The word 'miracle' is often used to describe a variety of positive occurrences: a good day, a gorgeous sunrise, or the birth of a child.  These may be wonderful things, but a miracle as defined by the Catholic Church is a highly specific concept.  There is a process for determining whether or not a phenomenon qualifies, involving exhaustive testing and evaluation by the Vatican, scientists, and other experts.  At its core, a miracle is a way by which God is seen to interact directly with the world.  Fr Hightower joins us to examine how the Church views the Science of Miracles.
