It is serious, time consuming, and effort demanding. And it is well worth the effort, even if a person isn't able to better than the translation committees. It isn't my goal to produce yet another translation. It is my goal to understand the scriptures as well as I possibly can. And when I read technical articles that include sentences like "In the original Greek, this mean that instead of this...", I am able to at least have an informed opinion about it. I don't have to just take the writer's word for it. People write a lot of stuff, and not everything they write is accurate.
As I said, I wouldn't argue too much if someone really wanted to learn the language. There are possible benefits, and I wouldn't deny that either.
What I've seen happen is someone gets a smattering of Greek or Hebrew and from thenceforth is an authority on the subject, with comments like 'the Greek/Hebrew says this' etc etc.
Here's Grace's post. Is a perfect illustration of what I mean.
1 Ἐνἀρχῇἐποίησενὁθεὸςτὸνοὐρανὸνκαὶτὴνγῆν.
LXX
בְּרֵאשִׁ֖ית בָּרָ֣א אֱלֹהִ֑ים אֵ֥תהַשָּׁמַ֖ יִםוְאֵ֥תהָאָֽרֶץ׃
BHS (WTS)
1 בְּרֵאשִׁ֖ית בָּרָ֣א אֱלֹהִ֑ים אֵ֥ת הַשָּׁמַ֖יִם וְאֵ֥ת הָאָֽרֶץ׃
How much of it do you understand?
Of course, not everybody is like that, but it does happen.
But you raise a point about reading other people's stuff and wanting to have an informed opinion on the matter.
I am very much against the practice of reading other people's stuff. Especially where they comment on Gk or Hebrew. You can never know if they're right or wrong: useful or misleading..
How can you possibly know? Even if you've learned some of the language, it is improbable that you will ever be able to argue with them with any force.
It is far better to stay with the text of scripture and leave the writers alone. You will be led down many a garden path by them, and happily follow along, simply because you don't and can't know any better.
Sola scriptura is my war cry.
Look at it like this.
How many commentaries and versions etc etc did the very early church have? None.
How many authorities did Jesus, Peter and Paul quote? None.
And yet, we are happy to read this and that commentary, treatise, etc etc by people who may or may not know better than ourselves. Is that smart? I doubt it.
Why do it? What does scripture itself say?
'Oh how love I thy law. It is my study all the day'. 'To the law and to the testimony. If they speak not according to this word, it is because there is no light in them'. 'Sanctify them through thy truth: thy word is truth'.
Not a single mention of authorities etc in there, is there?
So SOLA SCRIPTURA is the most sensible attitude to take, and we should rejoice in it.
