Easter is the feast of the Resurrection of Jesus Christ from the dead — the oldest, highest, and most central celebration of the Christian year. Every other movable feast and fast is calculated from it; every Sunday is a weekly Easter. The date is determined by the Paschal computation established at the Council of Nicaea (325): Easter falls on the first Sunday after the first full moon on or after the vernal equinox (March 21), placing it between March 22 and April 25. The earliest Christians appear to have observed an annual Pascha from a very early period, though the precise origins are debated. The Quartodeciman controversy of the second century — whether to celebrate the Pascha on Nisan 14 (regardless of the day of the week) or always on a Sunday — attests that the observance was already widespread and deeply important by the mid-100s. Polycarp of Smyrna reportedly discussed the matter with Anicetus of Rome around 155 (Eusebius, HE 5.24), and the issue was sharp enough to prompt Victor of Rome to threaten excommunication of the Asian churches, a threat moderated by Irenaeus's famous appeal for peace. The Nicene resolution in favor of the Sunday observance became universal in the mainstream Church, though some groups maintained the Quartodeciman practice for centuries. The Great Vigil of Easter is among the most ancient liturgies in Christianity, with roots traceable to at least the third century (Apostolic Tradition). By the fourth century, Egeria describes an elaborate Jerusalem vigil with baptisms, and Augustine attests a similar pattern in North Africa.

The Great Vigil, which the BCP 2019 describes as 'the first liturgy of Easter Day,' begins in darkness. The Paschal Candle is lit from new fire — a symbol of Christ as the light of the world entering the darkness of the tomb. The Exsultet, the great hymn of praise to the Paschal Candle, is among the most magnificent pieces of Christian hymnody, attested from at least the fourth century (Ambrose may have composed an early version). The vigil readings trace salvation history from creation through the Exodus to the prophets, building to the proclamation of the Resurrection Gospel. Historically, the Vigil was the primary occasion for baptism — new Christians dying and rising with Christ through the waters, emerging to receive their first Eucharist on the night of the Resurrection. The BCP 2019 provides for baptism or renewal of baptismal vows at the Vigil. The Easter morning liturgy opens with the Paschal greeting: 'Alleluia! Christ is risen! / The Lord is risen indeed! Alleluia!' — a form attested across virtually every Christian tradition. The fifty days of Eastertide that follow (through Pentecost) are treated as a single unbroken feast — no fasting, no kneeling for prayer, Alleluias throughout. Easter eggs, the custom of which is documented from at least the thirteenth century, symbolize the sealed tomb and new life breaking forth. Easter is not a day but a season.

Frederick Denison Maurice was born in 1805 near Lowestoft, Suffolk, into a Unitarian family. His childhood was marked by religious turmoil — his mother and sisters converted to various forms of evangelical Christianity, and the household was divided by competing convictions. Maurice himself was received into the Church of England in 1831 and ordained in 1834.

His major theological work, The Kingdom of Christ (1838, revised 1842), argued that the Church's visible structures — creeds, sacraments, episcopacy — are signs of a universal spiritual society that God has already established in Christ. This vision was neither Catholic nor Protestant in the conventional sense: Maurice believed that every party in the Church held part of the truth, and that the Church's calling was to manifest the unity that already existed in Christ rather than to create it.

In 1848, inspired by the Chartist movement and the failure of revolutionary politics, Maurice joined with Charles Kingsley and J.M. Ludlow to found the Christian Socialist movement. Their argument was that competition was unchristian, that cooperation was the economic principle implied by the gospel, and that the Church had a duty to engage with the social conditions of the working class.

Maurice's dismissal from King's College London in 1853 — for publishing Theological Essays, in which he questioned whether 'eternal' in 'eternal punishment' meant 'everlasting' — made him a cause célèbre. He founded the Working Men's College in 1854 and was eventually appointed to a chair at Cambridge, where he taught until his death in 1872.

Maurice's legacy in Anglican theology and Christian social thought was established immediately and has grown continuously. The Working Men's College he founded remains active and influential. His theological vision — emphasizing the universality of Christ's redemption, the present reality of God's kingdom, and the Church's responsibility to engage with social structures — became foundational for Anglican social ethics. Christian Socialism, which he helped launch, became a major current in Anglican thought. His willingness to question the doctrine of eternal punishment — which led to his dismissal — was later vindicated by theological development. The tradition presents Maurice as a prophetic figure who paid a price for intellectual and social honesty, and whose vindication came gradually through the acceptance of his ideas and the success of his institutions.
