Tonga SDA churches keep Sunday as Sabbath

"Tongans are scrupulous observers of the Wesleyan Sabbath, and it is possible to be arrested for fishing on Sunday. Even the Seventh-day Adventists, who elsewhere take Saturday as their Sabbath, here observe the Sabbath on Sunday. The local Adventist pastor explained his church’s stand to me.

"‘When God made the world, He made the day go from west to east,’ he said. ‘On the map, the so-called Date Line actually makes a jog to the east here. We maintain that what is called Sunday in Tonga is actually Saturday, since we are really on the eastern side of the Date Line [if it ran in a straight line]."—Luis Marden, "The Friendly Isles of Tonga," National Geographic, March 1968, p. 358.
