You reference a story with which I am not familiar. However, wouldn't a person named "Sandro" be a man? And I have to confess that I'm underwhelmed with leakers and sneakers these days ... fallout from the re-emergence of "Deep Throat," perhaps.
I seem to be in the minority on the gender of Sandro.
I'll take your word that S. is a male.
The story, as briefly as possible: Back during the campaign, the Bishops were under some pressure to speak with a unified voice and make Kerry unwelcome for Communion. Abp. Burke (and others) were quite clear and vocal on the topic, and what they wrote was impeccable in terms of Canon Law.
Other Bishops (you know their names) would not THINK of tossing a fellow-liberal into the pit of practical excommunication.
At a Bishops' meeting in Denver, McCarrick pulled out a letter from Ratzinger and told his brother Bishops that R, in effect, stated that McC's position (don't anathematize Kerry) was just fine.
Except McC lied. The ACTUAL letter from R. was leaked and it was quite different from the one McC quoted. R. backed Burke...
Magister "found" the actual letter...
