Any takers on this?
I believe there is division on the "Begotten" aspect of Jesus.
Some believe He was not begotten until His Human birth... While others believe He was "Eternally Begotten". However, the phrase "Eternally Begotten" is not in scripture, and I have no understanding of what "Eternally Begotten" means.
I think "eternally begotten" was just a summary that's in the nicene creed. I think the authors of the creed were doing their best to sum up what scripture said, and that's a phrase they used among others ("light of light", "true God of true God", "eternally begotten, not made", etc..).
I think "only begotten son" as used in John (Jn 1:18, 3:16) refers to Jesus' uniqeness; His unique status.
In Psalm 2, the King is refered to as God's "begotten" son since the king had a unique status in relation to God and God's people:
Psalm 2:2 The kings of the earth set themselves, And the rulers take counsel together, Against the LORD and against His Anointed, saying ,
...
2:6 Yet I have set My King On My holy hill of Zion."
"I will declare the decree: The LORD has said to Me, You are My Son, Today I have begotten You.
And in Heb 11, Isaac is called Abrahams "only begotten son" as Isaac would be the son that the covenant was fulfilled through:
Heb 11:17 By faith Abraham, when he was tested, offered up Isaac, and he who had received the promises was offering up his only begotten son
I think John uses the term "begotten son" to refer at least to Jesus' status as Messiah and King, but I think Johns gospel takes it a step further and refers to Jesus as the "begotten son" in the sense that Jesus has a unique relation to the Father in that Jesus is somehow equal with Him; Jesus was the visible image of the invisible Father.
As far as why the nicene council attached "eternally" onto "begotten", I think it's fairly easy to see. There are several passages from which they probably got the idea of Jesus' eternality. The familiar ones being John 1, 8, 10, and 14 where Jesus says things about being "before Abraham" or Jesus was "the Word with God in the beginning", etc.. There are some more probably lesser known passages that show the same thing. Take an interesting passage from Jude which seems to place Jesus in the pillar of fire/cloud at the Exodus and possibly responsible for judgment on Sodom and Gomorrah:
Jude
1:4 For certain men have secretly slipped in among you men who long ago were marked out for the condemnation I am about to describe ungodly men who have turned the grace of our God into a license for evil and who deny
our only Master and Lord, Jesus Christ.
1:5 Now I desire to remind you (even though you have been fully informed of these facts once for all )
that Jesus, having saved the people out of the land of Egypt, later destroyed those who did not believe.
1:6 You also know that the angels who did not keep within their proper domain but abandoned their own place of residence, he has kept in eternal chains in utter darkness, locked up for the judgment of the great Day.
1:7 So also Sodom and Gomorrah and the neighboring towns, since they indulged in sexual immorality and pursued unnatural desire in a way similar to these angels, are now displayed as an example by suffering the punishment of eternal fire.
And there are other curious passages in the gospels that probably caught their eye:
Matt
11:19 The Son of Man came eating and drinking, and they say, Look at him, a glutton and a drunk, a friend of tax collectors and sinners!
But wisdom is vindicated by her deeds.
What did Jesus say that for?
Matt
12:42 The queen of the South will rise up at the judgment with this generation and condemn it, because
she came from the ends of the earth to hear the wisdom of Solomon and now, something greater than Solomon is here!
What does that mean?
Luke
24:27 Then beginning with Moses and all the prophets, he interpreted to them the things written about himself in all the scriptures.
John
5:45 Do not suppose that I will accuse you before the Father. The one who accuses you is Moses, in whom you have placed your hope.
79 5:46 If you believed
Moses, you would believe me,
because he wrote about me.
John
1:45 Philip found Nathanael and told him,
We have found the one Moses wrote about in the law, and
the prophets also wrote about Jesus of Nazareth, the son of Joseph.
Appearantly Jesus and some other people thought that Moses wrote about Jesus. Where exactly did they find that?
It's understandable that the people at the nicence council viewed Jesus as unique and somehow eternal. I think they figured the best way to reflect that was with the phrase: "light of light, true God of true God, eternally begotten not made". It's a hard thing to try to sum up in so few words and it seems to me that they did a pretty good job.
