About Us


Grounded in our faith in Jesus Christ and in the teachings of the Second Vatican Council’s Decree on Ecumenism and Declaration on Non-Christian Religions, the Office for Ecumenical and Interreligious Affairs seeks to foster Christian unity and to deepen our relationships with Jews, Muslims, Buddhists and followers of other religions through initiatives that resonate on a local and global scale.

Integral to our Catholic identity, and as a path to evangelization most recently articulated in Pope Francis’ Evangelii Gaudium, we support Cardinal Cupich in his ecumenical and interreligious ministry, seeking to nurture understanding and respect among all religious groups through dialogue, formation, prayer, and collaboration in civic affairs that promote the common good. We also offer resources for educational and pastoral support, and provide expert consultations for parishes, schools and other agencies within the Archdiocese of Chicago.

The restoration of unity among all Christians is one of the principal concerns of the Second Vatican Council. Christ the Lord founded one Church and one Church only. However, many Christian communions present themselves … as the true inheritors of Jesus Christ … Such division openly contradicts the will of Christ, scandalizes the world, and damages the holy cause of preaching the Gospel to every creature.
– Second Vatican Council, Unitatis Redintegratio, 1

The Catholic Church rejects nothing that is true and holy in other religions and has a high regard for the manner of life and conduct, the precepts and doctrines, which, although differing in many ways from her own teaching, nevertheless often reflect a ray of that truth which enlightens all people.
– Second Vatican Council, Nostra Aetate, 2
