Wednesday of Holy Week carries the informal name 'Spy Wednesday' — a medieval English designation recalling Judas Iscariot's agreement to betray Jesus to the chief priests (Matthew 26:14–16, Mark 14:10–11, Luke 22:3–6). The Synoptic Gospels place this arrangement two days before Passover, and the tradition of associating Wednesday with Judas's treachery is attested from at least the early medieval period. In the Byzantine tradition, this day is called 'Holy and Great Wednesday' and is associated with the anointing at Bethany (Matthew 26:6–13), where the woman's lavish devotion stands in deliberate contrast to Judas's calculating betrayal — the one pouring out costly nard, the other selling his Master for thirty pieces of silver. The Western lectionary tradition has varied over the centuries in which Gospel passage it assigns: some years emphasizing the anointing, others the conspiracy. The day also holds typological significance as the last 'ordinary' day before the Triduum begins at sundown on Thursday. In the early Church, Wednesday and Friday were already established as station days — days of fasting and prayer — which gave Wednesday of Holy Week a natural intensification of the regular Wednesday fast. The overlap with Passover preparation in Jesus's own time adds a further layer: as the Jewish community prepared lambs for slaughter, the Lamb of God was being handed over by one of his own.

The liturgical observance of Wednesday in Holy Week has been shaped by two parallel streams. In the East, the emphasis falls heavily on the anointing at Bethany and the contrast between devotion and betrayal; Byzantine hymnography for this day is rich with references to 'the sinful woman' who recognized Christ while Judas did not. In the West, the medieval tradition gave the day its popular name 'Spy Wednesday,' and the focus shifted more toward the conspiracy narrative. The BCP 2019 places this day within the protected days of Holy Week — no other observance can displace its propers. When the Annunciation (March 25) falls during Holy Week, it is transferred, illustrating the absolute liturgical precedence of these days. Some parishes observe Tenebrae services on Wednesday evening as anticipatory preparation for the Triduum, though the BCP itself assigns the principal Tenebrae elements to Maundy Thursday. The day serves as a hinge between the teaching ministry of Holy Week's earlier days (when Jesus taught in the Temple) and the Passion narrative that begins in earnest at the Last Supper.

John Donne was born in 1572 into a prominent Catholic family during the Elizabethan penal period. His mother was descended from the More family (John More's niece); his uncle was a Jesuit missionary. This Catholic inheritance—intellectual, spiritual, and dangerous—shaped his entire life. He was educated at Hart Hall, Oxford, and Lincoln's Inn, London, studying law and languages. In his youth he was a courtier, wit, and writer of erotic poetry (songs, satires) that circulated in manuscript among the literary elite.

At age nineteen he may have secretly married Ann More, ward of Sir George More; the marriage was acknowledged around 1601 and sundered his legal prospects. His most productive years (1600s–1610s) saw him in poverty and professional limbo, dependent on patronage. During this period he composed many of his Holy Sonnets (c. 1609–1611)—wrestling with faith, guilt, sexuality, and death—and his metaphysical love poetry.

In 1610 he published Pseudodoxia (a theological treatise) and began to secure patronage. A turning point came in 1615 when, at age forty-two and in financial desperation, he sought ordination in the Church of England. King James I, impressed by Donne's learning, encouraged him. He was ordained and rapidly rose in the Church: appointed chaplain to the king, then (1621) Dean of St. Paul's, one of the most prestigious ecclesiastical posts in England.

As dean (1621–1631), Donne preached an estimated 160 sermons, many surviving in print. These sermons—delivered from the famous Paul's Cross pulpit and in the Cathedral—combined learning (biblical, patristic, legal), innovation (vivid imagery, dramatic rhetoric), and theological depth. In 1624, seriously ill, he wrote his Devotions Upon Emergent Occasions, a sequence of twenty-three meditations, expostulations, and prayers following the course of a grave fever. This work, published posthumously in 1624, stands with the Preces Privatae as a masterpiece of Stuart devotional literature. Donne died on March 31, 1631, and was buried in St. Paul's; his last sermon, 'Death's Duel,' was preached the month before his death.

Donne had no medieval cult or formal canonization. His reputation rested entirely on his literary achievement and preaching fame during his lifetime. After his death, his works went through cycles of recovery and eclipse. The seventeenth and eighteenth centuries valued his sermons more than his poetry; the poetry was largely forgotten until nineteenth-century revival (T.S. Eliot's 1921 essays on metaphysical poetry resurrected Donne's literary reputation). Modern Anglo-Catholicism reclaimed him as a figure of integration—poet-priest, wit and saint, passionate and learned. His Devotions has been continuously reprinted and remains a standard spiritual text. His inclusion in Anglican calendars dates to nineteenth-century revival of saint commemoration and reflects modern rather than unbroken tradition. The Holy Sonnets, published posthumously (1633) and long attributed to his youth, are now recognized as written in middle age during spiritual crisis, making them central to understanding his conversion and faith.
