Modernists and the "New Theologians" (Authors I Would Avoid)
Watch out for these guys (or gals) when reading or buying Catholic books these days. Although some of what some of these theologians or authors had to say may have been OK, they have or have had a predisposition to modernism or even outright heresy, and their overall influence in my opinion, as well as many others, has been a negative one on the Church. Unless you are a serious theologian (Like the Pope) who has the time and knowledge to sift through some of these author's or theologian's work, and dig out what may be worth noting, I would avoid reading them. It will cost you more time than it is worth, and for those who are not well educated in the Catholic faith, they may be dangerous to read. When buying books look to see if the book is endorsed by these authors, or if they are used and quoted as primary sources. This list is certainly not exhaustive and will continue to grow. I began linking websites that have info on these authors and theologians so you can check them out for yourself. I will keep the post at the top for awhile. If you have any to add, leave the name and a source if possible in the comments section, and I will research it and add it if it is warranted. Updated 4-20-10 with more links and more authors!
