The author shows how the reform of the Roman Curia is a symbol for the reorganization of the Vicariate of the diocese of Rome, which took place with the apostolic constitution In Ecclesiarum communione, which in turn must be a symbol for the reorganization of the various diocesan curiae. The Church of Rome is presented as an evangelizing and missionary community, which must organize itself on the basis of the principle of synodality and participation. This becomes concrete in the importance that the apostolic constitution gives to the episcopal council, presided over by Pope himself or, in his absence, by the Cardinal Vicar, and composed of all the auxiliary bishops, who are called upon not only to express their own respective opinions but, beyond can. 473 §4, to give consent to the decisions of the Cardinal Vicar in the most important matters that are determined in the apostolic constitution itself. It is in fact considered the “primary organ of synodality” and the “highest place of discernment and of pastoral and administrative decisions”. In the spirit of synodality, in a consultative manner, all of the diocesan consultative bodies must also be involved in the most important decisions by the episcopal council.
