Blessed John Henry Newman (1801-1890), one of the great intellectual figures of the Catholic Church in the modern period, underwent in his life an arduous journey of faith marked by conversion from Anglicanism to Roman Catholicism. He is an author of an extensive literary work comprising sermons, spiritual literature, vast correspondence and various writings in theology, philosophy, history and education. This essay is devoted to the legacy of the English Cardinal. In addition to a biographical text, it strives to present a wholesome understanding of Newman’s life and work, reflecting on his peculiar mission within the Church. In the light of Hans Urs von Balthasar’s ecclesiological thinking, Newman’s distinct place in “Christological constellation” is seen in conjunction with the mission of St. John the Apostle, or “Johannine office” in the Church.
