Have you personally read any of his works, or are you solely relying upon hearsay from this forum and other internet sources (which are cited as “authoritative” sources to the point of death)?
Without having actually read the works which you attempt to undermine, you have no basis of criticism. Fr. Brown has contributed much more to the field of biblical scholarship than your accusations attempt to detract.
Fr. Brown stated himself that he believes in all Church doctrine, including the Virgin birth, and that he follows the Magisterium. If you do not believe me, then read his 101 Questions and Answers On The Bible for yourself where he lays his opinions out on the table for all to see.
As for your accusation that he denies the Virgin birth, he answers you quite clearly in the book:
“Forgive me for rather bluntly insisting that you pay attention to what I said. I did not say that the birth stories are not historical. I gave reasons why scholars think that some of the events described in those stories are not historical…I always emphasize that, besides disagreeing on certain matters, the two evangelists also agree on what might be called the most important points…[which] are very important agreements, and I would argue that a case can be made for the historicity of such details.” (101 Questions, pg. 80)
Any reading of his *Birth of the Messiah *will reveal this. Any actual open-minded reading of his books will demonstrate to the reader that he does not attempt to speak *as *or *for *the Magisterium.
Maybe it’s you who need to examine who you do and do not label as ‘orthodox’ without proper examination?
