This is the central point of departure between mainstream Christianity and Islam.
Mainstream Christian theology states that Jesus affirmed his equality with God through declarations of essential unity (such as 'I and the Father are one' in John 10:30) and by accepting divine worship. Conversely, secular scholars and Islamic theologians highlight passages showing functional subordination, such as John 14:28 ('the Father is greater than I'), arguing that the historical Jesus viewed himself as an exalted messenger entirely dependent on God's authority.
