"He had a theory, Walt did, that the religious life, and all the agony that goes with it, is just something God sics on people who have the gall to accuse Him of having created an ugly world"

This quote by J.D. Salinger suggests that Walt had a theory that God punishes individuals who accuse Him of producing an awful world by providing a spiritual life loaded with pain. This might be analyzed as a warning to those who are important of God's development, as it indicates that they will be met suffering if they continue to reveal their discontent. It could likewise be seen as a reminder to those who are spiritual that their faith is a present from God, and that they should be grateful for it, in spite of the difficulties that include it. Eventually, this quote suggests that God remains in control which He will not endure criticism of His work.
