Thomas Roberts was closely associated with the Union de Priére, a group of Reformed ministers first touched by the Pentecostal movement in the South of France in the 1930s. The Union de Priére focused on prayer for four intentions: the revival of the churches by the conversion of souls; the salvation of the Jewish people; the visible unity of the body of Christ; and the Second Coming of Jesus Christ and the resurrection of the dead. ... Thomas Roberts grew in his grasp of the vision of one reunited body of Christ, manifesting the glory of the Savior and the power of the Spirit to the world ... Roberts was a model of a Christian who always remained faithful to his original call - he was always characteristically Pentecostal - yet who was so grateful to the Lord for opening his eyes to see the riches of other Christian traditions, Protestant, Catholic, and Orthodox.
