It would be unfair to question why we celebrate Easter, because the practice of observing special feasts in honor of God has existed since the time of the Israelites. The Bible shows that these celebrations were commanded by God and have maintained their significance over time.
In Exodus chapter 12, God spoke to Moses and Aaron in Egypt. He declared that the current month would be the beginning of months—the first month of their year.
God instructed the Israelites that on the tenth day of that month, every household should choose a lamb according to the size of the family. If a household was too small, they could share with a nearby family. The lamb had to be without defect, a male in its first year, taken from the sheep or goats.
They were also told to eat the meal in readiness—fully prepared, dressed, and alert—because it was the Lord’s Passover.
Passover is one of the sacred feasts of Israel. It later became known as “Pascha,” a name still used in some Christian traditions, including the Catholic Church. This feast is observed yearly at sunset on the 14th day of the first month, called Abib or Nisan.
This command was given while the Israelites were still in Egypt, before their deliverance. They had lived there for 430 years, and through this instruction, God set them apart and established a lasting memorial of their freedom.
