The understanding of our present time as a historical juncture that concerns all the spheres of human life and knowledge, is highly indisputable. Problems mainly discussed in the world also find their place within theological reflection. Nevertheless, in this context, these problems find new light when confronted with the message of the Master of Nazareth. The latter's typical response to the challenges of modern societies would neither be a religion of feeling nor a rationalistic religion, but a Christ-centred experience: "You have the poor with you always […] but me you will not always have" (Mk 14: 7). This nonconformist logic constitutes a real conundrum for modern societies, but remains, I argue, the original source of a theological discourse. This paper aims to analyse the theological status of Christian experience and to explore the reasons of its credibility in every era of history. It dialogues with some twentieth century theological reflections on "existential knowledge," inspired by the Ignatian legacy. One of these interlocutors and a prominent voice, Hans Urs von Balthasar, sustains a "total attunement" to Revelation in order to understand and correspond to God's being and will. This "higher centre" imposes a specific approach to issues such as social inequalities. The paper strongly emphasizes the fact that theological discourse often falls prey to the anxiety of being up to date. To be in a permanent listening of the numerous experiences of mankind that rightfully call upon the theologian may also blur the perception of Christian experience. It may equally generate an idea of reform, in the Church for example, with little or no theological grounding. These situations therefore call for a theological appraisal of the (im)possibility of Christian experience nowadays.
