The subtitle of the sixth and final volume of The Vincentians, Internationalization and Aggiornamento (19191980), describes the growth and change of the Congregation of the Mission in the twentieth century. Formerly European in focus, the provinces of the Congregation gained their own voice. Membership in mission lands, such as China, Brazil, and Ethiopia, surged, as local vocations joined their European confreres. The same is true of maturing provinces elsewhere. St. Vincent de Paul's congregation became internationalized in both outreach and membership.
The Vincentians in these recent decades also tasted the bitterness of persecution. The Congregation was suppressed at various times in Europe, Latin America, Asia, and Africa. Its members often reacted by moving elsewhere, thus furthering the internationalization of the Vincentian charism.
