Christians affected by this new outpouring of the Holy Spirit quickly found themselves finding common ground crossing their theological differences and historically implied denominational animosities. The birth of ecumenical focus followed new streams of renewal and allowed many to encounter other Christians like never before, seeing what united them as grounds for continual dialogue, in though and life of the Church.
We do not look to the past with some kind of spiritual nostalgia but we move forward toward ever new encounters with Jesus. At the same time, we would like to acknowledge that past unprecedented events of historical and spiritual importance play crucial role in forming leaders of the next movements of God. As we make small steps toward ecumenical unity by meeting our fellow Christians and participating in the common times of prayer we strive for prudent discernment and renewed zeal in pursuing the heart of Jesus.
Between 1895-1903, Bl. Elena Guerra wrote 12 confidential letters to Pope Leo XIII, asking him to encourage greater devotion to the Holy Spirit among Catholics, urging him to "go ahead and open permanently in the Church the true home of prayer, a Cenacle [Upper Room], where the faithful united to the Divine Mother as she prayed with the Apostles in the Upper Room in Jerusalem, impetrino [third-person] from the Divine Spirit, with a Veni [coming] constant, the longed for renewal of the face of the earth." As a result, he wrote an encyclical on the Holy Spirit, Divinum Illud Munus, in 1897. He also sent a private letter to all bishops, recommending that the Novena for Pentecost be prayed at the dawn of the 20th century. At another request of Sr. Elena, Pope Leo XIII invoked the Holy Spirit by singing Veni Creator Spiritus in the name of the entire Church. On that same day, in Topeka, Kansas, a small church experienced an outpouring of the Holy Spirit which eventually gave birth to Pentecostalism and spread rapidly. Pope John XXIII asked that the Second Vatican Council (1962-1965) would be opened daily asking for a new Pentecost and his first beatification was of Elena Guerra. An outpouring of the Holy Spirit began to spread among Catholics in America at Duquesne University (Pittsburgh, PA) in 1967.
