The Pope spoke on Jan. 7 after a meeting with a delegation of the alliance led by its president, the Rev. Clifton Kirkpatrick, stated clerk of the Presbyterian Church (USA).

"I pray that our meeting today will itself bear fruit in a renewed commitment to work for the unity of all Christians," said Benedict, who said after his election in April that promoting Christian unity would be his "primary task."

WARC has more than 200 Congregational, Presbyterian, Reformed and United churches that trace their origins to the Reformation.

Kirkpatrick said after his meeting with the Pope that he hopes recent steps toward unity are the first of many.

"There is still much to be done to move beyond our past condemnations of one another, to truly respect one another as parts of the one body of Jesus Christ, serve God together without worrying about inhibitions in our nations and to come together at the table of our Lord," he said.

Kirkpatrick also urged joint action on social-justice issues.

"We are eager ... to pursue with you how Catholic and Reformed Christians might be partners together for God's justice in a world wracked by poverty, war, ecological destruction, and the denial of human freedom," he said.

Pope Benedict hailed the Catholic-Reformed dialogue, saying that it has "made an important contribution to the demanding work of theological reflection and historical investigation indispensable for surmounting the tragic divisions which arose among Christians in the sixteenth century."

The Pope also spoke of a need for "a purification of memory," noting that his predecessor, Pope John Paul II, was a pioneer in this endeavor.

"I am pleased to learn that several of the Reformed Churches ... have undertaken similar initiatives," he said.

After the meeting, WARC's general secretary, the Rev. Setri Nyomi, said: "This visit was an important symbol of WARC's commitment to Christian unity as well as to working with other Christian world communions in transforming the world into more just communities."

The full text of Kirkpatrick's message to Benedict, dated Jan. 7:

Your Holiness, in this Season of Epiphany we greet you in the name of Jesus Christ, who is revealed as Lord and Savior of the world. We extend a special word of congratulations to you as you begin your ministry as the Successor to Peter and assure you of the prayers of Reformed Christians all over the world that God will richly bless your ministry.

We come representing the World Alliance of Reformed Churches, the global fellowship of 215 churches of Reformed and Congregational traditions composed of some 75 million Christians from all parts of our world. We are churches shaped by the Protestant Reformation and its values but also deeply committee to the one, holy, catholic and apostolic church of which both of our communities are a part.

We are extremely grateful for the three phases of the Reformed-Roman Catholic dialogue that have been completed and have born real fruit in our common understanding of the presence of Christ and the nature of the church and in our common witness to the Kingdom of God. We are eager to begin the next stage of efforts to move closer together in common faith and witness and look forward to exploring this possibility with the Pontifical Council for Promoting Christian Unity while we are here in Rome. As Reformed Christians, we will also soon be commemorating the 500th anniversary of the founding of our movement and are eager to find ways to approach these events and our learning from them ecumenically with our sisters and brothers from the Catholic Church.
