I recently received a copy of “A Small Catechism For Catholics” originally written by St. Peter Canisius and translated from the original Latin by Ryan Grant. This is published by Mediatrix Press.

This is an absolutely fascinating translation of a fascinating Catechism. This Catechism is written with precision and clarity. In a question and answer format, it allows for simple questions to be answered quickly and concisely, and encourages memorization of its passages. It is a must have for every single Catholic. At 65 pages in length, it is a very quick read of no longer than an hour. It has not been tainted with modernism, thus we know it holds true to the teachings of the Church. St. Peter Canisius is also a Doctor of the Church.

I would suggest you purchase it. You can do so through Amazon. It appears the new version of the book includes a special Foreword by Fr. Chad Ripperger.

To demonstrate how this book is aligned with the traditions and teachings of the Church, I would like to include this excerpt which discusses who are outside of the Church and  who are heretics. (pgs 13-15)

Who are altogether foreign to the Church?

In the first place, Jews and all unbelievers and also apostates from the faith; thereafter heretics, those who, of course, were baptized, but pertinaciously uphold error against the Catholic faith. Besides these, schismatics, those who separate themselves from the peace and Catholic unity itself; and last of all, those who are legitimately excluded from the communion of Saints, from the participation of the Sacraments and the aid of the Church and from divine offices, throughout Ecclesiastical power, wherefore they are called “the excommunicated”.
All those who are separated and foreign to the body of Christ, which is the Church, and hence remain outside of the spiritual life and salvation, unless they should recover their senses, are guilty and merit eternal death, that is Satan. Moreover, while all these are to be avoided by Catholics, more particularly, heretics and schismatic should be detested and avoided no less than some deadly plague.

At length, what might be a simple, short and upright rule of faith, by which Catholics are distinguished from heretics?

It is this, they confess the faith of Christ and the full authority of the Church; and it behooves them to hold that as certain and fixed, which the Shepherds and Teachers of the Catholic Church have defined must be believed. The others, who do not listen to the Church, should be to you, as Christ himself said “As a heathen and a tax-collector.” (Matthew 18:17) Indeed he who refuses to have the Church as a mother, will not have God as Father.

Yes, this is 100% accurate and Catholic. If you’re Catechism doesn’t include this, it does not cut it.
