The Catholic Church has always opposed abortion, but--contrary to popular belief--not always for the same reasons. This tightly argued, historically grounded study sets out to demonstrate that a "pro-choice" stance, now held by a significant minority of Catholics, is as fully justified by Catholic thought as an antiabortion view. A Brief, Liberal, Catholic Defense of Abortion argues that the current Catholic antiabortion stance is justified neither by modern embryology nor by ancient church teachings. Combining up-to-date information on fetal development with a thorough grasp of the works of the church's early thinkers (such as Sts. Augustine and Thomas Aquinas), Daniel A. Dombrowski and Robert Deltete expose crucial contradictions between the early and the modern Church's views of abortion.
