Several days ago the Business Insider published a fascinating story: "Time To Admit It: The Church Has Always Been Right On Birth Control" by Michael Brendan Dougherty and Pascal-Emmanuel Gobry. Read it. You may agree with the exposition of the authors. Can't contradict experience. Recall: this publication is not connected with the Catholic Church.
Pope Paul VI continues to be vilified for teaching the beauty of sex is indeed Catholic, beautiful and reasonable, that the contraceptive mentality leads to a wrong, destructive end of humanity, that abortion is always wrong and that women should not be used as objects (e.g., porn).
Let those who have ears, hear.
