Christians celebrate Passover too in their very own special way.
However, they have a different religious significance for the Pesach
holidays. Jesus has been depicted as the final Passover Lamb in the New
Testament of the Bible who was sacrificed to free us spiritually from
the slavery of the sins just like the lamb had once been instrumental in
physical deliverance of Hebrew slaves from bondage in Egypt. Thus, for
Christians, Passover celebration is a memorial and tribute to Jesus for
his great sacrifice and tortures that he suffered for the mankind.
Though different groups have little variations of Passover celebration
that they follow, most of them follow the rituals of the Last Supper as
stated by Jesus to his disciples.
The unleavened bread was to represent Jesus' body and wine to represent
his blood and the New Covenant. Jesus himself took the place of the
traditional lamb. Some Christians even follow the ceremony of washing
one another's feet just like Jesus did to his disciples at the Last
Supper. The time to celebrate Passover in Christians differs too. Some
groups observe the celebration on the night before Jesus's suffering
when He held his Last Supper while others observe it at the time when he
was sacrificed and died 'at the ninth hour' in the evening that
coincides with the time when Jews used to sacrifice their Passover
lambs.
