Moralism can make you a slave to parental expectations. The two ways you become a slave under moralism is that either you are so bound to please your parents that you can’t live without continually thinking of them, or you are so mad at them for their control or neglect of your life that you cannot live without thinking of them. To be living either in action OR reaction to them all the time means that you are still a slave to their view of you. You are haunted by it either way. On the other hand, hedonism sees no need for family loyalty or the keeping of promises and covenants if they do not ‘meet my needs.’
The gospel frees you from making parental approval an absolute or psychological salvation, pointing out how God becomes the ultimate father. Then you will be neither too dependent or too hostile to your parents.
