This program offers Sacred Scripture, its interpretation in light of Sacred Tradition and the teachings of the Magisterium, with appropriate theological commentary and exegesis.Clearly I am going to be spending some time there. You can even download the entire content. I linked to the English version, but there are five other languages available as well.
The downloadable version allows you to connect Sacred Scripture to the complete works of many Doctors of the Church, Councils, Encyclicals, teachings of the Popes, Catechisms, as well as commentaries from secular literature, etc.
