Page "Humanae Vitae" Paragraph 13

According to George Weigel's biography of John Paul II, Paul VI named Archbishop Karol Wojtyła ( later Pope John Paul II ) to the commission.

However, the Communist authorities in Poland would not permit him to travel to Rome to take part in person.

Wojtyła had earlier defended the church's position from a philosophical standpoint in his 1960 book Love and Responsibility.

Wojtyła's position was strongly considered, and was reflected in the final draft of the encyclical, although much of his language and arguments were not incorporated.

Weigel attributes much of the poor reception of the encyclical to the omission of many of Wojtyła's arguments.
