Holy week teaches us about the final day of Jesus Christ being on earth, it talks about the triumphant entry of Jesus Christ into Jerusalem and how people praise Him. Holy week also explains to us how Jesus was betrayed and judged by portius pilat. Holy week is the week which Jesus was nailed on the cross, He died and on the third day He resurrected all this events took place and recorded in the holy bible.
Scripture does not command Christians to observe a specific annual Holy Week or prescribe special religious ceremonies for each day of the week. Therefore, Holy Week as a church tradition is not directly commanded in Scripture, even though the events it remembers are thoroughly biblical.
The Bible also teaches that Christians should not judge one another over the observance of particular religious days. Therefore, observing Holy Week can be considered acceptable for Christians who use it to reflect on the death and resurrection of Christ, provided it is not treated as a commandment from God.
