Daniel and the Great Unveiling
Toward the end of the liturgical year, we Catholics hear at Mass from the mysterious, often confounding, and utterly fascinating book of Daniel. Recent scholarship has demonstrated that the book of Daniel had an extraordinarily powerful influence on the first Christians, providing them a most important template for understanding the significance of Jesus.
Daniel is, of course, an example of apocalyptic literature, which in the common understanding means that it has to do with the end of the world.
Bishop Robert Barron expands on this in his article on Word on Fire.
