I’ve excerpted chapters from my theology books and put them online as free ebooklets in PDF format on a few different topics:
1. On Speculative Theology and Eschatology (32 pp.)
This booklet distinguishes between infallible dogma, non-infallible doctrine, and speculative theology. The usefulness of all three are explained. Then there is a lengthy discussion of the speculative nature of most eschatology (theology about the future), including my own work in the field.
2. The Immorality of Pornography (25 pp.)
Pornography is causing grave harm to society, to marriages, and to children. There is no way to keep porn widely available to adults, and exclude teens (and even some preteens) from exposure to this material. This booklet considers the problem of pornography from the point of view of Roman Catholic ethics, including the teaching of the Catechism of the Catholic Church.
3. The Marital Sexual Act (45 pp.)
This booklet is excerpted from my book Roman Catholic Marital Sexual Ethics. The discussion centers on the morality of natural marital relations open to life, and the immorality of all other sexual acts, even within marriage. The various excuses that people use to justify unnatural sexual acts within marriage are refuted.
