The term MesoPagan was first put forth by Isaac-Bonewits in an attempt to categorize modern Paganism.
According to Bonewits, MesoPagan religions developed from PaleoPagan or native Pagan religions that were influenced by Monotheistic, dualistic or Nontheistic philosophies.
These include all syncretic religions including Christo-Paganism, many Afro-Diasporic faiths, such as Voodoo, Santeria and Candomble.
Also, some Satanic traditions could fall into this category.
The definition of MesoPaganism is nearly identical with that of syncretism, a word that enjoys common use in academic circles, when it is applied to any Pagan religion.
