Risking the word in the pulpit, in one's life, in the work of an entire life. According to Vieira, from the Sermons to the History of the Future, the word makes a way for itself. Besides of the rhetoric artifices and the politico-religious conveniences, Vieira establishes the action bases as response to the God's word, and in fidelity to the same by adopting as paradigm the History of Israel, a revealing, and always the first one, History of the God's initiative. A History that also reveals the right paths and the wrong paths of the human response, of the historic responsibility that such a response holds. When Vieira proposes the reading of the way God works, of the alliance of God with the humankind, Vieira dangerously aligns himself with the row of those who make trouble. Vieira reminds the impossibility of sheltering oneself under the concept of election. The purification of this concept, as well as the concept of 'being Christian' is unpostponable. Nevertheless, the Vieira's position is not free from theological issues. The risk of his word that opens this debate equally indicates to the man the reasons for hoping and believing in the promise, the key for reading the future. [ABSTRACT FROM AUTHOR]
