His Reign Shall Have No End: Catholic Social Teaching for the Lionhearted
His Reign Shall Have No End is a new introduction to traditional Catholic Social Teaching (CST). Too often, this subject is reduced to a grab-bag of catechetical truisms and welfare policies driven by modern secular, egalitarian, and pluralist assumptions. Instead, Dr. Kwasniewski traces all of its major elements back to the world-changing mystery of the Incarnation, whereby the Son of God became Head and Ruler of mankind in regard to goods both natural and supernatural. So far from being superseded by the "march of events" or what some would call "progress," the kingship of Jesus Christ-a revealed truth given consummate formulation by Pope Pius XI in his 1925 encyclical Quas Primas-is nothing less than the master key to CST's coherence and, more importantly, to the flourishing of nations no less than the beatitude of individuals. Wherever this kingship is ignored or denied, individuals, families, whole societies decompose like a body deprived of a soul; wherever it is welcomed in faith, Christian life revives and Christendom stirs from slumber. Divine Providence raised up Pope Leo XIII to guide the reconquest; his teaching is taken here as the unsurpassed guide to the thorniest political and economic questions that confront the human race at a time of tremendous upheaval.

Fantastic Book
I read this book from cover to cover, and it was very interesting and valuable to me as a Catholic convert, but also to my husband who is a cradle Catholic, and also a big Peter Kwasniewski fan. It was a fascinating read and it challenged many of my assumptions and beliefs, especially around libertarianism and capitalism.
And as always with Peter Kwasniewski, be it throughout his writing or in interviews, he sneaks in a ton of recommendations for excellent books which I have already lined up for future reading. I highly recommend this book to all Catholics who want to understand the true social teaching of the Church, and not the distorted toothless versions promoted since the 1960s.

Dr. K’s brief presentation of CST was truly accessible, broadening and clarifying my understanding of the subject. His chapters exploring teachings on economics were particularly helpful to me and opened my eyes to the real injustices among different models while also describing distributism in a way I finally understand. I underlined multiple passages for future reference. Definitely recommend having a copy on every Catholic bookshelf.
