26 As men are generally stimulated, Venerable Brethren, openly to profess their Catholic faith, and to harmonize their lives with its teaching, by brotherly exhortation and by the good example of their fellow men, we greatly rejoice as more and more Catholic associations are formed. Not only do We hope that they will increase, but it is Our wish that under Our patronage and encouragement they may ever flourish; and they certainly will flourish, if steadfastly and faithfully they abide by the directions which this Apostolic See has given or will give. Let all the members of societies which further the interests of God and His Church ever remember the words of Divine Wisdom: "An obedient man shall speak of victory" ( Prov . xxi. 8), for unless they obey God by showing deference to the Head of the Church, vainly will they look for divine assistance, vainly, too, will they labour.
