===Dutch Catechism===
The [[Dutch Catechism]] of 1966, based on the Dutch bishops' interpretation of the just completed Vatican Council, and the first post-Council comprehensive Catholic catechism, noted the lack of mention of artificial contraception in the council. "As everyone can ascertain nowadays, there are several methods of regulating births. The Second Vatican Council did not speak of any of these concrete methods{{nbsp}}[...] This is a different standpoint than that taken under Pius XI some thirty years ago which was also maintained by his successor{{nbsp}}[...] we can sense here a clear development in the Church, a development, which is also going on outside the Church."<ref>''A New Catechism'', pg. 402</ref>
