Metropolitan Judson (1994) received a pallium at the Sistine Chapel from the Holy Father, but I don’t remember when that was. For Metropolitan Basil (2002) I never heard of him receiving a pallium, nor have I heard of what happened with Metropolitans Thomas (1991) or Stephen (1969).
My brother, as you are no doubt aware, the “canonical requirement” for the hierarch of a
sui juris Metropolitan Church to “request a pallium” was written into the CCEO.
I am not sure whether or not either of the first two Metropolitans of the Byzantine Catholic Church of Pittsburgh
sui juris (Stephen and Thomas) received a pallium, especially Metropolitan Stephen, as his appointment well predated the CCEO.
There is a famous story surrounding the event in the Sistine Chapel whereby Metropolitan Judson received his pallium. Apparently, the Ecumenical Patriarch (who was invited for the occasion of the Feast of Sts. Peter & Paul, when the pallium was to be bestowed) expressed great dissatisfaction when he heard that an Eastern Catholic hierarch was required to request and would be given a Roman style vestment, inconsistent with his own traditions, as a symbol of office. So, instead of receiving the pallium with his brother Latin Catholic bishops at the scheduled ceremony, it was given to him separately in a ceremony held afterward in the Sistine Chapel.
Metropolitan Basil was canonically bound to “request a pallium” in connection with his appointment (confirming his acceptance, in effect), but I understand he did not go to Rome to receive one formally in consideration of the objections raised in Metropolitan Judson’s case.
Pope Benedict XVI, with great fortitude, decided that an omophorion should be more properly given to Metropolitan William on this occasion, and he should not be excluded from the general ceremony. Rather, the Roman practice of imposing a pallium was adapted in his case, and the corresponding vestment appropriate to his Rite and tradition was given instead, to seal his appontment as head of an Eastern Catholic Metropolitan Church
sui juris.
FWIW & IMHO, this was a good response and a very good result. Some would argue from a more Orthodox point of view that this should not be at all necessary, and with merit. However, given that we are members of the Catholic Communion, and the Eastern Catholic Churches are still not well understood, this change is both suitable and provided an opportunity for catechesis as well as proper recognition of the Eastern Catholic Churches and hierarchs.
That said, I still struggle to understand the custom on the Western side of the aisle. We are taught that all bishops share responsibility for the preservation of the Church equally, yet Metropolitan Archbishops in the Latin Church are singled out for receipt of the pallium as an honor and symbol of “higher office”. At least in the case of a hierarch of a Metropolitan Church
sui juris, there seems to me to be a more logical basis for the additional “pomp” and formality. To me, this might be more problematic in the eyes of the Orthodox, as it seems to reinforce a notion of a separate class of bishops.
