"But the essence of the matter is faith, not a (neutral) looking on or a desire to experience something (for oneself). One who snatches at psychological experiences (presumably perhaps "in the Holy Spirit") will reach into a void. And one who gropes for the flame will get burned by it. Faith is reverent; it allows the light space in which to burn. Still more: it receives from the light the eyes with which it sees the light. Si comprehendis, non est Deus*: and if you think to have grasped it, you are not one whom God has grasped...
Jesus has no need of apologetics: he shines through. He shines upon everyone who comes into the world (John 1:9) and does not deliberately look away (John 1:12). The Church should not pursue any apologetics for herself, but should instead endeavor to make her Lord visible."
-- Von Balthasar, "Does Jesus Shine Through?", Communio (1968), 319ff
* from St. Augustine, Sermo 52, 16: PL 38, 360; roughly translated: "If you understand, it is not God."
