In his inaugural encyclical Ecclesiam suam in 1964, Pope Paul VI had already described respectful dialog as an essential basic attitude and authentic path for the Church in the face of contemporary social developments: "The Church must enter into a dialogue with the world in which it now lives" (ES 67) Building on this, dialogue is a central motif in many of Pope Francis' texts. (Steinmair-Pösel, 2020) As early as 2014, in a private audience with Alexis Tsipras, Walter Baier and Franz Kronreif, he emphasized the importance of a transversal dialogue: only in this way could the great current problems of humanity be solved. This conversation gave rise to the DIALOP initiative - a dialogue project between left-wing/socialist/Marxist and Christian thinkers. (Baier et al., 2020, p. 2) In keeping with the attitude and working method developed in this project, my colleague Angelina Giannopoulou from the leftist side and I as a Christian social ethicist in this panel will be organizing our papers not monologically, but dialogically. In this way, we want to let the participants share our dialogue experience to a certain extent. I will start our dialogue by highlighting some of the pressing social problems of the EU seen through the lens of Catholic Social Teaching in order to open the conversation about common problem assessments and diverging interpretations. In a second step we will - referring to foundational documents of the DIALOP group - revisit more systematically some points of shared convictions as well as major differences. (Brie & Callebaut, 2022) In a third step I will talk about my own experiences of dialogue in the DIALOP group and explain why and how these are in line with Pope Francis' repeated calls for dialogue. In this context, we will also explain the methodology developed in the DIALOP project. (Kronreif, 2020) Finally, against the background of Catholic Social Teaching, I will argue in favor of multi-perspective approaches in social ethics.
