Actually, in deepest conscience, yes, I am troubled by the Apostle’s crede.
Was not King David also a Son of G_d
Psalm 2 Verse 7.
Or was he a liar?
I can understand your concern, I’ve done a bit of study in this and I think what is going on is you are misinterpreting the English, not like you’ve never heard that before but here goes.
You can actually follow this “problem” in the various Bibles if you have them.
Anyway if we go back to the Greek and Latin we see what was originally intended. The Greek says that Jesus is the monogenes of God, just like John 3:16. The Latin says unicum, basically our English word unique.
If you take the Old Latin manuscripts, they uniformly translate monogenes as unicum, both of course have form variations.
Anyway, along come Jerome, and he changes things. He leaves references to monogenes concerning human children as unicum, but he changes the references to Jesus to unigenitum which would literally be translated as “only begotten” some theorize he was influenced by another author he had read just before doing his translation.
Anyway this gives us only begotten for several references to Jesus, a change.which other translations followed right up to modern times.
It’s really a mistake, and word studies have shown that monogenes is based on mono or one, and genes but that genes is not from the word for begotten, gennao, but rather for the word for kind genus. And so we see translatons correcting that.
There’s been a general problem though. Only works very well for most human children. Monogenes is used to refer in scripture to several only children, they are unique, only really is an interpretation of how they are unique.
Problem is, we have two cases of monogenes where the person is not the only child. We have Jesus who is the only Son who is God, but not really the only son. Jesus is unique, one of a kind. And we have Isaac which really gives us understanding in scripture.
Heb 11:17 ESV
(17) By faith Abraham, when he was tested, offered up Isaac, and he who had received the promises was in the act of offering up his only son,
Only son is monogenes again. The problem is Isaac is not Abraham’s only son, his is however Abraham’s unique, one of a kind son, the son of the promise of God.
And so unique, just as it was done in the Latin in the Apostle’s Creed and just as done in the Old Latin was really the correct word.
As far as I know, only the ISV uses the word unique for monogenes at this time. And they are being criticized so vehemently for it that they are considering changing it. People don’t like it when you change their bible even when you are correct.
So anyway, i would at this point go back to the Creed and encourage you to realize that in it you are not confessing that Jesus is the only son of God, but rather that he is the monogenes Son, the unique Son, one of a kind.
Hope that helps.
