Human are vitae is accepted church teaching, heretics and dissidents notwithstanding. And the predictions and warnings have come true, as it is simple logic
No practicing catholic is confused by humanae vitae, only by the widespread rejection of it along with acceptance of induced abortion
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.
