23 But that that may happily take place, We beg and implore the full grace of God and motherly aid of the Immaculate Virgin. As a foretaste of heavenly gifts and witness of Our fatherly good will towards you, Venerable Brethren, your clergy, and all your people, We lovingly impart the apostolic blessing. Given at St. Peter's, in Rome, the fifth day of May, 1888, the eleventh of Our pontificate.
