  From October 1962, Wojtyła took part in the Second Vatican Council (1962–1965), where he made contributions to two of its most historic and influential products, the Decree on Religious Freedom (in Latin, Dignitatis humanae) and the Pastoral Constitution on the Church in the Modern World (Gaudium et spes). Wojtyła and the Polish bishops contributed a draft text to the Council for Gaudium et spes. According to the Jesuit historian John W. O'Malley, the draft text Gaudium et spes that Wojtyła and the Polish delegation sent "had some influence on the version that was sent to the council fathers that summer but was not accepted as the base text". According to John F. Crosby, as pope, John Paul II used the words of Gaudium et spes later to introduce his own views on the nature of the human person in relation to God: man is "the only creature on earth that God has wanted for its own sake", but man "can fully discover his true self only in a sincere giving of himself".
  
  Wojtyła also participated in the assemblies of the Synod of Bishops. On 13 January 1964, Pope Paul VI appointed him Archbishop of Kraków. On 26 June 1967, Paul VI announced Wojtyła's promotion to the College of Cardinals. Wojtyła was named cardinal priest of the titular church of San Cesareo in Palatio.
  
  In 1967, he was instrumental in formulating the encyclical Humanae vitae, which dealt with the same issues that forbid abortion and artificial birth control.
  
  According to a contemporary witness, Wojtyła was against the distribution of a letter around Kraków in 1970, stating that the Polish Episcopate was preparing for the 50th anniversary of the Polish–Soviet War.
  
  In 1973, Wojtyła met philosopher Anna-Teresa Tymieniecka, the wife of Hendrik S. Houthakker, professor of economics at Stanford University and Harvard University, and member of President Richard Nixon 's Council of Economic Advisers Tymieniecka collaborated with Wojtyła on a number of projects including an English translation of Wojtyła's book Osoba i czyn (Person and Act). Person and Act, one of John Paul II's foremost literary works, was initially written in Polish. Tymieniecka produced the English-language version. They corresponded over the years, and grew to be good friends. When Wojtyła visited New England in the summer of 1976, Tymieniecka put him up as a guest in her family home. Wojtyła enjoyed his holiday in Pomfret, Vermont, kayaking and enjoying the outdoors, as he had done in his beloved Poland.
  
  During 1974–1975, Wojtyła served Pope Paul VI as consultor to the Pontifical Council for the Laity, as recording secretary for the 1974 synod on evangelism and by participating extensively in the original drafting of the 1975 apostolic exhortation, Evangelii nuntiandi.
