ὄνομα

The Greek word ónoma, most often translated "name," carries significant theological weight in the New Testament. Beyond simply identifying a person, "name" in ancient thought, and especially in Scripture, often encapsulates the very essence, character, and authority of the one named. To act in someone's name is to act on their behalf, with their authority and character backing the action. This is particularly crucial when referring to the "name of God" or the "name of Jesus."

When Jesus instructs his disciples to ask in his name (John 16:24) or promises that wherever two or three are gathered in his name, he is there (Matt. 18:20), it points to his divine presence and authority. It signifies more than a mere utterance of his title; it means to approach God based on who Jesus is, in union with his character and purposes. Similarly, those who believe in Jesus' name (John 1:12) are those who trust in his person and work. To come "in the name" of another (John 5:43) is to claim to represent them or their authority.

The emphasis on the "name of Jesus" is foundational to Christian faith and practice. Miracles are performed, demons are cast out, and salvation is proclaimed through his name. The phrase "for my name's sake" (Matt. 19:29) indicates that actions are undertaken because of allegiance to Christ and in devotion to his person. The concept of having one's "name written in the book of life" (Phil. 4:3) beautifully conveys the idea of being eternally known and identified with God's people.
