I started reading Bryan Hodge's A Christian Case against Contraception. So far, so good. Hodge examines contraception in light of the four disciplines of theology. Beginning with an historical perspective of the Church toward preventing conception, Hodge makes the argument, as the title of the book suggests, that contraception is sinful. He then moves to an exegetical look at procreation and contraception in the Scriptures, a systematic look at contraception, and a practical look at issues of contraception. So far, I'm only into the exegetical section, but the look at contraception in the history if the church was pretty good.
Inasmuch as an opposition to contraception was nearly universal in the Church until 1930, the burden of proof to demonstrate that contraception is an acceptable avenue for Christian married couples falls to the pro-contraception crowd.
Here's my challenge: pony up; get the book; read it; and let's discuss it. Email me if you'd rather not make a public answer to the book but would still be interested in the dialogue. I genuinely want a fraternal--not an antagonistic--discussion. Takers?
