I am continually puzzled that the only men ordained in the Catholic Church seem to be from the Episcopal or Anglican (and maybe a Lutheran or two?) lines who convert to the True Faith. Why not other Protestants, such as Marcus Grodi or Scott Hahn (to name only two - there are many others, of course)? There must be a good reason somewhere.
Only men or only married men? One of my favorite priests is a convert from the Presbyterian Church. Check out the archives for the Journey Home on EWTN's web site. There are priest converts from other denominations.
