EWTN Catholic Q&A
Prefect for Congregation
Question from Allison on 04-21-2005:

Has the Holy Father appointed a prefect for the Congregation for the Doctrine of the Faith?

Answer by Colin B. Donovan, STL on 05-04-2005:

Not as of 4 May 2005. The Secretary of the Congregation, his former #2, Archbishop Angelo Amato, SDB, is currently in charge. Among the possible replacements for the former Prefect are: the former Prefect (popes have been known to head the doctrinal congregation themselves), the current Secretary, the former Secretary (Archbishop Bertone), and Cardinal Shoenborn, OP, of Vienna (who was the general editor of the Catechism).
