WPCU 2020 imageUSCCB Celebrates the Week of Prayer for Christian Unity 2020

The Week of Prayer for Christian Unity is celebrated annually all around the world. In the northern hemisphere, it is celebrated January 18-25. The celebration has a history of over 100 years. By annually observing the WPCU, Christians move toward the fulfillment of Jesus' prayer at the Last Supper "that they all may be one."  (cf. John 17:21)

Every year, in preparation for the WPCU, ecumenical partners in a particular region were asked to prepare a basic text on a biblical theme. This year, the theme from Malta is "They Showed Us Unusual Kindness." (cf. Acts 28:2)

At the U.S. Conference of Catholic Bishops, staff took part in an ecumenical prayer service on the morning of Tuesday, January 21, 2020, presided over by Msgr. Jeffrey Burrill, Associate General Secretary. Staff of the secretariat are also available all week during lunch hours to raise awareness for Christian unity.

Welcome from the Executive Director

Dialogue: What we do

"Dialogue is our method, not as a shrewd strategy but out of fidelity to the One who never wearies of visiting the marketplace, even at the eleventh hour, to propose his offer of love (Mt 20:1-16). The path ahead, then, is dialogue among yourselves, dialogue in your presbyterates, dialogue with lay persons, dialogue with families, dialogue with society. I cannot ever tire of encouraging you to dialogue fearlessly."
- Pope Francis, Address to the U.S. Bishops, September 23, 2015

"I cannot ever tire of encouraging you to dialogue fearlessly." - Pope Francis

“Dialogue” first entered the Church’s vocabulary as the method of approaching the modern world Pope Saint Paul VI promoted. This illustrates the spirit of the Second Vatican Council, which produced Unitatis Redintegratio and Nostra Aetate, the foundational documents that guide the Church’s relations with other Christian bodies and religious communities. Thus, the Church committed itself irrevocably to building fruitful relationships with others: fostering bonds of friendship, mutual understanding, and constructive collaboration.

The bishops of the United States established the Committee for Ecumenical and Interreligious Affairs (BCEIA) as part of this endeavor. It sponsors a number of dialogues with other Christian communities and members of other religions in the United States or North America. In most cases, these dialogues parallel those that the Holy See sponsors at the universal level.

Each dialogue has its own scope, method, and aim. We invite you to use this website as a resource in exploring the complexities of the Church’s dialogues in the United States. Here, you will find pastoral, academic, and historical resources to help all grow in understanding and appreciation.
