St Jerome (c. 347 – 420)
Saw the book as a call to embrace the ascetic life in order to escape the vanities of this world. Strangely, he also says "the Hebrews says that ... this book ought to be obliterated, because it asserts that all the creatures of God are vain, and regards the whole thing as nothing, and prefers eating and drinking and transient pleasures before all things." Weird
Crenshaw (1987)
"life is profitless; totally absurd. The world is meaningless. Virtue doesn't bring reward. The deity stands distant, abandoning humanity to chance and death."
Ogden (1987)
"The book's thesis ... is that life under God must be taken and enjoyed in all its mystery."
Like any of these? Why not?
