The title His Holiness (and the associated form of address Your Holiness) is an official title or style referring to the pope; this use can be traced back several hundred years. It is also an official title for Oriental Orthodox patriarchs or Catholicoi. The title is also used by other religious leaders such as Lu Sheng-yen, the Dalai Lama, the Menri Trizin, and Da'i al-Mutlaq of the Dawoodi Bohras, etc.
His Holiness (Latin: Sanctitas) is the official style used to address the Roman Catholic pope.
The full papal title, rarely used, is:
The best-known title, that of "Pope", does not appear in the official list of titles, but is commonly used in the titles of documents and appears, in abbreviated form, in their signatures as "PP", standing for Papa (Pope). The 2020 Annuario Pontificio lists all of his formal titles, except Bishop of Rome, as "historical titles".
It is customary when referring to popes to translate the regnal name into local languages. Thus he is Papa Franciscus in Latin (the official language of the Holy See), Papa Francesco in Italian (the language of the Vatican), Papa Francisco in his native Spanish, and Pope Francis in English.
In February 2013, the Holy See announced that former Pope Benedict XVI would retain the style "His Holiness" after resigning and becoming pope emeritus.
The term is sometimes abbreviated as "HH" or "H.H." when confusion with "His/Her Highness" is unlikely.
His Holiness (Latin: Sanctitas) is the official style also used to address the Oriental Orthodox Catholicoi/patriarchs. In the Eastern Orthodox Church, the ecumenical patriarch of Constantinople has the title of His All Holiness (abbreviation HAH). It is also used for certain other Eastern patriarchs, notably those who head a church or rite which recognizes neither Rome's nor Constantinople's primacy.
The English-language honorific "His Holiness" and the female version "Her Holiness" have commonly been used for religious leaders from other traditions, including Buddhist leaders such as the Dalai Lama, the Gyalwa Karmapa, the Je Khenpo in Bhutan and Her Holiness Shinso Ito of the Shinnyo-en branch of Shingon Buddhism. In the Bön tradition it is used for the Menri Trizin. In Islam it is used in Ahmadiyya Sunni for the Caliph and in the Dawoodi Bohra sect of Ismaili Shia for the office of Da'i al-Mutlaq, Syedna.
