>>17810400>by his new ideas for paganism weren't popular with other pagansHe didn't have much new ideas. Even how he critiqued Christianity was steeped in the same ideas which existed in the past relating to cultural critique alongside the newer ones emerging from Church struggles. Julian as a philosopher was a bog standard Neo-Platonist and how he treated official cults was in a normal way. The only thing he did which was seen as strange was his excessive desire for animal sacrifices, which had already been on the decline before Christianity and he was disappointed when he saw active local cults no longer practice it.
>>17810850>Unified pagan church (IE coping the christian church system)While he very clearly admired it for the administrative and organisational power it had as he writes to a friend, he never actually acted to implement anything like it.
>(like mass blood sacrifices)This is a Christian trope and doesn't actually relate to any pagan practice even beforehand.
>All pagan cults were aspects of his solar neoplatonic monotheistic personal faithThis isn't really that strange. Platonic philosophers have always had this bend towards divinity. While his personal intellectual thoughts of religion did follow this he didn't really treat pagan cults any differently because of it. He was a major patron and defender of popular ritual and festivals .
