Palm Sunday commemorates the triumphal entry of Jesus into Jerusalem (Matthew 21:1–11, Mark 11:1–11, Luke 19:28–44, John 12:12–19) and opens Holy Week. All four Gospels record the event: Jesus riding into the city on a donkey in deliberate fulfillment of Zechariah 9:9, the crowds spreading garments and branches on the road, and the acclamation 'Hosanna to the Son of David! Blessed is he who comes in the name of the Lord!' The palm branches, mentioned explicitly only in John's Gospel, gave the day its name; the other Synoptic writers mention 'branches cut from the fields' (Mark 11:8) or 'their cloaks' (Luke 19:36). The liturgical observance is ancient. The pilgrim Egeria, writing around 384, provides the earliest detailed description of a Palm Sunday procession in Jerusalem: the bishop rode from the Mount of Olives into the city while the people carried palm and olive branches, and children too young to walk were carried on their parents' shoulders, all singing 'Blessed is he who comes in the name of the Lord.' This Jerusalem stational liturgy — procession from a site outside the city through the gates — became the model for Palm Sunday observances throughout Christendom. By the seventh century, the practice had spread throughout the Western churches. The Bobbio Missal (7th c., Gallican rite) attests Gallican influence on the introduction of palm blessing into Western liturgy, and the ninth-century Romano-Germanic Pontifical codified the full Western pattern of palm blessing, procession, and Passion Gospel that persists in recognizable form to this day.

Palm Sunday is unique among liturgical days in sustaining two contrasting moods within a single service. The BCP 2019 preserves this ancient pattern: the liturgy begins outdoors (or at a station apart from the main church) with the blessing of palms, the reading of the Triumphal Entry Gospel, and a procession into the church with hymns of praise — typically 'All Glory, Laud, and Honor' (Theodulph of Orléans, 820). But once the congregation enters the church, the tone shifts sharply. The Eucharistic Gospel is the full Passion narrative from one of the Synoptic Gospels (rotating by lectionary year: Matthew in Year A, Mark in Year B, Luke in Year C — John's Passion is reserved for Good Friday). The congregation that moments ago cried 'Hosanna' now speaks the words of the crowd calling for crucifixion. This liturgical reversal — from royal welcome to the demand for blood — enacts the central paradox of the Passion: the King who was received with palms was dead by Friday. The BCP's introductory rubric makes the theological point explicit: 'We who hail Jesus as King one moment, may in the next deny him, even joining with the crowd in shouting, "Crucify him!"' The color is red — for the Passion, not for Pentecostal fire. Some parishes use violet through the early days of Holy Week and switch to red for the Triduum, but Palm Sunday itself takes red because the Passion Gospel dominates the Eucharistic liturgy. The palms distributed to the congregation have generated their own devotional tradition: many Christians keep their palms throughout the year, and the custom of burning the previous year's palms to produce ashes for Ash Wednesday creates a beautiful liturgical cycle linking the two days.

Thomas Cranmer studied at Cambridge and was appointed Archbishop of Canterbury in 1533. He oversaw the English Reformation's liturgical dimension, commissioning English-language Scripture and composing the Book of Common Prayer (1549, revised 1552), which replaced the Latin Mass with vernacular worship. The BCP's prose — the Collect for Purity, the General Confession, the marriage vows — remains among the finest in the English language.

Under Edward VI, Cranmer produced the Forty-Two Articles (1553) and advanced Reformed theology. He wrote the Defence of the True and Catholic Doctrine of the Sacrament (1550), articulating a Reformed eucharistic theology. His Homilies provided authorized doctrinal teaching for parish clergy.

When Mary I restored Catholicism, Cranmer was tried for heresy. Under enormous psychological pressure, he signed multiple recantations — genuine submissions reflecting real terror and theological uncertainty. But at his execution on March 21, 1556, he publicly retracted all his recantations, declaring his true Reformed faith. Eyewitnesses reported by Foxe record that he thrust his right hand — which had signed the recantations — into the flames first, crying 'This hand hath offended.' His final words were reportedly 'Lord Jesus, receive my spirit.'

Cranmer's legacy has been interpreted differently across traditions. Protestant tradition emphasizes his final retraction and martyrdom; Catholic accounts stressed his recantations as evidence of uncertain faith. Modern scholarship sees genuine human complexity — real fear, real faith, and a final act of moral courage.
