聖良一世 （教宗、聖師）
聖人出生於意大利；在公元440年，登上伯多祿宗座，成為人靈的善牧和父親。當時教會面對內憂外患，聖人竭力維護信理的完整，及鞏固教會的統一。聖人闡明耶穌基督是兩性一位（真人真天主）的書函，在加采東大公會議（451年）中宣讀。當時出席的主教，聽了這封理論精確的書函，異口同聲歡呼：「伯多祿藉著良的口在講話」，並通過和宣布了「基督兩性一位」的信道。
聖人的講道和祈禱，對羅馬禮儀的發展，有很大的影響，尤以闡釋聖子降生奧蹟的真諦，最為人稱頌。
他對蠻人的侵襲，或竭力抗拒，或予以安撫，剛柔並重，救羅馬於水火。當敵兵退走後，聖人又立即致力救濟災民，恢復秩序，又派司鐸前往非洲，為俘虜服務。
聖人凡事依靠天主，處事公正賢明。無論富人窮人、神職教友、羅馬人和外國人，都對他敬愛有加。聖人於461年安逝。
聖人與聖額我略一世，及聖尼各老一世，同稱為「偉大」的教宗。
集禱經
天主，你把教會建立在宗徒的磐石上；你絕不容許陰間的門戰勝她。求你因教宗聖良一世的代禱，使教會堅守真理，永享平安。因你的聖子、我們的主耶穌基督，他和你及聖神，是唯一天主，永生永王。亞孟。
Saint Leo the Great, Pope and Doctor of the Church
St. Leo the Great, elected in 440 as Pope, worked tirelessly as “Peter’s successor,” guiding his fellow bishops as “equals in the episcopacy and infirmities.”
St. Leo’s work branched into areas indicative of his notion of the pope’s total responsibility for the flock of Christ. He worked at length to control the heresies of Pelagianism—overemphasizing human freedom—Manichaeism—seeing everything material as evil—and others, placing demands on their followers so as to secure true Christian beliefs.
During the pontificate of St. Leo I (d. 461), the Ecumenical Council of Chalcedon defined Jesus Christ as one divine Person with two natures: divine and human. St. Leo has written Epistola Dogmatica (the “Tome” of Leo) to Patriarch Flavian of Constantinople, which was read and assented to by the Council Fathers.
With strong faith, St. Leo also led the defense of Rome against barbarian attack, taking the role of peacemaker.
St. Leo died on November 10, 461. Pope Benedict XIV proclaimed him Doctor of the Church in 1754.
Collect
O God, who never allow the gates of hell
to prevail against your Church,
firmly founded on the apostolic rock,
grant her, we pray,
that through the intercession of Pope Saint Leo,
she may stand firm in your truth
and know the protection of lasting peace.
Through our Lord Jesus Christ, your Son,
who lives and reigns with you in the unity of the Holy Spirit,
one God, for ever and ever. Amen.
