130 We most humbly pour forth Our earnest prayer at the Throne of His Grace, that God, the Author of all graces, the inspirer of all good desires and deeds, may bring this about, and deign to give it bountifully according to the greatness of His liberality and omnipotence, and as a token of the abundant blessing of the same Omnipotent God, We most lovingly grant to you, Venerable Brethren, and to the clergy and people committed to your watchful care, the Apostolic Benediction. Given at Rome, in Saint Peter's, this 31st day of December, of the year 1930, the ninth of Our Pontificate.
