The Hebrew people experience of a God-Shepherd, who walks, protects and leads to food sources, acquires visibility in the Good Shepherd Christian drawing up. Those care and donation ideas cross the shepherd-flock relationship and earns meaning from Diaconia. The Church s mission is crossed by the request of oblative service wich consists initself serving others. Therefore, the specific objective of this study is to analyze the Church diaconia from a case study: the diaconate. The Deacon, a sacrament by Christ the Servant, has his pasturing, occasionally, reduced to welfare and charitable purposes, in preference of their missionary and ministerial nature, thereby restricting the real meaning of his diaconia caritatis. Charity illuminates his pastoral action that is not restricted to mere benefi cence. His loving action is aimed at the good of the flock. A flock that is not his, but Christ s. A flock that does not gathers, since is not a shepherd as the priest, but wich herds in communion with the Episcopo and Presbyter. His ministry is therefore transverse. His pasturing connects and mediates altar and assembly serving Christ in the Word, in the liturgy and charity.
