The first novelty lies in the presentation of the historical, theological and methodological arguments on asserting the Liberation Theology as Practical Theology. Indeed, the Practical Theology, as that one originated in northern Europe, and thought in the French context, it is still new in the Latin American context. The second novelty is the presentation of the French author Henri Bourgeois (1934-2002). Bourgeois joins two essential characteristics in his work: he is one of the representatives of the French Practical Theology and deep connoisseur of its theological formation and doing, beyond the fact that he knows, in practice and theory, the Liberation Theology. Combining these two aspects, we find in his thought the defining criteria for a Theology to be considered effectively as Practical Theology, and, taking into consideration the methodological perspective, what was the contribution from the Liberation Theology to the French Practical Theology. Therefore, we organized our text into three parts. The first part will deal with main bibliographic and theological data regarding Bourgeois. In the second part, we presented the methodological elements of the Liberation Theology, so that, finally in the third part, we present the theological linking between the two theological currents/trends.
