Palm Sunday, celebrated in the Tridentine Rite of Mass, marks the beginning of Holy Week and commemorates Jesus' triumphant entry into Jerusalem. The ceremony begins with the blessing of palm branches, which the faithful hold while processing into the church, recalling the joyous welcome Jesus received from the crowds. The solemn High Mass that follows is filled with ancient chants, incense, and prayers, reflecting both the glory of Christ’s arrival and the sorrowful anticipation of His Passion. Through the traditional rite's rich symbolism and liturgy, Palm Sunday invites the faithful to meditate deeply on the mystery of redemption, preparing their hearts for the solemn events of Holy Week.
