Pontifical Commission on Birth Control

"It has been said that a couple who use the infertile period have intercourse at that time precisely to prevent the beginning of a new life. Their positive means are the use of a thermometer and the charting of temperatures. But this objection is nugatory."

The overwhelming majority in the Pontifical Commission on Birth Control concluded that artificial birth control did not violate the Church’s teachings, and that Catholic couples should decide for themselves what methods to use. However, a Jesuit theologian wrote a dissenting report.
