God's 7th Day Sabbath...
God's seventh-day Sabbath is His gift to humanity from creation, was written into the Ten Commandments by God’s own finger, kept and taught by Jesus, and observed by the early apostolic assemblies. A memorial of both creation and redemption, God's Original 7th Sabbath should continue to be faithfully celebrated by believers now as a day of rest, worship, and well-doing.
What day is God's Original Sabbath?
THE HONEST TRUTH ... Despite doctrinal differences on various other topics, almost all Christians agree that resting one day in seven is an integral part of the Christian life. But does the word of God actually declare which day? "By the seventh day God had finished the work he had been doing; so on the seventh day he rested from all his work. And God blessed the seventh day and made it holy, because on it he rested from all the work of creating that he had done" (Genesis 2:2, 3). The very word "sabbath" means rest, and to rest implies that you have labored. It's logical, then, for God to have designated the last day of the week a day of rest. "The seventh day is a Sabbath to the Lord your God" (Exodus 20:10). Language reflects the customs of the culture that speaks it. Nearly every culture, from ancient through modern times, rested on the seventh day. As languages developed, the name for the seventh day of the week remained "rest day." In the mid 19th century, Dr. William Meade Jones created this "Chart of the Week," listing the name for the seventh day in 160 languages, including some of the most ancient. Even the Babylonian language in use hundreds of years before Abraham or the giving of the Ten Commandments at Sinai, calls the seventh day of the week sa-ba-tu, meaning "rest day." Today more than 100 languages worldwide, many of them unrelated to ancient Hebrew, use the word "Sabbath" for Saturday—and none of them designate any other day as a day of rest. Though the world's language groups have evolved so as to be unintelligible from each other, the word for the seventh day of the week has remained fairly recognizable.
Hasn't The Calendar Changed?
THE HONEST TRUTH ... Actually, we can be positive that our seventh day is the same day Jesus observed when He was here on Earth - the day He kept every week as the Sabbath. (See Luke 4:16.) The days of the week have never been confused. Here's why some people ask this question ... Before 1582, the world went by the Julian calendar, named for the Roman Emperor Julius Caesar, who implemented it in 46 BC. The Julian calendar had calculated that it takes the earth 365-¼ days to orbit the sun. However, it actually takes about eleven minutes less than that. Those eleven minutes accumulated each year until, by 1582, the calendar was 10 days out of harmony with the solar system. On October 4, 1582, Pope Gregory XIII issued a papal bull proposing a new calendar - the one we go by today - called the Gregorian calendar. As countries switched to the Gregorian calendar, they would 'lose' a number of days, bringing their calendar into closer alignment with the solar system. The longer a country waited to switch, the more days would be dropped. Most European countries switched right away, and they lost 10 days. For instance, Thursday, October 4, 1582, was followed by Friday, October 15, 1582 - not October 5. (The United States switched in 1752, making 11 days disappear. Turkey was the last country to switch, making the jump in 1927, and it lost 13 days.) Yet no matter how many days a country lost by switching to the Gregorian calendar, the weekly cycle was not affected at all. Friday still followed Thursday, and Saturday still followed Friday. The same seventh day remained. And because the weekly cycle is completely independent of the lunar and solar systems, we can be positive that when we rest and worship in observing the Saturday, it is the same seventh day on which the Creator rested, and on which Adam and Eve, the Israelites in the wilderness, Jesus, and the apostles, rested and worshiped.
Isn't There a "New Covenant" Now?
THE HONEST TRUTH ... The "New Covenant" in not the lawless absence of God's 10 Commandments. The Bible teaches in both the Old and New Testaments that the "New Covenant" is God's Law written into our hearts. God's 7th Day Sabbath is the 4th of His 10 Commands. Jeremiah 31:33 But this shall be the covenant that I will make with the house of Israel; After those days, saith the Lord, I will put my law in their inward parts, and write it in their hearts Hebrews 8:10 For this is the covenant that I will make with the house of Israel after those days, saith the Lord; I will put my laws into their mind, and write them in their hearts The New Covenant does not make us "lawless", it indelibly writes Gods Law into our innermost being.
