You’re thinking of Marcel Lefebvre. Although he got into trouble for rejecting liturgical reforms, what actually got him excommunicated was ordaining four of his own bishops without Vatican approval.
He died in 1991, 14 years before Ratzinger became pope. His excommunication remained in force. Ratzinger did, however, lift the excommunication on the four bishops who were ordained by him.
Jeannine Gramick and Robert Nugent. The weren’t excommunicated; they were directed not to engage in pastoral work with lesbian and gay people.
Nugent accepted the order and returned to parish ministry; Gramick has rejected it and continues in her ministry to gays and lesbians, and is supported in that by the Catholic religious order of which she is a member. She has not, so far as I know, been further disciplined by the Vatican.
On the way to schism it is, dammed if you do, dammed if you don’t for the Church to enforce the rules; as with the contraceptive example it is clear to me that a growing division is taking place.
And I would not be against it, as the new church will be more responsive than the old Roman farts one. But when I look at history I expect that countries, in the Americas specially, will then have yet another reason to rekindle old divisions.
There are several lists of papabile already out there, but who knows? As the old saying goes, “He who enters the conclave a Pope leaves it a cardinal.”
There are a few. There’s Lehman. There’s Danneels. There’s Hummes. There’s Bergaglio. (There’s Mahony, but given the situation…) But there are some more than just those. They’re a minority right now, but they exist.
