The answer is: Holy One of Israel

Isa 7:14 - Immanuel; John 8:12 - Light of the World; Isa 9:6 - Prince of Peace. The Holy One of Israel was only ever used of God.

When we think about the titles of Jesus, there’s a treasure trove of meanings and roles that reflect his influence in the New Testament and beyond. Exploring these names can give us insight paradoxically straight from the Old Testament. The title “Holy One of Israel” brings to mind the rich Jewish tradition where it was frequently associated with God Himself, emphasizing His holiness and separation from sin.

In scripture, the term “Immanuel,” which means “God with us” (Isaiah 7:14), certainly sets a powerful tone of divine presence through Jesus, contrasting with conventional understandings of authority and power. It whispers to us about accessibility and intimate connection.

The 'Light of the World' title from John 8:12 is quite illuminating in character! It signifies not only guidance and wisdom but also represents revelation and truth—a theme echoed in many writings of various spiritual traditions throughout history.

And let's not forget the 'Prince of Peace' (Isaiah 9:6) adding layers of significance—a role embodying mediation and reconciliation, advocating for peace amidst stormy times.

In a broader perspective, tracing back other literary references, many cultures have identified figures expected to bridge the divine and the human—a fascinating echo with Plato’s notion of ‘the Ideal Form’ or even Prometheus among Greek contexts.

Each title emphasizes distinct characteristics of Jesus while weaving through historical threads, illuminating a tapestry of connection, commitment, and continuity in spirituality, a reminder of the ongoing quest for understanding throughout human experience.
