Since I posted the original message (see below) I had lunch with a priest friend. I mentioned the letter to him and lo and behold he told me that a priest friend who was at the same meeting had called and told him about it also. He said that originally the priest was going to fax him a copy of the letter, but then got cold feet and read part of it over the phone to him. The part he read, and the part that my source (a Bishop) mentioned to me was that the seminary was to enforce a missive that originally had been sent out in 1960. None of the parties that have heard this know what missive from 1960 is being referred to, but it could be this document that Rod Dreher refers to in his Monday column:.
Rome has explicitly discouraged the ordination of homosexuals since at least 1961. For the past decade, the Vatican has been ratcheting up the pressure against gay ordination — to little avail in most U.S. dioceses.
My priest friend seemed to think that the letter was sent just to the seminary that both sources say received it, but my source told me that he thought that it had been sent to every seminary in the US.
Again, the reason the letter (which supposedly was secret--but you see how well secrets are kept in clerical circles) was shared at the meeting was because the Rector evidently had no idea of how it was supposed to be practically enforced.
