Calvary in the context of "Church of the Holy Sepulchre"

In Christianity, Jesus is the Son of God as chronicled in the Bible's New Testament, as well as prophesied in the Old Testament, and is held to be God the Son, a prosopon (Person) of the Trinity of God. Christians believe him to be the Jewish messiah (giving him the title Christ), who was prophesied in the Bible's Old Testament. Through Jesus's crucifixion and resurrection, Christians believe that God offers humans salvation and eternal life, with Jesus's death atoning for all sin.

These teachings emphasize that as the Lamb of God, Jesus chose to suffer nailed to the cross at Calvary as a sign of his obedience to the will of God, as an "agent and servant of God". Jesus's choice positions him as a man of obedience, in contrast to Adam's disobedience. According to the New Testament, after God raised him from the dead, Jesus ascended to heaven to sit at the right hand of God the Father, with his followers awaiting his return to Earth and God's subsequent Last Judgement.

Lamb of God (Greek: Ἀμνὸς τοῦ Θεοῦ, romanized: Amnòs toû Theoû; Latin: Agnus Dei, Ecclesiastical Latin: [ˈaɲ.ɲus ˈde.i]) is a title for Jesus that appears in the Gospel of John. It appears at John 1:29, where John the Baptist sees Jesus and exclaims, "Behold the Lamb of God who takes away the sin of the world." It appears again in John 1:36.

Christian doctrine holds that a divine Jesus chose to suffer crucifixion at Calvary to save the world from its sins. He was given up by divine Father, as an "agent and servant of God" in carrying away the sins of the world. In Christian theology the Lamb of God is viewed as both foundational and integral to the message of Christianity.

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.

The Mass is the central liturgical service of the Eucharist in the Catholic Church, in which bread and wine are consecrated and become the body and blood of Christ. As defined by the Church at the Council of Trent, in the Mass "the same Christ who offered himself once in a bloody manner on the altar of the cross, is present and offered in an unbloody manner". The Church describes the Mass as the "source and summit of the Christian life", and teaches that the Mass is a sacrifice, in which the sacramental bread and wine, through consecration by an ordained priest, become the sacrificial body, blood, soul, and divinity of Christ as the sacrifice on Calvary made truly present once again on the altar. The Catholic Church permits only baptised members in the state of grace (Catholics who are not in a state of mortal sin) to receive Christ in the Eucharist.

Many of the other sacraments of the Catholic Church, such as confirmation, holy orders, and holy matrimony, are generally administered within a celebration of Mass, but before the Second Vatican Council were often or even usually administered separately. The term Mass, also Holy Mass, is commonly used to describe the celebration of the Eucharist in the Latin Church, while the various Eastern Catholic liturgies use terms such as Divine Liturgy, Holy Qurbana, and Badarak, in accordance with each one's tradition.

Persecution of pagans in the late Roman Empire began during the reign of Constantine the Great (r. 306–337) in the military colony of Aelia Capitolina (Jerusalem), when he destroyed a pagan temple for the purpose of constructing a Christian church. Rome had periodically confiscated church properties, and Constantine was vigorous in reclaiming them whenever these issues were brought to his attention. Christian historians alleged that Hadrian (2nd century) had constructed a temple to Venus on the site of the crucifixion of Jesus on Golgotha hill in order to suppress Christian veneration there. Constantine used that to justify the temple's destruction, saying he was simply reclaiming the property. Using the vocabulary of reclamation, Constantine acquired several more sites of Christian significance in the Holy Land.

From 313, with the exception of the brief reign of Julian, non-Christians were subject to a variety of hostile and discriminatory imperial laws aimed at suppressing sacrifice and magic and closing any temples that continued their use. The majority of these laws were local, though some were thought to be valid across the whole empire, with some threatening the death penalty, but not resulting in action. None seem to have been effectively applied empire-wide. For example, in 341, Constantine's son Constantius II enacted legislation forbidding pagan sacrifices in Roman Italy. In 356, he issued two more laws forbidding sacrifice and the worship of images, making them capital crimes, as well as ordering the closing of all temples. There is no evidence of the death penalty being carried out for illegal sacrifices before Tiberius Constantine (r. 578–582), and most temples remained open into the reign of Justinian I (r. 527–565). Pagan teachers (who included philosophers) were banned and their license, parrhesia, to instruct others was withdrawn. Parrhesia had been used for a thousand years to denote "freedom of speech." Despite official threats, sporadic mob violence, and confiscations of temple treasures, paganism remained widespread into the early fifth century, continuing in parts of the empire into the seventh century, and into the ninth century in Greece. During the reigns of Gratian, Valentinian II and Theodosius I anti-pagan policies and their penalties increased.

Good Friday, also known as Holy Friday, Great Friday, Great and Holy Friday, or Friday of the Passion of the Lord, is a solemn Christian holy day commemorating the crucifixion of Jesus and his death at Calvary (Golgotha). It is observed during Holy Week as part of the Paschal Triduum.

Members of many Christian denominations, including the Catholic, Eastern Orthodox, Lutheran, Anglican, Methodist, Oriental Orthodox, United Protestant and some Reformed traditions (including certain Continental Reformed, Presbyterian and Congregationalist churches), observe Good Friday with fasting and church services. In many Catholic, Lutheran, Anglican and Methodist churches, the Service of the Great Three Hours' Agony is held from noon until 3 p.m.—the hours the Bible records darkness covering the land until Jesus' death on the cross. In the Catholic, Lutheran and Anglican traditions of Christianity, the Stations of the Cross are prayed in the evening of Good Friday, as with other Fridays of Lent. Communicants of the Moravian Church have a Good Friday tradition of cleaning gravestones in Moravian cemeteries.
