"Since some have subsequently held that after the abrogation of the Index, the printing and diffusion of the Work in question is licit, L'Osservatore Romano (15 June 1966) had presented what was published in A.A.S. (1966) [Acta Apostolicae Sedis]: that, although abolished, the "Index" retained "all its moral value," for which [reason] the diffusion and recommendation of a Work is not held to be opportune when its condemnation was not taken superficially, but after weighing its purposes, to the end of neutralizing the damages which such a publication could bring to the more unprepared faithful." http://www.bardstown.com/~brchrys/Chrchval.html
"To respond to the above-mentioned questions, this Sacred Congregation for the Doctrine of the Faith, after having asked the Holy Father, announces that the Index remains morally binding, in light of the demands of natural law, in so far as it admonishes the conscience of Christians to be on guard for those writings that can endanger faith and morals. But, at the same time, it no longer has the force of ecclesiastical law with the attached censure. A Hittani Kongregáció állásfoglalása, 1966 jún. 14.
