Cardinal Jean-Marc Aveline of Marseille, known affectionately by supporters as John XXIV, is being positioned as a significant contender for the papacy. This nickname highlights his physical similarity to Pope John XXIII, a beloved figure among progressive Catholics noted for his efforts to modernize the Church.

Colosimo, a prominent French theologian, expressed confidence in Aveline’s potential, describing him as someone capable of bridging divides within the Church while firmly holding on to his identity. Now 66, Aveline has recently taken over as president of the French bishops' conference, where he has been instrumental in fostering interfaith dialogue in Marseille—a vibrant and culturally diverse port city facing numerous social challenges.

While not the most conventional choice among candidates, Aveline's strengths stem from his blend of openness to dialogue akin to Pope Francis and his extensive theological knowledge. However, historical patterns raise concerns, as French candidates have rarely found favor in papal conclaves since the 14th century due to the legacy of the Avignon papacy.

Adding to the hurdles is Aveline’s limited familiarity with the Vatican's internal workings, as well as his lack of fluency in Italian, the prevalent language for daily communications at the Holy See. Despite these challenges, supporters remain hopeful that his fresh perspectives can honor the rich traditions of the Church while embracing the complexities of modern faith and society.
