In his "On the Beatitudes," an excerpt of which is today's patristic reading for Vigils, Gregory of Nyssa writes:
In our human life bodily health is a good thing but this blessing consists not merely in knowing the causes of good health but in actually enjoying it. If a man eulogizes good health and then eats food that has unhealthy effects, what good is his praise of health when he finds himself on a sickbed? Similarly, from the Lord's saying: Blessed are the pure of heart, for they shall see God, we are to learn that blessedness does not lie in knowing something about God, but rather in possessing God within oneself.
For those who think that Catholic Faith is all "ritualism" (whatever that is!), here is an Orthodox Catholic Father from the 5th century to show us yet again that Catholic Faith is not all about doing stuff, or knowing stuff, but about being in a relation with Christ. I get so tired of hearing "evangelists" scream that Christianity isn't a religion but a relationship! You don't need to tell us, buddy. We've been there, and we've done that, and we're still at it. Two thousand years of faith and faithfulness---we know what we're doing.
