Click on the announcement in the OP and see it mentions Nova Friburgo, Brazil, and it's in Portuguese.
I thought that was a startup seminary too.
Perhaps the Portuguese version adds the "F" in front, too, like the French version does?
(Portugal and France are neighbors, you know.)
But that's where Bishop Tomas de Aquino lives. Why would his name be absent from all this?
I don't get it.
Just my guess, but Bishop Thomas Aquinas (who ordained Rev. Ribeiro to the diaconate a few weeks ago in Brazil) is not mentioned because:
1) He is not the ordaining bishop;
2) Rev. Ribeiro is -apparently- not a Benedictine, but an SAJM'er.
I say apparently, because I am still a bit confused about why the OP mentioned that Rev. Ribeiro was known in Brazil as "Brother" (which would imply he was a Benedictine, in which case, he would not be canonically eligible to enter/join the SAJM).
Total speculation, but perhaps he completed his temporary vows, and decided the secular priesthood was more his vocation??
As for where he did his seminary formation, I have no information, but once again, the "Brother" reference makes me think he did most (or all?) of his formation in Brazil, as I do not see his pic on any of the SAJM posts from their seminary website from last year.
I suspect Centroamerica can clear this all up, but not sure how often he is online these days, so...
