Under his guidance the Church moved closer to the third millenium and celebrated the great Jubilee of 2000, following indications in the apostolic letter Tertio millennio adveniente. His leadership brought us to the new era taken from indications from the Apostolic letter Novo millenio ineunte, the letter in which he showed the faithful the path of the future.
With The Year of Redemption, the Marian year and the Year of the Eucharist he promoted the spiritual renewal of the Church. He gave an extraordinary push to canonization and beatification, to show the vast number of examples of sainthood today to serve as an example for men today. He proclaimed Saint Theresa doctor of the Church.
The doctrinal teaching of John Paul II is very rich. Custodian of faith, he worked with knowledge and courage to promote the catholic doctrine, moral and theological doctrine and he contested throughout his entire Pontificate the things which went against the genuine tradition of the Church.
Among his principle documents are 14 Encyclicals, 15 Apostolic Exhortations, 11 Apostolic constitutions, 45 Apostolic letters, as well as the catechisms that he proposed during his general audiences and the sentences he pronounced in every part of the world. With his teachings John Paul II illuminated the people of God with his theological doctrine (most of all with his first three most important encyclicals -- Redemptor Hominis, Dives in misericordia, Dominum et Vivificantem), social anthropology (Encyclical Laborem exercens, Sollictudo rei socialis, Centesimus annus) moral (Encyclical Veritatis splendor, Evangelium vitae), echumenical (Encyclical Ut unum sint), missionary (Encyclical Redemptoris missio) and mariologicol (Encyclical Redemptoris Mater)).
He promoted the Catechism of the Catholic church, in light of the Tradition, authoritatively interpreted by The Second Vatican Council. He also published a few volumes as a private theologian.
His teaching culminated with the Encyclical Ecclesia de Eucharistia and with the Apostolic letter Mane nobiscum Domine, during the year of the Eucharist.
John Paul II has left us all a testimony of admirable piety, a holy life and of universal fatherhood.
