Pontius Pilate was the Roman governor of Judea. His family background was from south-central Italy, so his traditions were entirely Roman, not Jewish. As governor of Judea, he had to be aware of the major Jewish festivals, because they were times of heightened tension and civil unrest in Jerusalem -- simply because of the pilgrimages to Jerusalem taken by a large fraction of the Jewish population on the festivals. He would likely have "observed" the festivals by putting his troops on heightened alert.
The same way that all other Jews observe Pesach (Passover).
Yes that was the custom; on Passover Day one prisoner would have to be released. Pilate wanted Jesus to be free, but the crowd wanted Barabbas free, and he was set free at the cost of Jesus.
Jesus observed Passover, as he was Jewish. Easter did not exist then. It was his resurrection that created Easter.
The passover is celebrated by Jews as it reminds them of their freedom from slavery. <><> Yes, Christians observe Passover. See the Related Link below.
Passover is a Jewish tradition, not Catholic. Catholics observe Holy Thursday, the Mass of the Last Supper.
Jewish law doesn't permit fasting during Passover.
Jews observe what is written in the Torah. Period.
No, Bararabbas was the one that was to be released after the Passover. It was a traditioon that one be set free after the passover. Pilate offered Jesus as the one to be released after the Passover but the people requested Barrabas. As the passover was not complete, he would have still been in jail. See Luke 23:18
Relative civil quiet at a time (Jewish Passover) when civil unrest might have been expected.
Wrong. The seder is held at home, and the special festival prayer-services are held in the synagogue.
Roman Catholic AnswerYes.
Pontius Pilate released Barabbas from prison, as part of a custom during Passover to free a prisoner chosen by the crowd. Barabbas was a notorious criminal, and his release occurred instead of sentencing Jesus to crucifixion. This event is documented in the New Testament Gospels, highlighting the choice made by the crowd.
