Quick answer
Jesus prays that all believers may be one, modeled on the union of Father and Son, so that the world may believe the Father sent him. Christian unity bears witness to Christ.
Overview
The unity Jesus seeks is grounded in and patterned after the oneness of Father and Son, and it is a unity 'in us,' rooted in fellowship with God. Such genuine unity among believers serves an evangelistic purpose: it testifies to the world that Jesus is sent from God. Christians have understood this both as spiritual unity in truth and love, and as a call to visible, loving fellowship.

How traditions read this
Faithful ways Christians have pictured the one God in three persons.
The Western/Augustinian approach begins from the one divine essence: God is one being subsisting in three persons, distinguished only by their relations of origin (begetting, proceeding).
Key points · Unity of essence first; persons as subsisting relations; the analogy of mind, knowledge, love.
Augustine; Thomas Aquinas
This emphasis starts from the three persons as a communion of love — "that they may be one, even as we are one" — and sees the Trinity as the pattern of perfect relationship.
Key points · The mutual indwelling (perichoresis); love between the persons; relational personhood.
drawn from the Cappadocians
The Eastern emphasis: the Father is the single source (monarchia) of the Son (eternally begotten) and the Spirit (eternally proceeding), grounding the unity of God in the person of the Father.
Key points · The Father as fountain of deity; the Son begotten, the Spirit proceeding; one source, not three.
the Cappadocian Fathers
Each view is stated as that tradition would put it, with representative sources. Limitless Word presents them side by side and endorses none — see the methodology.
