On this edition of What Catholics Believe, Tom and Fr. Jenkins discuss:  What is the difference between the active will of God and the passive will of God?  • What is the ‘Oath Against Modernism’?  • Is the ‘Oath Against Modernism’ binding upon successive popes?  • Can an encyclical be overturned by a later pope?  • Was Vatican II the result of God withholding his graces?  • What was the Miracle on the Vistula?  • How was ‘Humanae Vitae’ a restatement of previous Church teachings?  • How was ‘Humanae Vitae’ also different from previous Church teachings?  • Why do the members of the Novus Ordo have a myriad of views on morals?  • Lastly, Fr. Jenkins shares a few spiritual thoughts on preparation for the season of Advent.
