The nation of Poland has a rich Catholic history but also one of tremendous persecution. Throughout these periods of strife the people have remained devoutly Catholic. Of course no one can dispute the effect that one Polish priest had on the world: Saint (Pope) John Paul II. His Pontificate helped launch what was certainly one of the most significant events of the 20th Century. But there is more to see in Poland as well, including the famous Shrine of Divine Mercy. It was Saint John Paul II who was instrumental in making the Sunday following Easter Divine Mercy Sunday.
