Final answer:
A courtier dealing with scriptures should interpret and apply sacred texts as moral guides, use them supportively in debates and judgments, and ensure they're in line with historical religious practices and legal precedents.
Step-by-step explanation:
When a courtier is dealing with scriptures, it is expected that they will carefully select and interpret biblical or sacred texts as a guide for moral and ethical leadership, particularly in advising a king or ruler. The use of scriptures is essential in supporting positions on various matters, with historical accounts demonstrating the value of quoting revered texts, similar to how the Sophists used epic tales and poems to argue effectively in debates. Furthermore, in matters of legal disputes and judgment, as shown in the teachings of Aelius Tubero and Marcus Cato, scriptures along with moral character would often inform the rulings in the absence of documents or witnesses.
Courtiers were to follow the precedence of religious and legal authorities, as indicated by decrees and decisions historically made to maintain religious practices in accordance with traditions and to prevent the subversion of religion. Throughout history, the interpretation of scriptures and their applications have had profound implications in governance, suggesting that a courtier should draw upon these texts judiciously, with the understanding that moral guidance, the authority of law, and tradition were closely intertwined in steering the moral compass of a ruler and society.
