I believe that Jesus started his first and only Church, which is the Catholic Church.  I agree that Jesus wants all to join his Church, which I also want all to convert to the one true faith.  There are great differences between the Catholic Church and the other Protestant Churches.  The seven sacraments and the devotion to our Blessed Mother being the most obvious and important. One Church is correct in its teachings and the other are wrong.  I obviously believe the correct one is the Catholic faith.
