Catechism of St. Pius X (Trial

Catechism of St. Pius X (Trial Version)

Catechism of St. Pius X was recommended by St. Pius X when he was still an archbishop.

In 1905, Pius X in his letter Acerbo Nimis mandated the existence of a catechism class in every parish in the world.

The Catechism of Pius X is his realisation of a simple, plain, brief, widespread catechism for uniform use throughout the world. It was used in the Vatican Rome and other parts of Italy. It was not, prescribed for use throughout the universal church.

The Catechism of Saint Pius X was issued in 1908 in Italian.

Asked in 2003 whether the almost 100-year-old Catechism of Saint Pius X was still valid, Cardinal Joseph Ratzinger said: "The faith as such is always the same. Hence the Catechism of Saint Pius X always preserves its value. Whereas ways of transmitting the contents of the faith can change instead. And hence one may wonder whether the Catechism of Saint Pius X can in that sense still be considered valid today."
