Final answer:
Christians in Rome were viewed with suspicion because their monotheism, refusal to worship emperors, and evangelical efforts stood in contrast to Roman religious traditions, leading to persecution by authorities such as Nero. Over time, however, Christianity grew in influence, eventually becoming the state religion.
Step-by-step explanation:
Why Christians Were Viewed with Suspicion by Romans
Christians were regarded with suspicion by Romans for several reasons. Their strict monotheism and refusal to worship the Roman emperors as deities positioned them in opposition to the traditional Roman religious practices, which included worshipping multiple gods and deifying emperors. The evangelical nature of Christianity made it appear more subversive as it actively sought to convert others, unlike the more insular practices of Judaism from which it originated.
Roman authorities viewed Christians as potential disruptors of the societal hierarchy. Emperor Nero famously blamed Christians for the Great Fire of Rome in 68 CE, leading to severe persecutions. The perception of Christianity as treasonous was further entrenched by their refusal to partake in the imperial cults which were seen as vital for state stability.
Over time, as the religion grew in influence and spread across the empire, instances of violence and persecution increased, including during the reigns of Emperors Decius and Diocletian. However, Christianity eventually gained acceptance through Constantine's conversion and later became the state religion under Theodosius I, leading to the waning of traditional Roman polytheism.
