Recently I read Killing Jesus by (the now disgraced) Bill O'Reilly and Martin Dugard, which was released on September 24, 2013. While reading it I found this statement.
The Gospels of Matthew, Mark, and Luke make it clear that Jesus was celebrating the Passover meal a day early. ... Other scholars resolve the issue by arguing that the Synoptics base their calendar days on the Galilean Method (used by Jesus, his disciples, and Pharisees), from sunrise to sunrise; while John bases his calendar days on the Judaean Method (used by the Sadducees), from sunset to sunset. This resolves the discrepancy, as the different calendars will place Passover meals at different times. (p. 218.)This is completely different from what HWA's organization so confidently taught. As may be seen in Herman Hoeh's 1961 article, "The True Reason Why the Jews Rejected Christ," they insisted that the Last Supper was the Passover. They insisted that Passover is to observed at the started of Nisan 14. They insisted that the Jewish community are in error by celebrating Passover a day later. They insisted that this alleged error originated from Hellenistic Egypt. But can we really be so sure that HWA's organization were correct on this matter?
It is clear that HWA had little idea of the complexity of the topic of determining dates for the Jewish festivals when he so cavalierly adopted them in his syncretist religion. There is no requirement for Christians to observe the Jewish festivals. We should leave these festivals alone and let the Jewish community enjoy these festivals without the COGs appropriating them for themselves and audaciously insisting that the Jewish community fails to celebrate them properly. We should leave these precious festivals alone.
