By Richard A. Spinello, The Catholic Thing - Since the Pontifical Academy for Life (PAL) was restructured several years ago by Archbishop Vincenzo Paglia, it has been mired in a series of high-profile scandals. The most recent controversy surrounds the publication of The Theological Ethics of Life. Woven into this book are proposals for modifying doctrines such as the prohibition against medically assisted procreation. The book also questions the teaching of Humanae Vitae, which forbids the use of contraceptives.
