One of the most radical changes presented in Praedicate Evangelium is that the laity, male or female, are now permitted to head the curial departments:

A key change is the elevation of the role of the laity in the governance of the Vatican Curia, and by extension, in the wider Church. “The Pope, the Bishops and other ordained ministers are not the only evangelizers in the Church,” reads the text. Therefore, the laity — male or female — must have “roles of government and responsibility,” orders Pope Francis.

Praedicate evangelium thus decrees that “any member of the faithful can preside over a Dicastery or an Organism, given the particular competence, power of governance and function of the latter.”

Such lay leaders for the Curia will be chosen insofar as they are “distinguished by spiritual life, good pastoral experience, sobriety of life and love for the poor, spirit of communion and service, competence in the matters entrusted to them, ability to discern the signs of the times.”

While I'm pretty much mostly against this change, part of me keeps thinking that the cardinals haven't been doing a bang up job running these programs for years.
