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 "e;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"e; (NMI 30) is at stake. John Paul II stressed that a concrete "e;pedagogy of holiness"e; is required, including a "e;spiritual path,"e; without which "e;external structures...will serve very little purpose (NMI 43)."e; 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.
