It seems Constantine chose that dayte because it conincided with the exsting Roman celebration of Saturnalia here- you will note that date is not the 25th. Christmas isnt celebrated on the 25th everyehere, for example in some regions Epiphany in january is more widely celebrated. And although we tend to celebrate Christmas as the biggest celebration, Easter is in fact the definitive Christian occasion.
Christmas trees came to this country as a result of Queen Victoria and her Husband, rhe germanic origin is perhaps different but here they merely stem from a decorative tradition. You're right about Mistletoe though!
Your'e also right that the Bible doesn't mention birthdays- that's the approach taken by the JW as well. The thing is, the Bible isn't the textual guide ot faith in the way the Qur'an is- many things are nto mentioned in the Bible and it is not seen by the majority of Christians as the work of God whereas the Qur'an is of course the message of god through Muhammad. therfore, the fact that birthdays are omitted isn't necessairly the big issue in the way it could otherwise be.
i think ultimately, christmas has become a group celebration and way of giving thanks for the life of jesus, and indeed many other things in life- eg fmaily. Chreistians generally know that the Bible has been edited and colated by various people at avrious times, and know that the calendar isn't the most reliable. taht's not the issue- the issue is remembering what Christ stood for, the story that led to His birth, and celebrating it as the start of something very special to thsoe who beleive. dates / precise methods of celebration aren't as historically essential in Christianity as in other faiths perhaps and the early Church didnt seem to see the inclusion and derivation of symbolisms as particualrly bad either.
Indded, the sotory of Christ is present in different faiths (as in his birth, it is accepteed Christ existed- even in Islam IIRC). But tradition is such that it dosn't seem to matter.
i thnk ultiamtely if people saw the Bible as saying ' on this day you must do X Y and Z to commemorate' then Christmas would be different- but it doesn't. very few celebrations are prescrivbed in the Bible, the vast majority evolved. that's OK- its just the way it is.
BTW I shoudl declare that I am not a paactising Christian! I ahev beleifs leanbing towards Christinaity and a great respect for whT I think jesus emant as a person, but my awareness of the influence of the early Church on what is now percieved as Christianity means I have no faith in the organised format of the religion, if that makes sense?
i lime threads like this; force me to read my ntoes and relaise where the gaps are LOL!
