A big kiss on the hand for the Vatican Congregation for Clergy and their online Biblia Clerus. The entire Bible is presented with commentary from the Doctors of the Church, Councils, Encyclicals, teachings of the Popes, Catechisms, as well as commentaries from secular literature. You can read it online or download it to your computer. The Biblical text appears in the New American Bible and Revised Standard versions, and you can read it in Latin too.
This resource is definately worth exploring.
