This paper talks about two dimensions of Church-reality: divine and human, defined by the Second Vatican Council (1962-1965) as People of God. The church is divine because it has its origin in God and human because God swill is manifested in the hearts and minds of the people. We focus our thinking, especially about the relevance and challenge of the sensus fidei in the dogmatic Constitution Lumen Gentium of Vatican II. The divine plan is Yes of God s unconditional love, offered to humanity, and faith of the human being is amen of his spontaneous opening, the inner attitude of surrender to grace. The awareness of faith is the necessary road, the core element of the construction and constitution of union communial and communication relationship of humanity with each other, the cosmos and with God. The reality of non-ordained people and their experience of God in the post-Vatican II became for the new scenarios of the Church. Besides the diverse attitudes towards the reception of the Council, there are also various interpretations of approaches of the post-conciliar Church. Our research aims to analyze the constitutive element (sensus fidei) of the Church, using theological sources, such as: Holy Scripture, Tradition and Church Magisterium.
