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.

It's always enlightening to explore the titles ascribed to Jesus because each reflects deep theological implications and biblical narratives. The New Testament is ripe with phrases celebrating Jesus’ diverse roles—from 'Immanuel,' meaning 'God with us,' to 'Light of the World', which gives a nod to spiritual enlightenment.

Interestingly, 'Holy One of Israel' stands apart in biblical context—it's strictly linked to God Almighty. Throughout the scriptures, this title echoes throughout the Old Testament, often in relationship to Israel itself. For instance, it’s used liberally in books like Isaiah—emphasizing God’s covenant relationship with His people and often highlighting His divine characteristics: holiness and power.

The use of specific titles not only helps define the attributes of Jesus but also subtly reinforces the distinctiveness of the creator and the creation. Moreover, Old Testament references offer fascinating insights into how Jesus' followers interpreted and understood him through their sacred tradition.

For trivia lovers, let’s not forget that Isaiah 9:6 refers to a 'Wonderful Counselor,' 'Mighty God,' 'Everlasting Father,' and 'Prince of Peace.' This rich array of titles not only anticipates Jesus' naissance but encapsulates a powerful yearning for hope, peace, and divine guidance within a tumultuous world. It’s the strings of this rich narrative tapestry that harmonies beautifully with both the Old and New Testament discussions. Isn’t it amazing how intricately woven these stories and titles are?
