Adoptionist heresy is the belief that Jesus Christ was not divine by nature but became divine at a specific point in time, often associated with his baptism or resurrection. This view implies that Jesus was merely a human who was adopted by God, contradicting the orthodox Christian teaching of the pre-existence and full divinity of Christ. This heresy played a significant role in shaping early Christian discussions about the nature of Christ and contributed to the historical development of Trinitarian theology.
