How to Celebrate “Divine Mercy Sunday”
In May 5, 2000 the Decree of the Congregation for Divine Worship and the Discipline of the Sacraments added a new title to the Second Sunday of Easter. In the new Missale Romanum it is now officially referred to as"DOMINICA II PASCHÆ seu de divina Misericordia," or “The Second Sunday of Easter that is Divine Mercy Sunday.”
The celebration of Divine Mercy Sunday is essentially the celebration of the liturgy of the Second Sunday of Easter. It should be noted that thescriptural readings and liturgical prayers in all the three cyclesare centred on the forgiveness and infinite mercy of God. This is the focus of the homily.
In a second Decree, dated August 3, 2002, the Apostolic Penitentiary announced that in order "to ensure that the faithful would observe this day with intense devotion, the Supreme Pontiff himself established that this Sunday be enriched by a plenary indulgence…so that the faithful might receive in great abundance the gift of the consolation of the Holy Spirit. In this way, they can foster a growing love for God and for their neighbor, and after they have obtained God's pardon, they in turn might show a prompt pardon to their brothers and sisters."
Thus, to fittingly observe the Feast of Mercy, we should:
1. Celebrate the Feast on the Second Sunday of Easter.
During the Mass of canonization of St. Faustina on April 30, 2000, Pope John Paul II proclaimed: "It is important then that we accept the whole message that comes to us from the word of God on this Second Sunday of Easter, which from now on throughout the Church, will be called Divine Mercy Sunday."
2. Sincerely repent of all our sins, go to Confession (preferably beforehand), and receive Holy Communion on the day of the Feast.
According to St. Faustina, Our Lord promises the remission of guilt and the punishment of sins, for those who go to confession and receive communion on this day.
“On that day the very depths of My tender mercy are open. I pour out a whole ocean of graces upon those souls who approach the fount of My mercy. The soul that will go to Confession and receive Holy Communion shall obtain complete forgiveness of sins and punishment. On that day all the divine floodgates through which grace flow are opened. Let no soul fear to draw near to Me, even though its sins be as scarlet. My mercy is so great that no mind, be it of man or of angel, will be able to fathom it throughout all eternity.” (Diary of Sr. Faustina, 699)
Many take this to mean that they must go to Confession ON Divine Mercy Sunday. This is not true. To receive the benefits of the Promise one must be in the state of grace. The Lord does not promise the absolution of grave sin on Divine Mercy Sunday, but points us to the Sacrament of Penance. To receive the grace we should be disposed and this is done by a confession near the time of Mercy Sunday. According to the Cardinal of Krakow, the confession which a Catholic makes during Lent in preparation for Easter is sufficient. It would be impossible for priests to hear everyone's Confession on the feast itself. Instead priority should be given to those who have not yet gone to Confession.
The plenary indulgence is granted to the faithful who take part in the prayers and devotions held on Divine Mercy Sunday, or who, in the presence of the Blessed Sacrament exposed or reserved in the tabernacle, recite the Our Father and the Creed, adding a devout prayer to the merciful Lord Jesus, eg. “Merciful Jesus, I trust in you!” The usual conditions apply, namely one is to have made asacramental confession up to about 20 daysbefore or after Divine Mercy Sunday, have received Eucharistic communion and prayed for the intentions of the Holy Father.
3. Venerate the Imageof The Divine Mercy;
Pope John Paul II said that the image of The Divine Mercy portrays the Risen Jesus Christ bringing Mercy to the whole world. Our Lord said “I want the image to be solemnly blessed on the first Sunday after Easter, and I want it to be venerated publicly so that every soul may know about it”. (Diary 341) “I promise that the soul that will venerate this image will not perish”. (Diary 48) "I am offering people a vessel with which they are to keep coming for graces to the fountain of mercy. That vessel is this image with the signature: Jesus, I trust in You”. (Diary 327)
A previously blessed image can be used in processions, be the object of veneration during a communal recitation of the Chaplet of Mercy or other devotions as the parish may celebrate during the Feast of Mercy.
4. Be merciful to others, through our actions, words, and prayers on their behalf.
In effect, the celebration of Divine Mercy Sunday is simple. In fact, outside of having an image of The Divine Mercy in the church to venerate, there really is nothing else to do. It is Jesus Himself that does all the work on that day. All that we need to do is to tell everyone about God’s Mercy and urge those who haven't made Confession yet, to do so. Easter Sunday is the best time for us to talk about Mercy.

