how might a community discern if its unity truly reflects the divine, as jesus prays for?

Adds the setting and its conversation across both testaments.

John 17:21

“that they may all be one; even as you, Father, are in me, and I in you, that they also may be one in us; that the world may believe that you sent me.”

This verse is part of Jesus' 'High Priestly Prayer' recorded in John's Gospel, offered shortly before his crucifixion. He is praying for his disciples and all future believers, entrusting them to God and expressing his deepest desires for their unity and mission in the world.

What aspects of our community life genuinely invite the world to believe in something beyond ourselves?

Then — the setting

This prayer from Jesus comes from the Gospel of John, likely written in the late 1st century CE, possibly in Ephesus. The audience would have been early Christian communities, grappling with their identity in a diverse Greco-Roman world, facing internal disputes and external pressures. The concept of unity (Greek: *henotes*) was important in both Jewish thought (monotheism, the unity of Israel) and some Hellenistic philosophies (the 'one' behind all things), but Jesus' prayer connects it specifically to the relational unity within the Godhead, and as a witness to the world.

Across the Testaments

The Old Testament consistently emphasizes the singularity and unity of God (Deuteronomy 6:4, 'Hear, O Israel: Yahweh is our God; Yahweh is one'). It also stresses the unity of the people of Israel as God's chosen community. Jesus' prayer in the New Testament takes this concept further by linking the unity of believers directly to the relational unity of the Father and Son, presenting it not just as a sociological ideal but as a theological reflection of God's own nature. This unity is now extended to a new, diverse community beyond ethnic Israel, meant to serve as a witness to the world.
