The initial article of the Symbol of Faith «I believe in God, the Creator» has been commented upon by John-Paul II in his 1986 Wednesday audiences. Also in the various official catechisms published from 1987 to 1992. The present article points out in this teaching aspects of peculiar interest to a modern intelligence aware of recent scientific discoveries. These discoveries seem to have partially inspired successive catechetical presentations, in particular that by John-Paul II and that found in the newly appeared Catechism of the Catholic Church.
