Ecce Educatrix Tua discusses the Apostolic Letter Novo millennio ineunte (NMI), wherein John Paul II outlined the path the Church should adopt in the third millennium. The necessity "to rediscover the full practical significance of Chapter 5 of the Dogmatic Constitution on the Church Lumen Gentium, dedicated to the universal call to holiness" (NMI 30) is at stake. John Paul II stressed that a concrete "pedagogy of holiness" is required, including a "spiritual path," without which "external structures...will serve very little purpose (NMI 43)." The Polish Pontiff invited ecclesial movements to present their original pedagogy of holiness (cf. NMI 31). Peters highlights the Blessed Virgin Mary as educator in a pedagogy of holiness from the teachings of John Paul II and Father Joseph Kentenich, founder of the Schoenstatt Movement.
