Recommended Book: Abortion, the Development of the Roman Catholic Perspective
I bought a book by John Connery, SJ titled Abortion, the Development of the Roman Catholic Perspective, which I have found extremely helpful and an excellent resources for later reference. This book was written in 1977 a few years after Roe v. Wade. With this historical survey, Connery wanted to show how the position of the Church on abortion was not adopted from one day to another but that rather it has its foundations since pre-Christian times in the Jewish tradition. Connery covers the positions on abortion from Jewish times up to modern times–including the early Church fathers and medieval and reformation periods. Absolutely excellent!
