82:1 is just the tip of the iceberg, but it is what Jesus uses to counteract the accusations of blasphemy when He says He is the Son of God. He says, is it not written in your law I have said ye are gods and all of you are children of the Most High? How can you then say I blaspheme. He says the law cannot be broken.
As pointed out by the earliest church leaders, the Old Testament has numerous references to these gods or elohim. Most modern christians try to say these gods are idols or judges or such. But if they are judges, then Jesus' argument would make no sense. If they are idols, then passages like I am God of gods(idols) would become blasphemous. It is strange how those who claim to hold the Bible innerrant, will dismiss it when it disproves their unbiblical notions like that of the trinity.
Even our own church attempts to interpret such verses as meaning gods in embryo. The truth of the matter is that God said the Hebrews were gods and the law cannot be broken. The Bible also teaches there were angels already too, in passages like Jesus was made better than the angels, and was called God. Hebrews 1.
And those angels which kept not their first estate, are caught in everlasting chains. Jude. So they were angels before they came to earth and got their first estate, or if interpreted more broadly they were angels when they came to earth, but made it no further - without making future angelhood. I know it's not in gospel doctrine class, but it's in the Bible. I'm really not trying to be contentious - I'm just showing what the Bible really says about this subject that man has not understood - or at least forgot.
