The author of the article tries to show that the Apostolic letters Tertio millennio adveniente and Novo millennio ineunte are a special expression of John Paul II’s involvement in promoting sainthood. First he examined the circumstances and the aim of proclaiming the above mentioned apostolic letters by the Holy Father, and then the Polish Pope’s reasons for expounding the teaching on sainthood. He also characterized the main motifs in this teaching. Finally he concluded that the results of the study clearly show that John Paul II was a great promoter of the idea of sainthood, and the analyzed documents may be considered a particular expression of the Pope’s involvement in the work of promoting the Church’s teaching on sainthood and of making it more profound.
