Furtherm St. Bonaventure explains that God created all things “not to increase his glory, but to show it forth and to communicate it”, for God has no other reason for creating than his love and goodness: “Creatures came into existence when the key of love opened his hand.”
Sorry but you lost me.
I took the one (rabbi) to say the “meaning of our existence is completely beyond our comprehension,” while the other (Catholic catechism/Bonaventure) says “God shows forth and communicates His glory” and “He alone can impart true knowledge of the relationship of His creatures to Himself.”
I don’t disagree with the latter, as my knowledge of God which is real, though nor exhaustive, depends on Him giving me the ability to live and reason coupled with Him choosing to reveal Himself to me in ways I can understand.
