Mystery

The fairest thing we can experience is the mysterious. It is the fundamental emotion which stands at the cradle of true art and science...A knowledge of the existence of something we cannot penetrate, of the manifestations of the profoundest reason and the most radiant beauty, which are only accessible to our reason in their most elemetary forms-it is this knowledge and this emotion that constitute the truly religious attitude.

- Albert Einstein

The Catholic faith, of course, is filled with mysteries, some of which relate to the life of Christ, the Virgin Birth, and the Resurrection, while others are concerned with those things that Christ has left us to help us on our way to salvation, especially the sacraments (which in the Eastern Church are referred to as mysteries). Christianity is indeed a religion of mystery. One must have a joy and reverence for the presence of mystery, without which Catholicism would become boring and even repulsive. Attempts to desacralize the sacraments in recent years are rooted in the loss of the sense of mystery. We speak often of the mystery of the Eucharist, but each of the sacraments is a mystery, although none of them is greater than the mystery of faith in the presence of Christ in the Holy Eucharist.
