After many months of being busy, I decided it was time to make this a priority again. Welcome back to Heresy of the Week!
Audianism is a 4th century heresy with two main teachings: first, that God has a human form (an idea known as anthropomorphism, which refers to giving human qualities and characteristics to any non-human), and second, that Jesus’ death should always be celebrated during the Jewish Passover (on the date 14 Nisan in the Jewish calendar, also known as Quartodecimanism). While the Quartodecimanism practice was outlawed at the 325 Council of Nicaea, Audianists continued anyways. It soon died out, although it enjoyed a brief revitalization in 10th century Italy.
