And what precisely does Job 2:1 has to do what is recorded in Job 5:1 or Psalms? This isn't a pattern throughout the Bible. What is being ignored is that God calls believers, faithful or holy.
You're throwing out other words that has nothing to do with the term "saint" or "saints". I can't help it if the Church failed to read the scriptures before they decided on their classification of the term "saint".
When does Christ or God speak these specific words?
First it was meant to show that these terms are applied to angels and not to humans in Job 5:1 (the LXX says "holy angels"), just as other terms, such as in Job 2:1 the terms "sons of God" also apply to angels and not men. Second, it was meant to reiterate that nowhere in the bible does it say that all those who believe are "holy" or "saints" — except those written or influenced by +Paul, such as Acts, making it his personal innovation that no one used before or after him.
