Docetism: In the early church, the teaching that Jesus was fully God but only appeared to be human (taken form the Greek dokeō, “to seem or appear”). Docetist theologians emphasized the qualitative difference between God and humans and therefore downplayed the human elements of Jesus’ life in favor of those that pointed to his deity. The early church rejected docetism as an heretical interpretation of the biblical teaching about Jesus.1
