Final answer:
Jehovah’s Witnesses celebrate B) an annual memorial of Jesus’s last supper, aligning with the date of the Jewish Passover. They do not celebrate traditional Christian holidays like Christmas or Easter, and their observance of the Eucharist is unique to their beliefs.
Step-by-step explanation:
Jehovah’s Witnesses keep an annual memorial of Jesus’s last supper as a sacred festival. Unlike many other Christian denominations, Jehovah's Witnesses do not celebrate traditional Christian holidays such as Christmas, Easter, or Pentecost. This is because they believe these holidays have pagan origins or do not accurately reflect biblical teachings.
The Last Supper is a significant event in Christianity. It represents the final meal that Jesus shared with his apostles before his arrest and subsequent crucifixion. At this meal, described in the New Testament of the Bible, Jesus introduced the practice that would later become known as the Eucharist, also referred to as Holy Communion or The Lord's Supper. During the Last Supper, Jesus instructed his followers to use bread and wine to remember his sacrifice. This practice was meant to signify his body and blood, sacrificed for the sins of humanity.
Jehovah's Witnesses observe the Memorial of Jesus’ death once each year. This event corresponds to the date of the Jewish Passover, as it is believed that the Last Supper was a Passover meal. The Memorial is the only event that Jehovah's Witnesses celebrate in a manner similar to other Christian denominations' observance of the Eucharist.
Jehovah's Witnesses invite both members and the public to attend the Memorial, but the partaking of the bread and wine is reserved only for those who believe they are part of the 144,000 mentioned in the book of Revelation, a number thought to signify those who will reign with Christ in heaven.
When answering the question regarding the sacred festival that Jehovah’s Witnesses keep, the correct option would be B) An annual memorial of Jesus’s last supper.
