A eclesiologia batismal do Concílio Vaticano II

Abstract

This dissertation in Theology explores the baptismal dimension as the foundation of ecclesiology and ecclesial praxis. Inspired by the pastoral theme proposed by Bishop José Ornelas for the Diocese of Leiria-Fátima — “Through Baptism we are a living and pilgrim Church” — and by the synodal process promoted by Pope Francis, it seeks to show that Baptism is the root of ecclesial communion, participation, and mission. The analysis of ecclesiological development between the First and Second Vatican Councils, with a particular focus on paragraph 10 of Lumen Gentium, reveals that the common priesthood of the faithful and the ministerial priesthood, though distinct in essence, both share in the one priesthood of Christ. This relationship expresses the structure of ecclesial communion and restores to Baptism its central place as the source of dignity and co-responsibility within the Church. The study concludes that synodality represents the contemporary expression of baptismal ecclesiology, calling the Church to live as a communion of the People of God on the way, where all the baptized actively participate in the life and mission of the Church.
