Holy Saturday is the day of Christ's rest in the tomb — the only day in the Christian year when the Church contemplates the reality that God the Son lay dead and buried. It is the third day of the Paschal Triduum, spanning from the evening of Good Friday to the lighting of the Paschal Candle at the Easter Vigil. Like Good Friday, no Eucharist is celebrated on Holy Saturday itself; the altar remains bare. The theological significance of this day was developed early. The Apostles' Creed's affirmation that Christ 'descended to the dead' (descendit ad inferos) finds its liturgical home here. The tradition of Christ's descent — variously called the Harrowing of Hell, the Descensus, or the Anastasis — is rooted in 1 Peter 3:18-20 and 4:6, amplified by early patristic reflection. An ancient homily attributed to the second century (sometimes called the 'Ancient Homily on Holy Saturday,' preserved in the Liturgy of the Hours) dramatically narrates Christ descending to the realm of death to liberate Adam and Eve: 'Arise, let us leave this place. The enemy led you out of the earthly paradise. I will not restore you to that paradise, but I will enthrone you in heaven.' The BCP 2019 provides two collects for this day: one focusing on the entombment and the hope of the third day, the other on the descent to the dead.

Holy Saturday is characterized by silence, waiting, and theological paradox. The Church holds a kind of cosmic Sabbath — God resting from the work of redemption as God once rested from the work of creation. The Byzantine tradition makes the most of this paradox, with icons of the Anastasis (Resurrection) that depict Christ standing on the shattered gates of Hades, pulling Adam and Eve from their tombs, even as his own body lies in the grave above. This icon is, notably, the Eastern Church's primary Resurrection image — not the empty tomb, but the harrowing of the dead. In the West, the day is marked by quiet preparation. The Easter Vigil, which begins after nightfall, is technically the first liturgy of Easter Day and belongs to the Resurrection rather than to Holy Saturday. The BCP 2019 makes this distinction explicit: the Vigil is listed under Easter rather than Holy Saturday. The hours before the Vigil are a genuine liturgical void — the Church waits, as the disciples waited, not yet knowing what the morning will bring. The ancient baptismal connection is strong: Holy Saturday was historically the final day of preparation for catechumens who would be baptized at the Vigil, their passage through water mirroring Christ's passage through death.

William Law was born in 1686 at King's Cliffe, Northamptonshire, the son of a grocer of respectable standing. He received an excellent education at Grantham School and at Emmanuel College, Cambridge, where he developed the classical learning and theological acuity that would mark his mature work. After ordination and election as a fellow of Emmanuel College, he served as chaplain and tutor—positions that promised a distinguished academic ecclesiastical career.

His life took a sudden and defining turn in 1714 when he refused to take the oath of allegiance to George I, declaring his conscience bound to the Stuart line. This act of principled nonjury cost him his fellowship and any possibility of preferment in the Church of England. Rather than retreat into obscurity, Law relocated to London, where he supported himself as a private tutor. He served for several years in the household of Edward Gibbon, grandfather of the historian, as chaplain and domestic tutor—a position that provided both security and the leisure to write.

During this period of apparent restriction, Law produced his greatest works. A Treatise upon Christian Perfection appeared in 1726, but it was A Serious Call to a Devout and Holy Life (1728) that would reshape Anglican spirituality and influence the broader Protestant world. The Serious Call is remarkable for its combination of theological sophistication, moral clarity, and vivid character portraiture. Law populated its pages with satirical yet sympathetic portraits—Flavia the fashionable woman, Calidus the businessman preoccupied with worldly gain, Miranda the truly devout—showing how ordinary Christians either evade or embrace the radical demands of Gospel charity and holiness.

The book's impact was immediate and profound. Samuel Johnson, then a young man adrift in spiritual uncertainty, credited reading the Serious Call with making him 'think in earnest of religion' for the first time. John Wesley reported that Law's teaching shaped his understanding of holiness and Christian perfection, though Wesley later diverged from Law's theology on several points. George Whitefield acknowledged Law's formative influence on his own spiritual awakening. The Serious Call became standard reading for Anglican ordinands, devout laity, and educated dissenting ministers throughout the eighteenth and nineteenth centuries. Its influence extended to figures as diverse as Samuel Taylor Coleridge and the Tractarian theologians of the nineteenth century.

In his mature years, Law returned to King's Cliffe, where he lived with extraordinary simplicity and ascetic discipline. He devoted himself to prayer, charitable work among the poor of the parish, and deep study of the German mystical theologian Jakob Böhme. This turn toward mysticism puzzled some contemporaries who had known him only through the moral and intellectual rigor of the Serious Call. To Law, however, there was no contradiction: the God who demands holy living and moral transformation is the same God who draws the soul into deeper union and contemplative knowledge. His later writings—The Spirit of Prayer (1749) and The Spirit of Love (1754)—explored this interior dimension of faith, seeking to show how systematic prayer and mystical awareness interpenetrate.

Law died peacefully at King's Cliffe on April 9, 1761, in his seventy-fifth year, having lived as a living embodiment of the devout and austere Christianity he had commended to others.

Traditionally, Law is remembered as a model of spiritual integrity and intellectual rigor in prayer. His insistence that Christianity demands the transformation of the whole person—commerce, dress, conversation, leisure—rather than sequestering piety to private devotion was revolutionary in its scope and influential across denominational lines. The tradition emphasizes not only his moral clarity but his growth into contemplative depth in his later years, suggesting that rigorous asceticism naturally flowers into mystical union rather than remaining sterile discipline.

Contemporaries and successors highlighted Law's personal integrity: he lived according to the demanding standards he commended in writing, neither accumulating wealth nor seeking preferment. His return to King's Cliffe and his dedicated charitable work among the poor established him as a figure of voluntary simplicity and genuine pastoral concern. Later Anglican tradition identified him as a precursor to the Tractarian movement, which similarly emphasized the integration of rigorous theological learning with deep spirituality and ascetic practice.

Law's influence extended beyond the Church of England. His writings were read and revered by Methodist, Presbyterian, and Congregationalist clergy. In the nineteenth century, Coleridge, the Tractarians, and later figures in the Catholic Revival found in Law a resource for integrating mysticism with Anglican ecclesiology and theology.
