"The truth expressed in Humanae Vitae does not change; on the contrary, precisely in the light of the new scientific discoveries, its teaching becomes more timely and elicits reflection on the intrinsic value it possesses."
- Pope Benedict XVI
"The teaching of Humanae Vitae...ought to be taken up anew in order to counter a mentality that is often hostile to life."
- Pope Francis
