The chapter on "Birthdays" as found in the "[Human] Reasoning book is trite, mostly bunk, and deceptively misleading in that it makes statements that are contextually misapplied.
For instance the concluding sentence in the introduction says that birthdays "are not a Biblical practice" If that is the case then COs, Branch Overseers, WTS Presidents, Circuit Assys, District Assys, wedding rings on the left ring finger, driving cars, watching TV, eating pizzas, etc etc are'nt either. So what? You mean we should'nt do them? Where does one draw the line at unsuitability of practice, simply because it is'nt a "biblical" practice.
The [Human] Reasoning book misses the point of both the birthday celebrations mentioned in Scripture. Because blood was spliied on those days the conclusion is drawn that it is the PRACTICE that is condemned. By the same "reasoning" we could conclude that because so many people are killed by cars on the road, driving should be banned. The point is that "Bad Drivers" and not the act of driving are the culprits. The birthdays mentioned were of men who tended to violence as a way of life, and who would have used any occasion to assert authority. So - it is the men involved NOT the day that was to be shunned. If anything all the Bible is cautioning against is:Don't behead anyone on your birthday!
In the case of Pharoah's birthday, the point behind this, was'nt to tell us how bad the practice was, but that God in His prividence acted on that day. Pharoah's birthday was said to be on the "third day" [Gen 40:20. Third day? Third day of what? Well look at vs 19. Joseph was sharing a prison cell with two fellow inmates, one of whom was innocent, and one guilty. He then made a prophecy that in three days the innocent one would be vindicated, and the guilty party would pay for his crime by being hung.
Was this remarkable prophecy fulfilled? Yes, the Bible assures us, and in the most remarkable of circumstances, which even Joseph did not evidently forsee.[vs 22]
In the case of John the Baptist, it is assumed by the WTS that he was beheaded on that very day, of Herod's birthday. Nothing in the text allows us necessarily to draw that conclusion. Assumptions made by the WTS are distinctly imprecise when it comes to their dogma. They will leap down the throats of people who will assume that there were "three" wise men, but here at Herod's birthday they seem quite prepared to assume what the text does not choose to reveal. For all we know, John the Baptist could have been beheaded several days later and the head brought to Herod's daughter.
Most of the scholars quoted by the WTS in that article in the "[Human] Reasoning" are indeed quoted out of the contextual range that they were writing about. A thorough reading of these will reveal a far more balanced point of view. Many, like the International Standard Bible Encyclopaedia tell of many good things that were done on a rulers birthday, amnesties being granted, for instance [Vol 1, pg 515]
Jews have since antiquity, practised the celebration of the Bar-Mitzvah where a Jewish boy was considered to be a man on his thirteenth birthday. He was then said to be "Of age" Reference is even made of this in Jo 9:21 Without having kept some sort of record, the parents mentioned in that text would have had no idea when this had occured.
A word of caution regarding the "[Human] Reasoning" book: Like all the other humbug produced out of the cesspool that is WT Headquaters, it is not written to enlighten or even to inform. It is written to mould and influence. Like all good propaganda, it does not investigate the truth, but presents that version of its own platform which best suits its own purpose. The R&F are made to feel so self-righteous at not celebrating birthdays that they don't have time to investigate the harsher aspects ot the organisation they are primed to seve.
