 Two prominent Fort Worth-based Christian ministers led a delegation of Evangelical Christian leaders to Rome to meet privately with Pope Francis.

James and Betty Robison, co-hosts of the Life Today television program, and Kenneth Copeland, co-host of Believer's Voice of Victory, met the Roman Pontiff at the Vatican on Tuesday. The meeting lasted almost three hours and included a private luncheon with Pope Francis.

Mr. Robison told the Fort Worth Star Telegram, "This meeting was a miracle.... This is something God has done. God wants his arms around the world. And he wants Christians to put his arms around the world by working together."

Mr. Robison said he was impressed by Pope Francis' humility and courtesy to the visiting delegation of Evangelical Protestant Christian leaders.

In the spring of 1994, a distinguished group of Roman Catholics and evangelical Protestants issued a much-discussed statement, “Evangelicals and Catholics Together: The Christian Mission in the Third Millennium” (published in First Things Magazine, May 1994). That statement, commonly referred to as ECT, noted a growing “convergence and cooperation” between Evangelicals and Catholics in many public tasks, and affirmed agreement in basic articles of Christian faith while also underscoring the continuing existence of important differences. The signers promised to engage those differences in continuing conversations, and this has been done in meetings of noted theologians convened by Mr. Charles Colson and Father Richard John Neuhaus † (1936–2009) .
