Did Jesus celebrate his birthday? How about Christmas?

Thank you for your question. Yes, every person who born into this world has a B-day. Is this the same for Christ? Please read my answer below. Thanks again for asking.

Bible says in Isaiah 9:6, “”For a child will be born to us, a son will be given to us; And the government will rest on His shoulders; And His name will be called Wonderful Counselor, Mighty God, Eternal Father, Prince of Peace.”

This was a prophecy fulfilled in the incarnation of Christ Jesus along with more than other 300 hundred prophecies from the Old Testament, regarding the coming of the Messiah/savior of mankind into the world. Did you notice the verse above said, “a child will be born to us, a Son will be given to us.” Father God gave His eternal Son to us for our salvation. Keep in mind, Christ’s beginning did not start at his incarnation. He became a man in His incarnation.
This is what theologians call, “Hypostatic union.” It explains how God, the Son of God, took human nature but He remained God at the same time. Jesus is called God-man. Jesus Christ was fully God and fully man in his incarnation. He came to earth and became a man but kept fully the divine nature in Himself. This full divine and human nature of Jesus is clearly evident in the Gospels in the Bible. Jesus wept at the tomb of Lazarus like a man but in next few moments, you ordered Jesus to come out the grace and Lazarus, the dead one for three days, came out of the tomb. (John 11:38 and 43). He was sleeping in a boat showing his full humanity and yet woke up and rebuked the wind and waves and all stopped and the sea became perfectly calm. (Mark 4:39). Jesus healed the sick with His word, controlled the nature with His word, resurrected people with His word, released the people from demon possession with His word. It was due to the fact of the hypostatic union, He was able to pay for humanity’s sin by His sinless and perfect blood on the cross. Jesus Christ can save anyone from their sins and grant eternity in heaven with God based on His death, burial, and resurrection on our behalf if one comes to Jesus in prayer and ask for forgiveness and salvation.
In short, Christ does not need to celebrate His birthday during his lifetime on this earth, simply because He does not have a beginning or the end. After all, what is the birthday of the eternal God? He is eternal Son of God. Jesus says, “I am the Alpha and the Omega, the First and the Last, the Beginning and the End.” Revelation 22:13. In another occasion Jesus said to the disciples, “Jesus said to them, “Truly, truly, I say to you, before Abraham was, I am.” John 8:48. Bible says also this about Jesus Christ as the eternal word of God in John 1 “In the beginning was the Word (Jesus), and the Word was with God, and the Word was God. He (Jesus) was with God in the beginning. Through him all things were made; without him nothing was made that has been made…..The Word (Jesus) became flesh and made his dwelling among us. We have seen his glory, the glory of the one and only Son, who came from the Father, full of grace and truth.” (John 1:1-3 and verse 14). The Word, Christ, the Son of God, was given to us. He pre-existed before all things, and hence for Him, there was no need to celebrate birthday being the eternal and everlasting God. In addition, there is no reference in the Bible that says Jesus celebrated His birthday. His humanity had a beginning point at the time of His birth but He was divine and God always and will always be.

Now people all over the world celebrate Christmas every year not to remember Christ’s birthday (I hope) but to remember and acknowledge the Son of God became a man for their sake to reconcile them to God the Father. In fact, Christmas is not viewed as a birthday celebration of Christ. On the contrary, on Christmas day, people of all continents, remember Christ, the Son of God, became a man and came to this earth to pay for our sins on the cross of Calvery to get us back to a loving fellowship and friendship with God. In this way, people celebrate His incarnation (that Jesus took the human nature along with His divine nature) and not His B-day per say.
Alternatively, we should remember Christ, His incarnation, His death, burial and resurrection as a ransom (price) for our sin each and every day of our lives. We should give thanks and praises to Him and to God the Father who sent Jesus to this earth on an ongoing basis. Bible, in fact, asks us to be thankful always. It says, “Always giving thanks for all things in the name of our Lord Jesus Christ to God, even the Father.” (Ephesians 5:20).
