love this encyclical. it clearly and simply explained the Catholic Churches position on birth control. Every other religious organisation or church has accepted contraception / abortion.
Some church leaders seem afraid to even mention this part of church teaching , the silent treatment!!.
Pope Paul 6th and Vatican two were expected to comply with the modernists on this issue but Paul 6th took the decision to separate this topic away from the Curia , ( i think) , and then re affirmed the long standing biblical teaching in this beautiful encyclical.
