The United States Conference of Catholic Bishops has posted (in PDF) the general results of the Vatican’s Apostolic Visitation of U.S. seminaries. Diocesan seminaries fare very well. Here’s a sad line, though: “nearly all Visitation reports noted lacunae in the programs. Mariology and Patristics were frequently mentioned as being among these laucnae.” [Emphasis added.] If you don’t have the patience for long reports in light print, there’s a good summary here.
In my diocese, the sems have a good man teaching patristics, my sometime co-author Father Kris Stubna.
