Perhaps they should consider keeping both days. That way they can have at least some assurance that they on God's side of the international date line. It's hard to know for sure which side of that line is God-ordained, and which one is man's time.
That's what the Jewish Rabbi suggested, and then said "That's probably why Jews stay clear of Samoa".
Actually the simply thing to do is just follow the week as it is recognized in the country where you are.
August 18 Saturday will be observed the world over by Seventh-day Adventists. Why should Adventists in Samoa keep August 19 Sunday?
To me the issue isn't about datelines and longitudes etc. etc. though a rudimentary understanding of them is good and generally gives the correct order the world over, it's only in the Pacific where this issue arises.
But the bottom line is that the Sabbath is on Saturday (the day recognized as the day Christ rested in the tomb) no matter which side of the dateline the country is in.
Sunday is recognized by all the Christians (even the Adventists in Samoa who celebrated Easter on Sunday) as the day Christ rose from the grave.
Adventists in Samoa and Tonga have manufactured their own unique calendar that looks like this:
1Monday, 2Tuesday, 3Wednesday, 4Thursday 5Friday, 6Preparation Day (
Saturday), 7Sabbath
Basically they now have two Fridays every week and no Sunday at all in their self made calendar.
The whole thing makes about as much sense as someone going to New Zealand and just because they "lost" a day traveling in from America, they insist on keeping Sunday in Australia and ridicule Adventists for going to church on Saturday.
When EGW traveled from America to Australia she experienced a six day week.
Yet, while in Australia she kept Saturday, not Sunday as the Sabbath.
Sunday is the Papal Sabbath, observed by them, and will be enforced by them.
With all the prophecies we have concerning this, how can anyone justify that Sunday is the true Sabbath.
Now, my sister, . . . I write . . . to tell you that we are not to give the least credence to the day line theory. It is a snare of Satan brought in by his own agents to confuse minds. You see how utterly impossible for this thing to be, that the world is all right observing Sunday, and God's remnant people are all wrong. This theory of the day line would make all our history for the past fifty-five years a complete fallacy. But we know where we stand. . . . {3SM 318.4}
In other words - when the day line, or dateline is used to justify Sunday keeping as the right day it is a snare of Satan to confuse minds and make the Seventh-day Adventist message sound like a complete fallacy.
