What I find most hypocritical of the WTBTS is their insistence that the apostasy began shortly after the death of the last apostle and yet they cling to some apostate teachings.
There is evidence in the bible that the 1st century christians kept the torah just as Jesus and the apostles did including the 7th day sabbath. (If that had changed at all then there would have been some mention of it at the Jerusalem council but, there wasn't. There is biblical evidence that the Saturday Sabbath was kept.) In fact it was after the death of the apostles that the proto-Catholic Church decreed that the Sabbath instituted and sanctified by God would be, by their authority, changed to Sunday. Christians maintained the Saturday Sabbath until it became "uncomfortable" to be seen as showing any kind of Jewishness because of the persecution of the Jews by Rome. "At that time, Sunday was the rest day of the Roman Empire, whose religion was Mithraism, a form of sun worship. Since Sabbath observance is visible to others, some christians in the early second century sought to distance themselves from Judaism by observing a different day, thus 'blending in' to the society around them."
Constantine, who was a sun worshipper, legalized christianity and made the first Sunday-keeping law in AD 313. He enforced this law in the now "christian" empire in AD 321. "On the venerable Day of the Sun let the magistrates and people residing in the cities rest, and let all workshops be closed." (Codex Justinianus 3.12.3, trans. Philip Schaff, History of the Christian Church, 5th ed. (New York 1905), 3:380, note 1.) the Sunday law was confirmed at the Council of Laodicea in AD 364.
In their OWN Passover dogma as well as their continued adherence to apostate Sunday worship they certainly DO make the word of God void by their traditions of men. Boo...
