I find it quite alarming these days to find that few Catholics have read anything about their faith written before 1960. It seems that the New Catechism and a few documents from Vatican II is all that makes up their Catholic repertoire. This is sadly the same for most of our Catechists, Directors of Religious Education as well as those running the formation programs for the diaconate, etc. Why doesn't anyone seem to realize that there is 2000 years of other material to read in addition to these few sources? It is almost as if 1960 is the cutoff point. A document written in 1907 like "Lamentabili Sane," was forgotten about over the course of 50 years and was never heard from again after the 60's. Below is a small recommended reading list to pass along to your fellow Catholics who you may run across here and there that may given them a more well rounded understanding of their faith.
Catechism of the Council of Trent
The Syllabus of Errors
The Syllabus of Pius X "Lamentabili sane"
Quanta Cura- Pius IX
Ineffabilis Deus- Pus IX
Aquinas- The Summa Theologica
The Writings of Cardinal Manning
