Reforms to the Statutes are foreseen in no. 181 of the text, which reserves both changes and the introduction of new provisions to the Holy See, at the request of the General Congress of Opus Dei.
When the initiative for the change is the Prelature’s, to guarantee the juridical certainty of the need for these changes, the Statutes stipulate that they be proposed and ratified in three General Congresses (no. 181, § 3).
Since, in this case, it is the Holy See itself that has requested proposals of modifications, it is not necessary to follow this procedure; the proposal can be made in one extraordinary congress.
