The research is carried out on the missional, ethical and horizontal dimension that flows from the Sacrament of the Lord s Supper in Lutheran theology, in a theological bias, dialogical and ecumenical perspective and with a particular interest in a pastoral application that affects the parish reality. In a time marked by an individualistic eucharistic praxis, uncompromised and unproductive from the point of view of the fruits of the sacrament, comes a search for the improvement of the liturgical-eucharistic spirituality directed towards the incarnated service of Christian charity in the world. Based on certain gap that is perceived in academic and ecclesial reflection on this relationship between the Eucharist and mission, particularly in the Brazilian Lutheran context, and on the intuition that there are enough elements in lutheran sacramental theology to be better used, this work poses the question: what kind of Eucharistic missionary spirit can be found in Lutheran theology? The research has a bibliographical methodology, with procedures for historical explanation and dialectical and progressive discussion. It starts from a contextualization of the Lutheran Reformation movement, assuming its intention to value the gospel and continues by unveiling Lutheran eucharistic theology, synthesized as the incarnate gospel. In an immersion in Luther s texts and other theologians of this tradition, the lutheran eucharistic missionarity is revealed in a powerful and fruitful call to the missional living of this gospel that intends to be incarnated horizontally. Finally, a pastoral proposal emerges for the benefit of the mission that flows from the altar to life, having the Evangelical Lutheran Church of Brazil as its focus. Along the way, gems of the bilateral dialogue between Catholics and Lutherans and of Catholic theology itself are considered.
