The Great Encyclicals of Pope Leo XIII offers a rare and compelling look into one of the most influential pontificates in Church history. Spanning a full 25 years, Pope Leo XIII’s reign addressed the spiritual and societal upheavals of the modern world with clarity, courage, and Catholic conviction.

This two-volume set, compiled and introduced by Leo L. Clarke, collects thirty-one of Pope Leo’s most significant encyclicals. Volume One: The Social Letters explores how the Catholic faith engages with civil society. It includes foundational texts like Rerum Novarum on labor and capital, Longinqua on Catholicism in America, and Leo’s very first encyclical, Inscrutabili Dei Consilio.

Volume Two: The Spiritual Letters turns inward, offering reflections on core teachings and devotions of the Church. It features important writings like Aeterni Patris (on Thomistic philosophy), Providentissimus Deus (on Sacred Scripture), and several letters on the Holy Rosary.

Each encyclical speaks with enduring relevance, affirming the role of the Church in modern society and guiding Catholics toward truth, justice, and holiness. Whether for study, spiritual formation, or theological reference, this set is an essential addition to any serious Catholic library.
