“The Church first used the term “social justice” in the 1850s after witnessing the material inequality plaguing humanity that came in the wake of the progress of the industrial revolution. Blessed Paul VI expanded on this concept of social justice in his 1971 apostolic exhortation, Evangelica Testificatio, writing about the role religious institutes (groups like the Dominicans and Franciscans) play in advocating for social justice: “It is certainly true that religious institutes have an important role to fulfill in the sphere of works of mercy, assistance and social justice; it is clear that in carrying out this service they must be always attentive to the demands of the Gospel.” For Blessed Paul VI, it was not just the role of a religious to carry out acts of civil service, but to carry out those acts with charity and a genuine love of Christ.
When building up the Kingdom of God through social justice, Christians look not just at the Church but at the whole world, taking into account the needs of all human beings. This may translate into helping with alleviating a practical need such as food or clothing while witnessing to the belief that all humans made in God’s divine image are deserving of complete charity. In carrying out acts of social justice while following the model of Catholic social teaching, Blessed Paul VI calls religious institutes to take on the work of the Church. This work can take the form of dispensing boxes of canned foods or distributing warm winter coats to those who need them. These small acts of addressing the material needs of others help contribute to the ultimate goal of making Christ’s love known to all men.
But what makes “the work of the Church” any different from similar secular social services? Social workers and secular shelters and charities are able to give material benefits to the poor, but Blessed Paul VI recognized that Catholics needed to aim toward something higher: the spiritual needs of the soul. To carry out works of social charity for the love of God means to share the Gospel with those one serves and to pass along the message of hope and salvation to all who receive these works of charity. To be “attentive to the demands of the Gospel” means to care for the salvation of the human person and to allow the work of social justice to be a means of putting Christ’s love into action. To do the work of the Church is not only to feed the hungry and clothe the naked, but to be able to speak eloquently about God’s love for His creation and to be aware of the many material and spiritual needs of His Church.”
Summa Catechetica, "Neque enim quaero intelligere ut credam, sed credo ut intelligam." – St Anselm, "Let your religion be less of a theory, and more of a love affair." -G.K. Chesterton, "I want a laity, not arrogant, not rash in speech, not disputatious, but men and women who know their religion, who enter into it, who know just where they stand, who know what they hold and what they do not, and who know their creed so well that they can give an account of it."- Bl John Henry Newman, Cong. Orat., "Encounter, not confrontation; attraction, not promotion; dialogue, not debate." -cf Pope Francis, “You will not see anyone who is really striving after his advancement who is not given to spiritual reading. And as to him who neglects it, the fact will soon be observed by his progress.” -St Athanasius, "To convert someone, go and take them by the hand and guide them." -St Thomas Aquinas, OP. 1 saint ruins ALL the cynicism in Hell & on Earth. “When we pray we talk to God; when we read God talks to us…All spiritual growth comes from reading and reflection.” -St Isidore of Seville, “Also in some meditations today I earnestly asked our Lord to watch over my compositions that they might do me no harm through the enmity or imprudence of any man or my own; that He would have them as His own and employ or not employ them as He should see fit. And this I believe is heard.” -GM Hopkins, SJ, "Only God knows the good that can come about by reading one good Catholic book." — St. John Bosco, "Why don't you try explaining it to them?" – cf St Peter Canisius, SJ, Doctor of the Church, Doctor of the Catechism, "Already I was coming to appreciate that often apologetics consists of offering theological eye glasses of varying prescriptions to an inquirer. Only one prescription will give him clear sight; all the others will give him at best indistinct sight. What you want him to see—some particular truth of the Faith—will remain fuzzy to him until you come across theological eye glasses that precisely compensate for his particular defect of vision." -Karl Keating, "The more perfectly we know God, the more perfectly we love Him." -St Thomas Aquinas, OP, ST, I-II,67,6 ad 3, “But always when I was without a book, my soul would at once become disturbed, and my thoughts wandered." —St. Teresa of Avila, "Let those who think I have said too little and those who think I have said too much, forgive me; and let those who think I have said just enough thank God with me." –St. Augustine, "Without good books and spiritual reading, it will be morally impossible to save our souls." —St. Alphonsus Liguori "Never read books you aren't sure about. . . even supposing that these bad books are very well written from a literary point of view. Let me ask you this: Would you drink something you knew was poisoned just because it was offered to you in a golden cup?" -St. John Bosco
