The Ius Legationis of the Roman Pontiff and Its Role in the Church’s Mission: In the light of the CIC/83 can. 362

The ius legationis of the Roman Pontiff, rooted in the earliest centuries of the Church, stands as one of the most profound and debated institutions of canon law and ecclesial governance. This volume offers a rigorous study of papal legation, examining its juridical foundations, theological and missionary significance, and diplomatic dimensions. Drawing on biblical, historical, theological, and canonical sources, it addresses enduring questions concerning the sovereignty of the Holy See, its international personality, and the relationship between papal authority and episcopal ministry. Far from being an ＂anachronism,＂ papal legation is revealed as a vital instrument of ecclesial communion and a distinctive contribution to international relations. Above all, it is inseparably bound to the supreme purpose of the Church - the salus animarum. Animated by Christ’s command - ＂Go, teach and baptise＂ - papal diplomacy strengthens communion, defends human dignity, and fosters peace, ensuring its enduring relevance as a spiritual service for the Gospel and the salvation of souls.
