Here is a brief explanation of why we do not.

Is Christmas a celebration based on the Bible?

Date of the celebration
M’Clintock and Strong’s Cyclopædia says: “The observance of Christmas is not of divine appointment, nor is it of N[ew] T[estament] origin. The day of Christ’s birth cannot be ascertained from the N[ew] T[estament], or, indeed, from any other source.”—(New York, 1871), Vol. II, p. 276.

Luke 2:8-11 shows that shepherds were in the fields at night at the time of Jesus’ birth.

The book Daily Life in the Time of Jesus states: “The flocks . . . passed the winter under cover; and from this alone it may be seen that the traditional date for Christmas, in the winter, is unlikely to be right, since the Gospel says that the shepherds were in the fields.”—(New York, 1962), Henri Daniel-Rops, p. 228.

The Encyclopedia Americana informs us: “The reason for establishing December 25 as Christmas is somewhat obscure, but it is usually held that the day was chosen to correspond to pagan festivals that took place around the time of the winter solstice, when the days begin to lengthen, to celebrate the ‘rebirth of the sun.’ . . . The Roman Saturnalia (a festival dedicated to Saturn, the god of agriculture, and to the renewed power of the sun), also took place at this time, and some Christmas customs are thought to be rooted in this ancient pagan celebration.”—(1977), Vol. 6, p. 666.

The New Catholic Encyclopedia acknowledges: “The date of Christ’s birth is not known. The Gospels indicate neither the day nor the month . . . According to the hypothesis suggested by H. Usener . . . and accepted by most scholars today, the birth of Christ was assigned the date of the winter solstice (December 25 in the Julian calendar, January 6 in the Egyptian), because on this day, as the sun began its return to northern skies, the pagan devotees of Mithra celebrated the dies natalis Solis Invicti (birthday of the invincible sun).

On Dec. 25, 274, Aurelian had proclaimed the sun-god principal patron of the empire and dedicated a temple to him in the Campus Martius. Christmas originated at a time when the cult of the sun was particularly strong at Rome.”—(1967), Vol. III, p. 656.

For many years the Holiday was not celebrated in The United States and Congress has even been in session on Christmas Day.

In my opinion, some Christians mature in the Lord and recognize that these things are not to be reverenced.

For me, what matters is we celebrate Christs’ birth

And about the christmas tree and stuff…. do you believe in sanctification? We may sanctify non-Christian traditions as long as it does not do harm. Because the Christians adopted the tree tradition, the pagans do not do it anymore because we sanctified it therefore, that pagan ritual died. God owns everything, even culture and rituals and I believe that as long as it was given to God and does not harm any important doctrines, it is okay.

If we really want to take every thing from the Bible, then we should all eat unleavened bread. It does not also say in the Bible that we have to celebrate the Lord’s Supper every Sunday or every first Sunday of every month but we do it anyway. We should then all go to Jordan river to be Baptized.

For example, drums were used for pagan worship in Africa in the olden times but church use drums nowadays because it helps with the music and worship. It is also very effective in reaching out young people for Christ.

And the question is why would you or other people celebrate your birthday and not celebrate the birthday of the King? Though there is no date… I think it’s proper for Christians to celebrate Christmas one way or another, December 25 or not.

With the obvious symbolism for Pagans, it is easy to see why MANY of the virgin-born savior gods were said to have been born on December 25th in hopes of winning credulous and superstitious converts.

It was in 350AD that Pope Julius I "set" Christs birthday on December 25th to keep up this long tradition.

December 25th wasnt known as Christ’s birthday until 350 years after his birth.
Is a marketing tool folks. You have been had.

I know PLENTY of Christians who say that Christmas is for celebrating the birth of Jesus. Yet, Jesus wasn’t born on December 25, so that doesn’t make sense. I also heard Christians say that they celebrate Jesus and what he did for us on that day, but shouldn’t they be doing that *every* day? I mean, what is it about one day that gives you "more" reason to celebrate Jesus? It’s like you love your girlfriend/boyfriend more on Valentine’s Day just because it’s Valentine’s Day. Shouldn’t you love them *every* day?

I dunno. I guess it’s mostly due to tradition growing up. My parents are devout Catholics and they don’t celebrate Jesus at all on Christmas, so we just eat good food together as a family.
