I analyze in this bibliographic research the Christian mystic as a promoter of human emancipation. The definition of Modernity as human autonomy is related to a supposedly fertile environment to generate atheists. This inference finds decisive obstacles. The emancipatory political theology may even begin in the mystical experience in which phenomena such as ecstasy and contemplation occur, however, it will only be complete if it promotes praxis, public social actions situated in history. Between atheists and mystics the possible link is the human emancipation. Hermeneutics, as Paul Ricoeur conceives it, is the methodological and theoretical framework adopted in this study. Modern atheism is described by the biographies and bibliographies of the masters of suspicion (Ludwig Feuerbach, Karl Marx, Friedrich Nietzsche and Sigmund Freud), while the meaning of mysticism is not found in the apologetic rhetoric, but in the witness expression of philosophers (Henri Bergson, Paul Ricoeur and Gianni Vattimo) and theologians (André Torres Queiruga, Jurgen Moltmann and John Baptist Metz). My findings are that the best definitions of faith are existential experiences, therefore, political theology is theology if it is mystical. The liveliness brought by experiencing the Holy Spirit leads to the praxis of following Jesus, in which the face of God is sought and the face of the neighbor is found.
