4 We have therefore resolved that in this coming month of October, in which the sacred devotions to Our Virgin Lady of the Rosary are solemnised throughout the Catholic world, all the devotions shall again be observed which were commanded by Us this time last year. - We therefore decree and make order that from the 1st of October to the 2nd of November following in all the parish churches [ curialibus templis ], in all public churches dedicated to the Mother of God, or in such as are appointed by the Ordinary, five decades at least of the Rosary be recited, together with the Litany. If in the morning, the Holy Sacrifice will take place during these prayers; if in the evening, the Blessed Sacrament will be exposed for the adoration of the faithful; after which those present will receivethe customary Benediction. We desire that, wherever it be lawful, the localconfraternity of the Rosary should make a solemn procession through the streetsas a public manifestation of religious devotion.
