has done, what God is doing, and what God will continue to do. It is refined in the Parable of The Publican (), "God, have mercy on me, a sinner", which shows more clearly its connection with the Jesus Prayer. In Western Christianity In Rome, the Liturgy was first celebrated in Greek. Josef Jungmann suggests the Kyrie in the Roman Mass is best seen as a vestige of a litany at the beginning of the Mass, like that of some Eastern churches, retained after Latin became normative. As early as the sixth century, Pope Gregory the Great noted that there were differences in the way in which eastern and western churches sang Kyrie. In the eastern churches all sing it at the same time, whereas in the western church the clergy sing it and the people respond. Also, the western church sang Christe eléison as many times as Kyrie eléison. In the Roman Rite liturgy, this variant, Christe, eléison, is a transliteration of Greek . "Kyrie, eléison" ("Lord, have mercy") may also be used as a response of the people to intentions mentioned in the Prayer of the Faithful. Since 1549, Anglicans have normally sung or said the Kyrie in English. In the 1552 Book of Common Prayer, the Kyrie was inserted into a recitation of the Ten Commandments. Modern revisions of the Prayer Book have restored the option of using the Kyrie without the Commandments. Other denominations, such as Lutheranism, also use "Kyrie, eléison" in their liturgies.

In the Paul VI Mass form, in the interests of brevity, each invocation is made only once by the celebrating priest, a deacon if present, or else by a cantor, with a single repetition, each time, by the congregation (though the Roman Missal allows for the Kyrie to be sung with more than six invocations, thus allowing the traditional use). Even if Mass is celebrated in the vernacular, the Kyrie may be in Greek. This prayer occurs directly following the Penitential Rite or is incorporated in that rite as one of the three
