The Aquinas Catechism

Vatican calls this book a Masterpiece!

LAUDED BY OVER 25 POPES, the author gives you in this compact book an intro to the Faith, a refresher catechism by the Church's greatest mind, a mini-course in Scripture by an unexcelled master of the Bible (with 1,000 Scripture quotes), a brief course in theology taught by the Church's greatest theologian, and a defence of the Faith against its critics. Is it a Catholic masterpiece? You bet!



"His teachings
could have come only
from a miraculous
intervention by God."

Pope John XXII

St Thomas and Dove





Vision of St Thomas Aquinas


"As it was said of old to the Egyptians in time of famine:
Go to Joseph, that they might receive from him a supply of wheat to nourish their bodies,
so We now say to all who are seeking the truth: Go to Thomas.

"Go and ask Thomas for the food of sound doctrine, which nourishes souls for eternal life, and which he possesses in rich abundance."

Pope Pius XI



St. Thomas Dedicating His Works to Christ
by Santi de Tito (1593)



"The teachings of St. Thomas are so vast that they contain, like a sea, all the wisdom that flows from the ancients: all the truths that had been spoken, all that had been wisely sifted by the pagan philosophers, by the Fathers and the Doctors of the Church, by the eminent men who flourished before him."

Pope Leo XIII

Aquinas Teaching


Sts. Gregory, Jerome, Augustine, and
Dominic listen while St. Thomas teaches.




"Because his method is concise,
clear and easily followed, even persons
of little instruction are eager
to possess his writings."

Pope Pius XI





The most extraordinary
(and little known) book
ever written about our Faith

. . . was not written for philosophers or for theologians --- even though its author was the incomparable St. Thomas Aquinas, the man lauded by more than 25 popes as the Church's preeminent theologian.

Its pages contain the Lenten sermons St. Thomas preached to the townspeople of Naples in 1273, soon before his death. Citing almost 1,000 quotations from the Bible, St. Thomas preached eloquently on:

The Our Father

The Hail Mary

The Sacraments

The Commandments


The Apostles' Creed

Gathered together now in one book, these sermons constitute a complete catechism on the teachings and practices of our Faith, and reveal the profound links that bind Holy Scripture to each of them.


Aquinas Catechism


In one volume,
The Aquinas Catechism
gives you:

An introduction
to the Catholic faith

A refresher catechism
by the Church's greatest mind

A mini-course in Scripture
by an unexcelled master
of the Bible, with almost a
thousand Scriptural quotations

A brief course in theology
"taught" by the Church's
greatest theologian; and

A defense of the faith
against its critics


Best of all, because St. Thomas was not writing for scholars but preaching to laymen, anyone can profit from the saintly wisdom found here.

To ensure that happens, we have (as the Vatican joyfully notes below) designed our edition of these sermons for ease of use: boldfaced subheadings on every page make them easy to read and our handy 22 page appendix outlines the entire book for you.


"A Masterpiece!"
Vatican newspaper

"To give highlights of this masterpiece is difficult because so much is distilled. The benefits of prayer are presented so attractively that one wishes one could pray for hours on end. A very clever editor put in helpful headings and subheadings to bring out more clearly the meaning of the text. Now beginners and advanced scholars alike can understand the faith more aptly through these brilliant sermons of the Angelic Doctor."
