To clarify I haven’t read every religious text, but I have now read the Old/New Testament, The Baghavad Gita, The Tao te Ching, The Quaran and currently working my way through the Buddhist Sutras (looking to start on Sikhism next). That is the main text of all major religions and I only read 20-30 pages a day (with some overlap/not reading one at a time.). It’s very possible if you stick to it
