Octobri mense

Octobri mense is the fifth of twelve encyclicals written by Leo XIII on the Rosary. Starting in 1883, all but two were issued in September in anticipation of October, the month dedicated to the Rosary. The subject of Octobri mense was the power of prayer and the efficacy of the rosary.{{Cite web |url=http://campus.udayton.edu/mary/rosarymarkings29.html |title=Thompson, Thomas.

"It is indeed a cause of great sorrow that so many should be deterred and led astray by error and enmity to God; that so many should be indifferent to all forms of religion, and should finally become estranged from faith; that so many Catholics should be such in name only, and should pay to religion no honour or worship."[https://www.vatican.va/holy_father/leo_xiii/encyclicals/documents/hf_l-xiii_enc_22091891_octobri-mense_en.html Pope Leo XIII, Octobri mense, §2, Vatican, September 22, 1891] Invoking Mary under the title Helper of Christians, Leo urges the faithful to have recourse to her.

"The Eternal Son of God [...] did not accomplish His design without adding there the free consent of the elect Mother, who represented in some sort all human kind, according to the illustrious and just opinion of St. Thomas, who says that the Annunciation was effected with the consent of the Virgin standing in the place of humanity."{{sfn|Octobri mense, §4}}

St. Dominic’s devotion to the rosary is noted:

"the devotion was begun and spread abroad by the holy Patriarch Dominic as a most potent weapon against the enemies of the faith at an epoch not, indeed, unlike our own, of great danger to our holy religion. The heresy of the Albigenses had ...overrun many countries, and this most vile off spring of the Manicheans [...] There seemed to be no human hope of opposing this fanatical and most pernicious sect when timely succor came from on high through the instrument of Mary's Rosary. Thus under the favor of the powerful Virgin, the glorious vanquisher of all heresies"{{Cite web|url=https://www.vatican.va/content/leo-xiii/en/encyclicals/documents/hf_l-xiii_enc_22091891_octobri-mense.html|title=Octobri Mense, para. 8|last=|first=|date=|website=|archive-url=|archive-date=|access-date=}}

In every September for the next seven years following the writing of Octobri Mense in September 1891, Pope Leo XIII dedicated the month of October to the Rosary through the authorship of an encyclical.

These encyclicals continued the use of the Rosary by Leo as a rallying point against the evils in 1892,{{Cite web|url=https://www.vatican.va/content/leo-xiii/en/encyclicals/documents/hf_l-xiii_enc_08091892_magnae-dei-matris.html|title=Magnae Dei Matris|last=|first=|date=|website=|archive-url=|archive-date=|access-date=}} 1893{{Cite web|url=https://www.vatican.va/content/leo-xiii/en/encyclicals/documents/hf_l-xiii_enc_08091893_laetitiae-sanctae.html|title=Laetitiae Sanctae|last=|first=|date=|website=|archive-url=|archive-date=|access-date=}} and 1894.{{Cite web|url=https://www.vatican.va/content/leo-xiii/en/encyclicals/documents/hf_l-xiii_enc_08091894_iucunda-semper-expectatione.html|title=Iucunda Semper Expectatione|last=|first=|date=|website=|archive-url=|archive-date=|access-date=}}
