In the celebration of the Mass, the critical role of God's mercy frequently comes to the fore. As imperfect human beings, we encounter in the Mass God's merciful offer to raise us up and to give us hope and strength despite our weaknesses. To assist delving deeper into the content of the Mass itself, there follows a concise list of moments in the Order of Mass when the mercy of God is explicitly acknowledged or sought. Those who preach on the theme of mercy might wish to draw their hearers' attention to some of these passages, both to help strengthen their appreciation for God's mercy and to help pray the Mass with greater devotion.
In addition to the texts from the Order of the Mass, there are innumerable references to God's mercy which are encountered both in the proper prayer texts for the various Masses, as well as in the Scripture passages proclaimed in the Liturgy of the Word. Furthermore, there are numerous other moments in the Mass when mercy is sought, even if not mentioned explicitly by name. For example, the silent prayer of the deacon or priest who has just read the Gospel is clearly reliant on God's mercy: "Through the words of the Gospel, may our sins be wiped away". Whether or not the very word is used, God's mercy is truly never far from the many liturgical elements of the Mass. Mass texts are from the Roman Missal, Third Edition.
