Penance in the context of "Good works"

In the history of the Catholic Church, a crusade indulgence was any indulgence—remission from the penalties imposed by penance—granted to a person who participated in an ecclesiastically sanctioned crusade. It had its origins in the Council of Clermont that closed on 27 November 1095. According to Lambert of Arras, who was present, the council decreed that, "Whoever for devotion alone, not to gain honour or money, goes to Jerusalem to liberate the Church of God can substitute this journey for all penance." This marked the start of the First Crusade. Later popes and councils often invoked "the same remission as instituted by Pope Urban at the council at Clermont." The connection to the liberation of Jerusalem was later weakened and the same or similar indulgence offered to participants in the Northern Crusades and the Albigensian Crusade.

Easter, also called Pasch (/pæsk/) or Pascha (Aramaic: פַּסְחָא , paskha; Greek: πάσχα, páskha) or Resurrection Sunday, is a Christian festival and cultural holiday commemorating the resurrection of Jesus from the dead, described in the New Testament as having occurred on the third day of his burial following his crucifixion by the Romans at Calvary c. 30 AD. It is the culmination of the Passion of Jesus, preceded by Lent (or Great Lent), a 40-day period of fasting, prayer, and penance.

Easter-observing Christians commonly refer to the last week of Lent, before Easter, as Holy Week, which in Western Christianity begins on Palm Sunday (marking the entrance of Jesus in Jerusalem), includes Spy Wednesday (on which the betrayal of Jesus is mourned), and contains the days of the Easter Triduum including Maundy Thursday, commemorating the Maundy and Last Supper, as well as Good Friday, commemorating the crucifixion and death of Jesus. In Eastern Christianity, the same events are commemorated with the names of days all starting with "Holy" or "Holy and Great", and Easter itself might be called Great and Holy Pascha. In both Western and Eastern Christianity, Eastertide—also known as the Easter or Paschal season—begins on Easter Sunday and continues for seven weeks, concluding on the 50th day, Pentecost Sunday. However, in Eastern Christianity, the leavetaking of the feast occurs on the 39th day, the eve of the Feast of the Ascension.

Repentance (a term related to Greek: μετάνοια, romanized: metanoia), in Christianity, refers to being sorrowful for having committed sin and then turning away from sin toward a life of holiness.

In certain Christian traditions, such as Catholic theology, Lutheran theology, Orthodox theology and Anglican theology, repentance plays a key role in confession and absolution. It can specifically refer to a stage in Christian salvation in which an individual gains awareness of God's standard, acknowledges their past or present wrongdoings, and deliberately turns away from sin toward God; its numeration as a stage in the ordo salutis varies with the Christian denomination, with the Reformed theological tradition arguing it occurs after faith. Christian denominations that adhere to the liturgical kalendar, such as Catholicism, Lutheranism, Moravianism and Anglicanism, focus on repentance during the season of Lent, while emphasizing its importance in the life of the believer throughout the year.

Absolution is a theological term for the forgiveness imparted by ordained Christian priests and experienced by Christian penitents. It is a universal feature of the historic churches of Christendom, although the theology and the practice of absolution vary between Christian denominations.

Some Christian traditions see absolution as a sacrament—the Sacrament of Penance. This concept is found in the Catholic Church, Eastern Orthodox Church, Oriental Orthodox Churches, Assyrian Church of the East and the Lutheran Church. In other traditions, including the Anglican Communion and Methodism, absolution is seen as part of the life of the church, with the Thirty-nine Articles and Twenty-five Articles respectively counting absolution amongst the five rites described as "Commonly called Sacraments, but not to be counted for Sacraments of the Gospel". Confession and Absolution is practiced in the Irvingian Churches, though it is not a sacrament.

Confession, in many religions, is the acknowledgment of sinful thoughts and actions. This is performed directly to a deity or to fellow people.

It is often seen as a required action of repentance and a necessary precursor to penance and atonement. It often leads to reconciliation and forgiveness.

A Holy Week procession is a public ritual march of clergy and penitents which takes place during Holy Week in Christian countries, especially those with a Catholic culture. Various images of the saints, especially the Virgin Mary, and most importantly the image of the crucified Christ are carried aloft by foot on shoulder-borne pasos (or on wheeled carrozas in the Philippines) as an act of penance; acts of mortification are carried out; traditional Christian hymns and chants are sung (except during the silent processions of Good Friday). In many confraternities of penitents, the faces of the members are covered by elaborate hoods, such as the capirote, as a way of hiding one's identity in order to not ostentatiously draw attention to oneself while performing penance. Crosses, and biers holding Catholic holy images surrounded with flowers and offerings of candles, are carried usually from one parish church to another led by the clergy, monastic orders, or heads of the penitential orders.

Self-flagellation is the disciplinary and devotional practice of flogging oneself with whips or other instruments that inflict pain. In Christianity, self-flagellation is practiced in the context of the doctrine of the mortification of the flesh and is seen as a spiritual discipline. It is often used as a form of penance and is intended to allow the flagellant to share in the sufferings of Jesus, bringing their focus to God.

The main religions that practice self-flagellation include some branches of Christianity and Islam. The ritual has also been practiced among members of several Egyptian and Greco-Roman cults.
