What are the Commandments of God?
Adventists teach that the "commandments of God" in Revelation 12:17 and Revelation 14:12 are speaking about the Ten Commandments. If you look at the Greek word for "commandments" it is the word "entolas" which means teachings, instructions or commands. This word is used always in John's writings when He is referring to the instructions of teachings of Christ. When John refers to the Ten Commandments in his writings he uses a different Greek word, "nomas".
John also defines for us what the "commandments" of God are. Please look carefully at the following passages:
I John 5:2-3 - "By this we know that we love the children of God, when we love God and observe His commandments (entolas). For this is the love of God, that we keep His commandments (entolas); and His commandments (entolae) are not burdensome."
We aren't left to guess what the "commandments" are. The context of the Epistle tells us. Simply look at I John 3:22-24:
"and whatever we ask we receive from Him, because we keep His commandments (entolas) and do the things that are pleasing in His sight. This is His commandment (entolae), that we believe in the name of His Son Jesus Christ, and love one another, just as He commanded (entolaen) us. The one who keeps His commandments (entolas) abides in Him,..."
It's quite clear that the "commandments" of God are two:
1). Believe in the name of His Son Jesus Christ
2). Love one another
