What was a significant change in religious practice under Julian the Apostate?

The significant change in religious practice under Julian the Apostate was the attempts to integrate Christian and pagan practices. Julian, who ruled from 361 to 363 AD, is often referred to as "the Apostate" because of his efforts to revive traditional polytheistic beliefs and practices in opposition to the growing influence of Christianity.

During his reign, Julian sought to re-establish paganism and often promoted a philosophy that encouraged the merging of various religious practices. He believed that by integrating aspects of Christianity with pagan rituals, he could create a more harmonious society and diminish the stark divide between the two faiths. This approach was evident in his policies and public declarations where he emphasized the importance of traditional pagan festivals and rituals, while simultaneously attempting to appeal to Christian sentiments.

This integrationist strategy was part of Julian's broader objective to reinvigorate the ancient religions of Rome and curb the power of the Christian church, which had rapidly gained followers and influence in the Roman Empire. His efforts reflected a unique moment in history where the tension between the old and new religious paradigms was palpable, showcasing his belief in a pluralistic religiosity that would encompass both pagan and Christian elements.
