Continuing the work of the First Vatican Council, St. John XXIII opened the Second Vatican Council with a beautiful prayer on October 11, 1962.
The prayer puts all trust in God, asking him to watch over all the bishops of the Church who would convene in Rome.
Almighty God, we have no confidence in our own strength; all our trust is in you. Graciously look down on these Pastors of your Church. Aid their counsels and their legislation with the light of your divine grace. Be pleased to hear the prayers we offer you, united in faith, in voice, in mind.
Mary, help of Christians, help of bishops; recently in your church at Loreto, where We venerated the mystery of the Incarnation, you gave us a special token of your love. Prosper now this work of ours, and by your kindly aid bring it to a happy, successful conclusion. And do you, with St. Joseph your spouse, the holy apostles Peter and Paul, St. John the Baptist and St. John the Evangelist, intercede for us before the throne of God.
To Jesus Christ, our most loving Redeemer, the immortal King of all peoples and all ages, be love, power and glory for ever and ever. Amen.
