Wow, it just doesn't dawn on you or James that you are actually sowing a world of trouble for yourselves by your private interpretation on this.Spot on James another excellent biblical response. There is no getting around the fact it was the Son who was the "angel of the Lord" in the OT since the Son said no man has seen the Father nor heard His voice. So that leaves us with Moses on the mount hearing the Son, not the Father.
@cjab is up a creek without a paddle on the identity of the angel of the Lord. He assumes wrongly that angel must mean a created being when many instances it refers to a messenger not an angel. Keep up the good work brother defending our Great God and Savior Jesus Christ who was the Angel of the Lord in the OT known as YHWH.
So here again is what the writer of Hebrews said about this and it would have made no sense at all for him to write this if God ever spoke by his Son in the OT or if the Son was one of the OT angels, so it is obvious that the writer of Hebrews did not hold your private interpretation about it.
1 God, who at various times and in different manners spoke in time past unto the fathers by the prophets,2 Hath in these last days spoken unto us by his Son, whom he hath appointed heir of all things, by whom also he made the worlds;
4 So he became as much superior to the angels as the name he has inherited is superior to theirs.
The first question you need to answer Civic and James, is when did Jesus become "ginomai" superior to the angels, being you believe he was God and never ceased to be God even while being a man? 5 For to which of the angels did God ever say,
“You are my Son;
today I have become your Father”?
“I will be his Father,
and he will be my Son”?
6 And again, when God brings his firstborn into the world, he says,
“Let all God’s angels worship him.”
Notice also, that God says "I will be a Father unto him and he will be my Son", so when did this happen, for in God saying "he will be", it is clear that there was a beginning to this and the passage tells you when it began also.
For it began on a specific day in creation time and that day was when he was brought into this world as the human heir of God (God's Son) and the writer also makes that clear in verse 6 and verse 4.