如何慶祝「救主慈悲主日」
2000年5月5日，教廷禮儀及聖事部(Congregation for Divine Worship and the Discipline of the Sacraments)為復活期第二主日增添了新的名號。在新編《羅馬彌撒經書》中，該主日現在已正式定為「復活期第二主日又名救主慈悲主日」(DOMINICA II PASCHAE seu de divina Misericordia)。
慶祝救主慈悲主日實質上就是慶祝復活期第二主日的禮儀。應該注意的是在三個禮儀年的指定讀經和禮儀禱文中，都以寬恕和天主無限慈悲為主題，這也就是講道的重點。
教宗經宗座聖赦院於２００２年８月３日發出第二項法令，宣佈「為使所有信友以熱切敬禮慶祝這日子，教宗為救主慈悲主日頒賜全大赦給教友‧‧‧‧‧‧為使信友極豐裕地獲得聖神安慰的恩寵。這樣，信友能培養出對天主和近人的愛，並在得到天主的寬恕後，也能同樣即時寬恕他們的兄弟姊妹」。
因此，如要相稱地慶祝慈悲主日，我們應該要：
(１) 在復活期第二主日慶祝救主慈悲主日
２０００年４月３０日，教宗若望保祿二世在傅天娜修女宣聖的感恩祭中講道時說：「我們接受在復活期第二主日天主聖言給我們的整個訊息是尤其重要，從今以後，這個主日在整個教會內，將被稱為「救主慈悲主日」。」
為敬禮救主慈悲主日，很多堂區現在也在慶日當天下午舉行特別的彌撒；不過，這樣做不是必要的，並不是每一個堂區都能編排出時間舉行額外一台彌撒。要明白救主慈悲慶日和復活期第二主日皆是同一慶典，該主日所有的彌撒（包括星期六晚的提前彌撒）也是懷著同一的主題；因此，救主慈悲訊息為該主日講道的重點就最適合不過了。
(２) 誠懇地痛悔己罪，辦告解（最好在領聖體前），和在慶日當天領聖體
根據聖傅天娜所說，耶穌許諾在當天，已辦妥當告解和領聖體的信友會獲得罪過和罪罰的全赦。
「在 這天，我會向眾人大開我慈悲的深淵，並向所有投奔我慈悲泉源的人靈，傾瀉海洋般大量的恩寵。已辦妥當告解和領聖體的靈魂會獲得罪過和罪罰的全赦。當天所有 天恩的水閘也要開放。但願沒有靈魂害怕到我跟前來，即使他們的罪紅得發紫。我的慈悲是多麼偉大，任何人或天使，縱使用盡心思，永遠也不能完全了解的。」（傅天娜修女靈修日記699）
有 很多人以為他們一定要在救主慈悲主日當天辦告解，但不是一定的，我們要獲得天主承諾的神益，靈魂必須在恩寵的狀態中，主不是答應我們在救主慈悲主日當天赦 免大罪，卻指示我們使用悔罪聖事。要得到恩寵，我們一定要使自己在合適的狀態，就是在接近救主慈悲主日的期間辦妥了告解。
據克拉科夫的樞機所說，天主教徒在四旬期為準備復活節而辦的告解已足夠了。司鐸不可能在慶日裡聆聽每個人辦告解，反而為那些在四旬期內未辦告解的教友，在當天應優先給予他們機會去辦告解。
要獲得全大赦，信友在救主慈悲主日須參與救主慈悲祈禱和敬禮，或在聖體前（明供或貯存在聖體櫃內），誦念天主經和信經，並加上一篇敬禮慈悲耶穌的禱文（例如：「慈悲耶穌，我信賴祢！」亦須符合慣常的條件，就是在救主慈悲主日，或之前或之後的二十天內辦告解，善領聖體聖事，和為教宗意向祈禱。
(３) 恭敬救主慈悲聖像畫
教宗若望保祿二世曾說過，救主慈悲聖像畫描繪出已復活的耶穌將祂的慈悲帶給全世界。主耶穌說：「我希望救主慈悲聖像畫在救主慈悲主日隆重地受祝聖，並公開給群眾敬禮，使每個人靈都認識它。」（日記341）「我許下凡恭敬聖像畫的人不會喪亡。」（日記48）「我賜給世人一個器皿，他們可藉此常常來到慈悲的泉源獲取恩寵。這器皿就是這幅簽署著「耶穌，我信賴祢！」的聖像畫。」（日記327）
已被祝聖的聖像畫，在堂區慶祝慈悲曕禮時，可用於出遊、公禱誦念慈悲串經或其他敬禮。
(４)慈悲待人──藉著我們的行為、言語和祈禱
耶穌告訴傅天娜修女說：「我要求妳基於愛我的緣故，實施仁慈的行為。妳應該時時處處仁慈地對待近人……我要教妳三個仁慈地對待近人的方法：第一是行為，第二是言語，第三是祈禱。這三種方法充份地表達了仁慈，而且還無容置疑地證明妳對我的愛。人靈能藉著這三種行為，光榮和恭敬我的慈悲。」（日記742）
根據第二次頒佈的法令，司鐸要温和地鼓勵信友盡力時常實踐愛德和慈悲，跟隨基督的榜樣，因為祂說：「憐憫人的人是有福的，因為他們要受憐憫。」（瑪５：７）
為慶祝這瞻禮，應實踐慈悲，即以行為、言語和祈禱來善待別人。事實上，要我們如耶穌一般慈悲就是慶祝救主慈悲慶日的所有原因了──天主藉著我們彰顯祂的慈悲。
慶祝救主慈悲主日實際上是簡單的。除了在聖堂內恭敬救主慈悲聖像畫之外，便沒有什麼事需要做了，其實是耶穌自己做當天所有的工作。我們要做的只是向人講論天主的慈悲和催促那些尚未辦告解的人去辦告解。復活主日就是最佳的時候談論慈悲了。
