Jn 17:15 — I do not ask that you take them out of the world

The prayer concludes with a vision of eternal communion and divine love at work in the world through believers.

Church Teaching on This Passage

The Fathers and the Magisterium read John 17 as a foundational text on the Church’s identity and mission. The Church Fathers emphasize the unity and love expressed in Jesus interceding for the disciples and all believers. Augustine, Chrysostom, and Origen reflect on the High Priestly Prayer as a model of Christ’s ongoing mediation, which the Church continues through prayer and sacramental life. In the modern Magisterium, this passage is cited in discussions of ecclesial unity, mission to the world, and the Holy Spirit as the agent who sustains believers in truth. The Catechism of the Catholic Church (CCC 824-830, and related passages) underscores that the Church is one, holy, catholic, and apostolic, with unity grounded in Christ and animated by the Spirit, as foreshadowed in this prayer.
