Gday Thirdwitness, I havent replied to any of youre posts until now so welcome,
Im an SDA and there are some similarities with in biblical interpretation with the JW positions.
Many SDAs interprete Daniel 8.14 with Daniel 9 requireing the day for a year principle to arrive at 1844
Also the three and a half years is applied to 538 to 1798 the dark ages useing the day for a year principle.
More informed scholars see no necessity to use the day year principle in Daniel 9 because in the context of this chapter the caculation is 7 times 70 years. In fact the SDA bible commentry as well as other good commentries say the day year principle is not required here.
The year day is used pragmatically.
In predictive prophecy the year day principle is not used if it looks silly. eg when Jesus said he would die and in three days he would raise it up the principle is not used. It isnt used with the three and a half years by the JWs but is used by the SDAs with the SDA interpretation. It isnt used with the millenium because the interpretation would seem too long.
Suffice to say Im an SDA who couldnt go along with such an inconsistant and strange rule.
