You may even be involved in a prank today, but more importantly, since this is the Thursday before Easter, we celebrate today as Maundy Thursday.
Maundy Thursday is believed to be the day when Jesus celebrated his final Passover with His disciples. Most notably, that Passover meal was when Jesus washed the feet of His disciples in an extraordinary display of humility. He then commanded them to do the same for each other.
Christ's "mandate" is commemorated on Maundy Thursday---"maundy" being a shortened form of mandatum (Latin), which means "command." It was on the Thursday of Christ's final week before being crucified and resurrected that He said this commandment to His disciples. Jesus and his disciples had just shared what was known as the Last Supper and he was washing their feet when he stated:
"A new commandment I give to you, that you love one another: just as I have loved you, you also are to love one another" (John 13:34).
This new commandment raised the definition of love to a new and higher standard. Jesus sacrificially met His followers' deepest need---that of new spiritual life and the forgiveness of sins. He even loved His enemies, and He calls us to show love to those who don't appear to deserve it. Just as Jesus loved sinners "to the end" (or "to the max" John 13:1) when He had nothing to gain from them, so must we. The Bible says that there was nothing attractive about sinful mankind that drew Him to love us. God loved us while we were yet sinners (Romans 5:8). Salvation is not only a wonderful gift that protects us from the penalty that we deserve Romans 6:23 , the work of Christ also embues new life, grants spiritual strength, and motivates godly action in those who believe:
"For the grace of God has appeared, bringing salvation for all people,12 training us to renounce ungodliness and worldly passions, and to live self-controlled, upright, and godly lives in the present age,13 waiting for our blessed hope, the appearing of the glory of our great God and Savior Jesus Christ,14 who gave himself for us to redeem us from all lawlessness and to purify for himself a people for his own possession who are zealous for good works." (Titus 2:11-14)
While Scripture doesn't forbid us to commemorate days like Maundy Thursday, the main question is are we observing Christ's new command to love---especially those who deserve it least?
"Beloved, let us love one another. For love is from God, and whoever loves has been born of God and knows God. Anyone who does not love does not know God, because God is love." (1 John 4:7-8)
Many churches observe Maundy Thursday with a Communion service and often a foot-washing ceremony. These traditions help Christians reflect on the sacrifice of Jesus and his commandment for us to love and serve others.
Often, during communion, a pastor will read the following passage about what happened on the events of Maundy Thursday:
1 Corinthians 11:23-26: "For I received from the Lord what I also passed on to you: The Lord Jesus, on the night he was betrayed, took bread, and when he had given thanks, he broke it and said, “This is my body, which is for you; do this in remembrance of me.” In the same way, after supper he took the cup, saying, “This cup is the new covenant in my blood; do this, whenever you drink it, in remembrance of me.” For whenever you eat this bread and drink this cup, you proclaim the Lord’s death until he comes."
Every time we participate in communion, we recognize what happened during the events of Maundy Thursday. That our Lord Jesus was betrayed, to be tried and crucified the next day on Good Friday.
Luke 22:27-38 - "When the hour came, Jesus and his apostles reclined at the table. 15 And he said to them, “I have eagerly desired to eat this Passover with you before I suffer. For I tell you, I will not eat it again until it finds fulfillment in the kingdom of God.” After taking the cup, he gave thanks and said, “Take this and divide it among you. For I tell you I will not drink again from the fruit of the vine until the kingdom of God comes.” And he took bread, gave thanks and broke it, and gave it to them, saying, “This is my body given for you; do this in remembrance of me.” .."
