No, he didn't. This story is false.
Correct. This guy has been on here with no other purpose than to slander +Thuc bishops and SVs in general.
So the origin of this false rumor is that at one point Archbishop Thuc did, under pressure, participate in some concelebration (on orders from the bishop where he was at), but he said that he was in the ceremony but withheld his intention to participate and to "consecrate" during that concelebrated Mass.
At no time did he state that he withheld intention to consecrate anyone. Now, there were some who falsely claimed that they were consecrated by +Thuc that +Thuc denied having consecrated, but he always affirmed and re-affirmed having consecrated the major episcopal lines active in the US currently.
There are some shady lines out there that need to be avoided where there's no proof that the originator of the line was actually consecrated, but the line through DesLauriers and Carmona are certainly valid.
