2Pink, wish I could say more that would help your situation; tho it sounds like you've gotten a pretty good 'handle' on it right now...
Borrowing from your cousin's post: "Turning it into a celebration or participating in pagan customs is the part that is wrong...." This comment always drives me up a wall, after the information I've found regarding the origins of the bible's teachings themselves... the bible itself has many Pagan beliefs and practices incorporated directly into its theology...
The Isra-EL-ites still carry the name of their original, so-called 'Pagan' god, EL, within their own name, used frequently in the bible... The Isra-EL-ites worshipped the golden calf and were disciplined for it. Within the same book, the Isra-EL-ites worshipped a BRONZE SERPENT lifted up on a pole, and were rewarded for it - and said 'bronze serpent' was later declared to be a MODEL for the MESSIAH - nonetheless, it was STILL IMAGE WORSHIP!!
The Isra-EL-ites venerated an erupting volcano as a manifestation of their 'god'... Neither the Isra-EL-ites nor their 'god' had a clue that it was actually a volcano; which indicates a woeful lack of information from the 'god' who supposedly 'built' the earth...
The so-called 'twelve' tribes of Isra-EL correspond with the twelve signs of the Zodiac - but one must also look at the Egyptian and Chinese zodiacs for the full picture...
The Isra-EL-ite 'sacred' number "7" was a sacred number in Goddess worship long before the Isra-EL-ites formed as a tribal group... Likewise with their number "3", which was used in Triple Goddess worship long before their 'god' existed...
That's just a sampling; what I am most familiar with at this point. Moving on to the New Testament...
The commandment of Jesus - "Take, eat, this means my flesh", and "Drink from this cup; it means my blood"... come from several different Pagan sources. The belief that the 'corn' died in order for 'Man' to live is a Celtic belief, among others. The belief that the wine represented a god's blood comes from the ancient, Pagan, Greek worship of Dionysus, which preceeded the jewish version by many hundreds of years. It was believed by the ancient Greeks that the harvesting, crushing, and turning to wine of the grapes, and the subsequent trimming of the grapevine, represented the death of the god Dionysus so that 'Man' might live... Oh, and Dionysus was 'hung upon a wooden cross'; that is, the grapevine is tied up to a wooden structure to force it to grow in a certain way...
It is also a throwback to the belief system of Animism; the belief that all things on earth have 'souls' or 'spirits', including the corn/wheat 'killed' for bread, and the grapes/grapevines 'cut off'/'killed' for wine... Propitiatory ceremonies were performed to 'thank' said grains and grapevines for 'giving up their life/lives' so that 'Man' might survive for another year... Native Americans often performed propitiatory ceremonies to their crops, animals they sought for food, and weather which controlled the size and conditions of their crops.
The belief that Jesus was 'in the grave' for 3 days, then resurrected, was originally a Semitic belief about the Goddess Innanna. The Babylonians believed their goddess Ishtar was ceremonially killed - or sacrificed herself - to enter 'the grave' for 3 days and 3 nights - after which she either resurrected herself or was resurrected by her consort or subservient god. These beliefs existed severa
