The Catholic Catechism (Hardon)

The Catholic Catechism is a major volume on the teachings of the Catholic Church written by John Hardon and published in 1975. It was written at the request of Pope Paul VI to counter the emergence of perceived rampant liberalism after the Second Vatican Council (1962-1965).

First edition (publ. Doubleday)

The Catholic Catechism was a significant work in the sense that it essentially brought modern Vatican II Catholic teaching and faith into one book, unlike any other before, and was a precursor to the Catechism of the Catholic Church, which is the official codified teaching of the Catholic Church, written by Joseph Cardinal Ratzinger (now Pope Benedict XVI) and promulgated by Pope John Paul II in 1992.

Hardon's Catholic Catechism remains a standard work on Catholic orthodoxy even to this day.

The book is published with the nihil obstat and imprimatur.
