The Blessed John Paul II

I felt I was in Vatican to see the people waving their hands and their national flags to witnessed the beatification of the late John Pope Paul II, that became the Blessed Pope John Paul II. Everybody loved him. And would you believed that the chair where the Blessed Pope used during his Manila visit can be seen at the church where we served. I just didn't know what's the story behind that chair and why of all the churches, why in our church?
