Its all a volunteer work, all free online, and a work in progress. I originally was only going to design it with footnotes from commentary from the Church Fathers and other traditional minded Catholic commentators, and that is my main goal, to provide commentary for every book of the Bible. But I have also added complete commentaries to the site in order for be a reference tool in the meantime.
Right now I am providing footnotes from great commentators that have not been translated into English yet, such as St. Albert the Great, Hugh of St. Cher, Anselm of Leon, Martin of Leon, Glossa Ordinaria, Nicholas of Lyra, etc etc. I am designing it to resemble the Haydock Bible, that is, comments from other commentators put together to form one commentary that is gleaned from the best of the best commentators, mostly Medieval commentators.
With it being all volunteer and all mine, I can bypass a lot of red tape and make a resource that I have always dreamed of making for people who study the Bible! I wish only I had a team with a like-minded vision to speed up the process!
