I am just old enough to remember Fr. Charlie Curran leading the CUA theology faculty out on strike in an open defiant protest against Humanae Vitae. IIRC, Cardinal Patrick O'Boyle tried to bring ecclesiastical sanctions against Curran, only to be told to back off by the Vatican!
So they could continue to disobey and obstruct real Catholic docrine, and form their own alternative "Magesterium of the University," and no heads rolled. They continued to stay in the structure of the Church and foment their vile rebellion. They lost on doctrine yet they won the day.
What was it that Tom Bethell wrote about it? Whoever can fill us in on the details (Arthur?) please do so.
Geo weighed wrote about it
The Vatican issued humanae vitae. The account of the Vatican siding with dissidents is not quite correct
And the Vatican certainly did not dissent with the very teaching it produced and which it still publishes and teaches. JPII a theology of the body draws on humanae vitae and it is widely accepted in groups obedient with the vatican
