I would like to know about this myself. Why did ABL sign those docuмents in the first place? Does he ever explain why and when he came to the realization that he made a huge mistake? How long did it take him?
Many concerns were raised for many of the docuмents by many bishops. Those concerns were answered, by and large, adequately by Vatican officials. What the bishops didn't know was that the very officials who were answering their questions were also the ones who intended to use the docuмents' vagueness to remake the Church. (This is also, by the way, another item of evidence that there was no valid pope as this could not have happened, in my opinion, if the Holy Ghost had been protecting Peter from the evil one.)
In any event, although the archbishop's signature is reported to have been attached on all 16 docuмents, the archbishop denied having signed at least two of them. I have read that the bishops present had to sign attendance rosters each day they were present for a general session and that Archbishop Lefebvre did indeed sign a docuмent he believed was simply an attendance roster that was later attached (rightly or wrongly) to two of those docuмents.
I heard part of this explanation in at least one cassette tape recording of the archbishop giving a conference (the cassette, I'm afraid, no longer exists, but I did hear it). He maintained in the conference that he did not sign all of the docuмents though the only one he specifically named in the conference was the docuмent on religious liberty since that was what he was talking about at the time.
