Pope John XXIII composed a prayer shortly after announcing his intention to call an ecumenical council. It has since been distributed throughout the world as anticipation builds for the Council, which we now know will open October 11, 1962. The following is an English translation.
O Divine Spirit, sent by the Father in the name of Jesus, Who dost infallibly assist and guide the Church, pour forth the fullness of thy gifts upon the Ecumenical Council.
Kind teacher and Comforter, enlighten the minds of our bishops, who, responding to the invitation of the Sovereign Roman Pontiff, will gather in solemn assembly.
Grant that from this Council there may come forth abundant fruits: that the light and strength of the Gospel may ever more widely influence human society: that new vigour may infuse the Catholic religion and its missionary task; that the Church’s teaching may be better known and Christian morality more widely practiced.
Sweet Guest of our souls, confirm our minds in truth, and dispose our hearts to obedience, so that the decisions of the council may find in us generous acceptance and prompt fulfillment.
We beseech Thee, too, on behalf of those sheep, who no longer belong to the one fold of Jesus Christ, that they also, glorifying as they do in the name of Christian, may finally regain unity under one Shepherd.
Renew in our time Thy wondrous works, as in a new Pentecost, and grant that Holy Church, gathered together in unanimous, more intense prayer, around Mary, the Mother of Jesus, and guided by Peter, may spread the kingdom of the Divine Saviour, which is the kingdom of truth, of justice, of love, and of peace. Amen.
