Final answer:
Jesus mentioned that his teachings could cause division among family members and also faced opposition from religious leaders, the Roman Empire, and Jewish authorities who saw his new interpretations and challenges to the social order as threatening.
Step-by-step explanation:
According to the New Testament of the Bible, Jesus said that those against him effectively included a wide range of individuals and groups. In passages like Matthew 10:35-36, Jesus speaks of division within familial relationships due to his teachings, suggesting that even a person's own household might become adversarial. Additionally, Jesus criticized the religious leaders and those in positions of authority, as seen when he was condemned to crucifixion for his radical ideas and challenges to the social order. At that time, the occupying Roman Empire viewed Jesus as a threat to their authority, as well as the established Jewish religious leadership. The Pharisees and scribes were also depicted as opponents of Jesus, often questioning his teachings and authority as demonstrated in the encounter with Levi and others regarded as sinners.
