We continue this series from the last issue of the Catechetical Review here in the "From the Shepherds" department because of its reflections on the writings of the bishops of the universal Church.

The five decades between the Second Vatican Council and the publication of the third general catechetical directory in 2020 have been an extraordinarily important period in the history of modern catechetics.  During this time the Church’s catechetical ministry has been afforded unprecedented support in documents of the universal Church as well as those of the bishops of the United States. This series of articles is an exploration of those documents.  Prior to the Council, however, six pivotal international catechetical study weeks were convened that previewed some of the major concerns raised in the deliberations of the Council fathers.  In the first article of this series, the basic themes of the first three international catechetical study weeks held between 1959 and 1964 were explored. In this article, we will examine the issues engaged by the last three international catechetical study weeks held between 1964 and 1968.
