The ministry of catechesis draws ever fresh energy from the councils. The Council of Trent is a noteworthy example of this. It gave catechesis priority in its constitutions and decrees. It lies at the origin of the Roman Catechism, which is also known by the name of that council and which is a work of the first rank as a summary of Christian teaching and traditional theology for use by priests. It gave rise to a remarkable organization of catechesis in the Church. It aroused the clergy to their duty of giving catechetical instruction. Thanks to the work of holy theologians such as St. Charles Borromeo, St. Robert Bellarmine and St. Peter Canisius, it involved the publication of catechisms that were real models for that period. May the Second Vatican Council stir up in our time a like enthusiasm and similar activity.
The missions are also a special area for the application of catechesis. The People of God have thus continued for almost 2,000 years to educate themselves in the faith in ways adapted to the various situations of believers and the many different circumstances in which the Church finds herself.
Catechesis is intimately bound up with the whole of the Church’s life. Not only her geographical extension and numerical increase, but even more, her inner growth and correspondence with God’s plan depend essentially on catechesis. It is worthwhile pointing out some of the many lessons to be drawn from the experiences in Church history that we have just recalled.
