Times have changed.
Fundamentalist proselytism is obvious and everywhere and now constitutes a worldwide epidemic.
Darkness exists only where there is no light, and error advances only where there is ignorance. Unfortunately, with the worldwide collapse of effective Catholic catechesis and the confusion and denials spread by Modernism and Progressivism, there is today much ignorance. Thanks be to God, there is a growing number of Catholics who are no longer prepared to see the Church of Christ remain defenseless in the face of the untruths, distortions and historical inaccuracies of sectarians and other opponents. Hence, the formation in recent years of various lay apostolates specializing in apologetics, particularly in the United States. Each topic is complete in itself, and is designed for use by teachers or instructors of adult catechetical, apologetical, religious or home groups.
