Final answer:
In the parable of the prodigal son, the loyal son is assured by his father that his inheritance remains with him, reflecting both the legal and cultural expectations of the time regarding family responsibility and filial duty.
Step-by-step explanation:
In the parable of the prodigal son, the loyal son is to be left with his inheritance. This is grounded in the cultural context of the time, where family responsibility and maintaining the family's reputation and prosperity were paramount once a son inherited his father's property, including his debts.
According to the laws of inheritance prevalent in ancient societies, the older brother often received a double portion. In the case of the prodigal son parable, although the younger son squandered his share, the father reassures the loyal son that all he has will be his, which implies not just the remaining inheritance but the entire patrimony, as the younger brother has already taken his share.
By aligning with the constructs of filial piety, as highlighted by Confucius, the parable also teaches about the importance of the duty of the son to respect and abide by his father, which the loyal son exemplifies through his obedience and steadfastness in contrast to the prodigal son.
