27 You see now, Venerable Brethren, how much We have desired to explain and inculcate these principles concerning Catholic Action which is to be sustained and promoted in Italy. It is not sufficient to point out the good; it also must be put into practice. Your own exhortations and paternal interest will render an inestimable service to the cause. Although the beginnings are humble, as is the case in all beginnings, divine grace will cause it to grow and prosper in a short time. All Our children who dedicate themselves to Catholic Action should once again listen to the advice which arises so spontaneously from Our heart. Amid the bitter sorrows which daily surround Us, We will say with Saint Paul, "if . . . there is any comfort in Christ, any encouragement from charity, any fellowship in the Spirit, any feelings of mercy, fill up my joy by thinking alike, having the same charity, with one soul and one mind. Do nothing out of contentiousness or out of vainglory, but in humility let each one regard the others as his superiors, each one looking not to his own interests but to those of others. Have this mind in you which was also in Christ Jesus." Let Him be the beginning of all your undertakings: "Whatever you do in word or in work, do all in the name of the Lord Jesus Christ." Let Him be the end of your every word: "For from him and through him and unto him are all things. To him be the glory forever." On this day which is so reminiscent of that when the Apostles, full of the Holy Spirit, went out of the Cenacle to preach to the world the Kingdom of Christ, may the power of that same Spirit descend upon all of you. "May He bend whatever is rigid, inflame whatever has grown cold, and bring back whatever has gone astray."
