In Platonic dialogues, for example, a ‘critical’ edition — even if research results sometime in a single and certain text — may have a priority, since Plato alone is the criterion of the genuineness of the text. If the criterion of authenticity lies in Church life, because the Church decided even the identity of the authors, only the Church can really discern the valid text, in a judgment that extends in centuries of a whole tradition of collective understanding.

‘Critical’ editions can contribute possible variations of meaning, perhaps even equally important alternative meanings — however, the text that is formed and shared in the tradition of the Church is always the most important and authoritative.
