Someone who actively opposes or contradicts apostles or their teachings.
From Greek 'anti-' (against) + 'apostle' (from 'apostolos' meaning messenger or one sent out). The term is rare and emerged mainly in religious discourse to describe opponents of Christian teaching.
While historians debate what apostles actually taught versus what was written down later, calling someone an 'antiapostle' was a serious insult in early Christianity that sometimes got people in real danger.
