what does the bible say?
Monophysitism comes from the Greek words mono, meaning "only," and physis, meaning "nature." This belief teaches that Jesus had a single, combined nature during His life on earth. It contrasts with dyophysitism, the belief that Jesus has two distinct natures—fully human and fully divine. Monophysitism was rejected at the Council of Chalcedon in 451, where the doctrine of the hypostatic union was affirmed, declaring Jesus as both fully God and fully man in two distinct natures.
One of the major proponents of monophysitism was Eutyches, who taught that Jesus's divine nature overtook or absorbed His human nature. However, this view was officially condemned at the Sixth Ecumenical Council in 680–681. Biblically, the idea that Jesus had only one nature is incorrect. Scripture reveals that Jesus experienced both a human and divine nature during His earthly life (John 6:38; Hebrews 4:15).
