I see man-made "holidays" as all the same. I don't think having a holiday is all bad, it's what you make of it and what you chose to do. You shouldn't allow anything that you do seperate you from Christ. Like Shimie stated with Halloween, some chose to do evil, she however, decided to do something more positive with her students...etc. all the other wonderful suggestions.
The Bible never told us to "celebrate" these man-made holidays. That goes for Christmas and Easter too.
Christmas is never mentioned in Biblical text, but is a fabricated story derived from the birth of Christ based on some truth, some imagination, a dash of license of facts and what is true is often exaggerated. It is celebrated at December 25th since it is not mentioned in scripture and therefore is not tied to any dated Biblical historical event in time.
It is true Christ was born, but his birth date has been attributed to practically every month of the year and most likely is akin to the early fall based on the events of the story.
There were no three wise men, Christ was not born in a manger, and he was close to two years old and living in a house by the time the Magi (Wise men) arrived.
"Easter" is a mistranslation by the King James Version translators. All other reputable versions employ the proper title of "Passover" in Acts 12:4.
The title "Easter" is a variation of several pagan celebrations in honor of Goddesses of fertility, which is why it probably occurs in the spring and is associated with the new life in the animal (bunnies and eggs) and plant world.
Passover and Easter often do occur at the same time of each other, but may be as much as a month a part.
Their observance is entirely different.
Passover was for the Jews to celebrate the "passing over" of the death angel just before the Exodus to persuade Pharaoh to let the Jewish people leave Egypt after 400 years of slavery.
Easter, as it is called, is supposed to be celebrated on the first day of the week, following His death 3 days before.
It is observed with variations of date due to different calendars on the the first Sunday after the full moon on, or next after March 21, or one week later if the full moon falls on a Sunday. (Webster)
However, Easter was not even heard of until the 2nd century making it foreign to the scripture’s writers of the first century.
Some New Testament blood covenant Christians celebrate the holiday season with a tree and lights and presents --- mostly for the kids --- because they have hard time differentiating "why not to". Some feel awkward if they don't mimic their neighbors.
But since these festivities are not in the Bible, most blood covenant Christians do not celebrate religious holidays where none exist.
Paul commented on people who observe such days.
In one scripture he said:
"You observe days and months and seasons and years. I fear for you, that perhaps I have labored over you in vain. Gal 4:10-11
But then his kindly heart told us this in Romans 14:
1 Now accept the one who is weak in faith, but not for the purpose of passing judgment on his opinions.
2 One man has faith that he may eat all things, but he who is weak eats vegetables only.
3 Let not him who eats regard with contempt him who does not eat, and let not him who does not eat judge him who eats, for God has accepted him.
4 Who are you to judge the servant of another? To his own master he stands or falls; and stand he will, for the Lord is able to make him stand.
5 One man regards one day above another, another regards every day alike. Let each man be fully convinced in his own mind.
6 He who observes the day, observes it for the Lord, and he who eats, does so for the Lord, for he gives thanks to God; and he who eats not, for the Lord he does not eat, and gives thanks to God.
7 For not one of us lives for himself, and not one dies for himself;
8 for if we live, we live for the Lord, or if we die, we die for the Lord; therefore whether we live or die, we are the Lord's.
The death burial and resurrection of Christ is to be celebrated by covenant Christians every first day of the week by partaking of the Lord's Supper. This is the example following by Christians in the New Testament. When we do that, the Lord's Supper becomes a covenant renewal ceremony. Each time, we renew our original blood covenant agreement we made with Him in baptism.
Every covenant back to Adam and Eve was ratified by blood. Our covenant with Christ’s blood was ratified when we died and were resurrected with Him in baptism. At that instant, we had all sin removed and it placed us in a saved condition.
Do I pratice or celebrate any of these holidays? The answer is no. Do I judge those who chose to partake of these holidays? NO, I do not. In this regard, I chose to follow Christ and not man as it applies to rituals and pratices.
I hope that all those who are out on this coming holiday (whatever your plans may be) do pratice safety.
