It was the new Springtime of VII that allows all sorts of heresies and
strange and unnatural beliefs. And that the Catholics that digest such
works will be torn from the True Faith and the narrow paths of
salvation.
It was modernism and liberalism that was swallowed by the majority
of Bishops lead by PVI that the Holy Office no longer protects the
dogmas of the Catholic Faith. And, abolished the Index of Forbidden
Books.
I really doubt that the Vatican had computers in 1964-65.
Everything was done the old fashioned office way.
Computers at that time where very large and only the big companies
could afford them and the maintenance were very costly.
