As a leadership community within the School of Leaders, the Diocesan Secretariat must always see itself as being of service to the whole movement. The Secretariat gives life to the Movement in its three phases: Pre-Cursillo, Cursillo and Post Cursillo. Authority to do so comes from the local bishop who charges the Secretariat to implement the movement according to the norms and guidelines established by the National Secretariat. (Leader's Manual)
Members of the Secretariat for the Filipino Cursillo Community consist of the following: Lay Director, Spiritual Advisor, chairpersons of the School of Leaders, Pre-Cursillo, Cursillo, Post Cursillo, Secretary, Treasure and Communications Administrator.
