There are many paradoxes in our Christian Faith. For example, there are three Persons in one God; this God made something out of nothing; God's mother is one of his creations, etc. It can be easy to respond by simply ignoring the discrepancies. But these paradoxes are not meant to be ignored. They are mysteries of our Faith, not meant to be kept secret, but to be unveiled by God himself.
One of the greatest mysteries of our Faith is that there can be profound joy even in the depths of the worst suffering, and this is the mystery that the Church draws to our attention on Gaudete Sunday. In the midst of a season of penance and waiting, we find ourselves celebrating a day completely devoted to joy!
