14 In this so vast field, wherein, as representative of the pacific King, We have lavished Our especially attentive cares, We make an appeal for the zealous help of all those who claim for themselves Christian peace, but especially for the collaboration of the Tertiaries. They will exert a marvelous influence in restoring concord in spirit the day wherein their number and their efforts will be developed. It is, then, desirable that in every city, town, and even in each village, the Third Order count henceforth a sufficient group of members, not of inactive adherents satisfied with the mere title of Tertiaries, but instead, of those who spend themselves with zeal for their own salvation and the salvation of their brothers. Why even should not the various Catholic associations which multiply everywhere, associations of youth, of workmen, of women, not affiliate themselves to the Third Order to continue to work for the glory of Jesus Christ and the triumph of the Church with the same zeal that Francis had for peace and charity?
