Was Bishop Williamson one of the other bishops?
PS: What is the source of that quote? I can't find it, unless you are referring to this statement from his Letter to Bishop Fellay: "After these events, in noting your good will and based on the fact that your Fraternity certainly was not spreading any heretical doctrine and did not maintain schismatic attitudes, I had dared you to propose, without consulting anyone first, to set a possible date for reintegration."
Oh, here it is, from the same Letter:
You yourself, dear Mgr. Fellay, after having heard from several members of the Fraternity and having met your Council, sent to me the secretary of the Society of St. Pius X, Don Selegny, accompanied by Don Simoulin, with the mission of presenting several questions concerning the formulas of an eventual reintegration. The secretary, after having heard my responses articulated to his numerous questions, expressed himself in an extremely harsh manner about the present rite of the Holy Mass, as the faithful united to the Vicar of Christ and their Bishops adhere to, in claiming that this rite was evil; he informed me moreover of having received from you a mandate to suspend the dialogues, if two prior conditions were not granted: to lift the excommunication and to permit all Catholic priests to celebrate according to the rite of St. Pius V.I should say that I was left saddened and perplexed, because this development was not in line with the climate of trust, of cordial fraternity and reciprocal respect which, until then, had sustained and animated our relations.
Since the beginning, starting out from a sound, fundamental position, a hope was kept alive of being able to put an end to the irregular situation in which your Fraternity finds itself; even more so because I noted neither the scent of heresy nor the will to incur a formal schism on your part, but only the desire to contribute to the good of the universal Church, considering that the specific charism of the Society of St. Pius X toward Tradition, in the current context, could only benefit the path of the Church.
It was absolutely not a matter of a trap, set up to silence you or destroy your movement, and a base strategy with hidden intentions or with unconfessed aims was never followed, as certain among you have written to the contrary.
I can say that on the part of the Holy See and of all people involved in this difficult but promising episode for the unity of the Church, we never lacked the honest desire to see the Society of St. Pius X reconciled with the See of Peter so that, with its particular charism of service to Tradition, it could contribute to the missionary work of the new evangelization.
Also, although I did not doubt the disposition of Your Excellency to continue our dialogue toward the desired end, I am surprised at the declarations you and other members of the Society of St. Pius X have made on this subject.
It seems to me in fact that your declarations, which appear to cast doubt on the sincerity of the Holy See, are not useful in making our common efforts thrive, and have created a less favorable climate and cast doubt on the Society of St. Pius X’s understanding of this important matter.
Permit me, therefore, to quote some of your statements, enumerating several of these contradictory attitudes and assertions in which your Fraternity seems to be risking itself, which create perplexity and are in contradiction to the Tradition of the Church. Besides, how could I not confront these painful points, if they contained questions that invite at least some explanation?
"Was Bishop Williamson one of the other bishops?"
I do not believe that Bishop Williamson was in attendance. All the rest were, as far as I recall.
The entire quote you gave is the one I attempted to paraphrase.
