Robert De Mattei, Rorate Caeli: The ultimate criteria of judgment for a Catholic must be the one of the Church: to love and hate what the Church loves and hates: loving the truth in all of its uniqueness and integrity and hating error in all of its multiplicity of expressions.

In 1542, Pope Paul II, instituted the Congregation of the Roman Inquisition, afterwards called the Holy Office and nowadays named the Congregation for the Doctrine of the Faith, with the aim of guarding the purity of orthodoxy. In 1571, Saint Pius V, supported it with the Congregation of Index which had the task of indicating all the books deforming correct Catholic Doctrine. In 2002, L’Index Librorum prohibitorum 1600-1966 was published by the Centre d’Études de la Renaissance at Sherbrooke University, and gathers together all of the condemned works until the suppression of the Index, which Paul VI wanted in 1966.
