland, Madagascar, and Colombia. China continued to attract many missionaries as well as local Chinese vocations despite war and unrest. This volume, then, relates not only that the Vincentians, members of the Congregation of the Mission, grew in number and influence, but how they exercised their ministry. Persecution was their lot in some regions, but they forged ahead. As always, they sought to align their ministries at the end of the nineteenth and the beginning of the twentieth centuries with the original mission entrusted to them by the Church through Vincent de Paul: to bring the Gospel to the poor.
