There are probably many who have tried to find a particular sentence/s in the Catechism;
you know you read it, but where
1. **CCC Word Search **
There is a great online tool where you can search for particular words in the CCC. If you can remember for certain one of the words, then you can find the sentence. The more unusual the word, the quicker you’ll find it. Here is the link:
Directions for use are given. After clicking on the letter, you can use the “control F” method, or you can just scroll down the list that comes up until you come to your word. The CCC paragraph # appears to the left of the word. When you click on it, it brings up the Catechism section in which the word appears. The word will be lightly highlighted and most often is in the first sentence at the top of the screen.
Another site: scborromeo.org/ccc.htm
Just type the word in the search box.
I usually use the Vatican site first because more findings are visible at a time on the computer screen. However, for some reason, the Vatican site doesn’t give links for a few words. Those words will appear in bold print. Nothing will happen when you click on it. In those cases I go to the borromeo site.
2. Index of Citations - Sacred Scripture CCC search
If you can’t find it with the word search but know a Scripture passage that you think might be referenced in a footnote, you can do a search on the Catechism’s “Index of Citations - Sacred Scripture” at this site. Be sure to use the same abbreviations for the books of the Bible that the Catechism uses.
3. Index of Citations - Ecclesiastical Writers CCC searchThis would be where you could locate any references to where there were footnote references to works of various writers - eg. Augustine, Aquinas, …
If you have the Libreria Editrice Vaticana Second Edition of the Catechism of the Catholic Church (dark green binding) the Index of Citations is in the back of the book right after the last page of the Catechism text.
I’ve been unable to find an online Ecclesiastical Writers search. Does anyone know of one?
