For this article to say "Today, all three Abrahamic religions (Judaism, Christianity and Islam) say that there is only one god," is not accurate, and is a false doctrine that caused the great persecution when Rome threw the Gods and Lords into the lion's dens and gladiator's rings of Rome. In English it says, "I said, you are Gods, sons of the Highest of all!" Psalm 82:6 Jesus also said the same in John 10:34-36. The ten commandments say that we are to have no other God before Yahweh because there are other Gods, there is only one Yahweh, but many Gods and Lords.
“Behold, the heaven and the heaven of heavens is Yahweh's your God, and the earth with all that therein too. Only Yahweh had a delight in your fathers to love them, and he chose their seed after them, even you above all people, as it is this day. Circumcise therefore the foreskin of your heart, and be no more stiffnecked. For Yahweh your God is God of Gods, and Lord of Lords, eldest God, a mighty, and a terrible, which regards not persons, nor takes reward. He does execute the judgment of the fatherless and widow, and loves the foreigner, in giving him food and raiment. Love you therefore the foreigner, for you were foreigners in the land of Egypt. You shall fear Yahweh your God, him shall you serve, and to him shall you cleave, and swear by his name.”
