He is a member of a Society founded chiefly for this purpose: to strive especially for the defense and propagation of the faith and for the progress of souls in Christian life and doctrine, by means of public preaching, lectures, and any other ministration whatsoever of the word of God and further by means of the Spiritual Exercises, the education of children and unlettered persons in Christianity and the spiritual consolation of Christ's faithful through hearing confessions and administering the other sacraments.
Moreover, he should show himself no less ready to reconcile the estranged, compassionately assist and serve those who are in prisons or hospitals and, indeed, to perform any other works of charity, according to what will seem expedient for the glory of God and the common good.
