A global canon law which considers the peculiarities of the local churches and their particular needs in the legislation and application of the law will be held responsible for fragmenting the ecclesiastical legal order and the church as such, which is a community of faith in a legal shape. Reducing the legal frame of the global church to the norms essential to secure the unity of faith, and establishing more local competences to create particular law and apply global law with a local flavour, weakens the idea of the universality of canon law. Nevertheless, in a plural church of different ecclesiastical cultures, it is questionable whether a more particularised approach to the law can be avoided. Safeguarding unity by uniformity risks losing legal effectiveness and validity, if it generates local incomprehension and alienation from the law. In this case, not much is won. On the contrary: Ignoring the essential historicity and culturality of each law and, thus, its necessary particularity, may lead to greater loss than gain. In order to protect the unity of the church, some uniformity in the field of Catholic canon law must be surrendered.
