During a research project aimed at understanding emerging trends in the Church in China, young Catholics emphasised the importance of fraternal ecclesial communities for faith development. They often refer to Christ as “Elder Brother Jesus,” echoing early Church Fathers’ views of Christ as the Brother who adopts believers into divine Fraternity through baptism. This concept resonates with Chinese cultural values. The thesis suggests that this Christological approach can help develop an ecclesiology of the Church as the Fraternity of Christ, aligning with the Acts of the Apostles and emphasising synodality based on Fraternity, as highlighted by the phrase “You are all brothers” (Mt 23:8).
