Every Catholic should be taught the Faith by the best books. Every Catholic should have a copy of the Catechism that will last them a lifetime. Every Catholic should have a copy of the Catechism of the Council of Trent. 
For, as Pope Leo XIII once said on this very book, 
“This work is remarkable at once for the richness and exactness of its doctrine, and for the elegance of its style; it is a precious summary of all theology, both dogmatic and moral. He who understands it well will have always at his service those aids by which a priest is enabled to preach with fruit, to acquit himself worthily of the important ministry…of the direction of souls, and will be in a position to refute the objections of unbelievers.”
