text: Secretaries since 1965 With the December 1965 reorganization of the Holy Office as the Sacred Congregation for the Doctrine of the Faith, the head of the Congregation was no longer titled Secretary. The dicastery's second-in-command, until then titled assessor, was then given the title of Secretary, as was already the case with the other Roman Congregations. All but the most recent have been made archbishops upon their appointment. The following have held the title of Secretary:
  Pietro Parente (7 December 1965 – 29 June 1967)
  Paul-Pierre Philippe, O.P. (29 June 1967 – 6 March 1973)
