On 11 October 1992, presented Pope John Paul II the faithful throughout the world Catechism of the Catholic Church, which he characterized as "a reference text for a catechesis renewed out of faith living sources". Thirty years after the opening of the Second Vatican Council (1962-1965) became the desire that the Extraordinary Synod of Bishops had uttered in the year 1985, namely to draw up a catechism for all the Catholic religious and moral teachings, met. Five years later confirmed the Holy Father the basic objective of the work: "To offer a complete and pure representation of Catholic doctrine, making it possible for everyone to get to know what the Church in their daily lives professes, celebrates, lives and pray ". Catechism consists of 2,700 sections that detail describing and explaining the Catholic faith. Footnotes referring to the Bible, the Church Fathers and ecclesiastical documents.
This version of the Catechism app uses catechism texts published in Issue 2, St. Olav Publishing 2014.
