Historical sources will obviously vary from episode to episode.  For the most part, the cartoons will rely on commonly known facts, as understood by Catholics.  However, the writings of Popes, Saints and other sources that have been accepted throughout Catholic history will also be used from time to time.  "Glorious Heritage" cartoons seek to portray the history of the Catholic Church in a simple way, yet remain edifying for young children.   Adherence to Catholic Tradition is of paramount importance in our efforts to produce these cartoons!
