Paul objected to the spiritualizing of prophecy that was to have a physical fulfillment.
He pointed out that the physical fulfillment of the Resurrection has not happened.
The mistake in translation from the Greek to English happened hundreds of years ago and fools have been deceived by it ever since.
There is no mistake - the word dividing can also refer to doling a thing out, and was often the case in its use in that way in the Middle Ages.
As in its use in the following...
1 Corinthians 12:11 But all these worketh that one and the selfsame Spirit, dividing to every man severally as he will.
Different Greek word, same sense, thus, the same English word in both.
And within the context of 2 Timothy 2:15, both meanings are obviously intended.
Note...
2 Timothy 2:14 Of these things put them in remembrance, charging them before the Lord that they strive not about words to no profit, but to the subverting of the hearers.
That right there involves doling or dividing a thing out to others...
Our "CUT to the chase; give it to them STRAIGHT" carries that sense.
But it also implies dividing from the one, or not dividing into the other.
As do verses 15 and 16.
2:15 Study to shew thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing the word of truth.
Do that BUT AVOID doing the following...
2:16 But shun profane and vain babblings: for they will increase unto more ungodliness.
That is a division between those two.
A critical one. For of those two...
2:17 And their word will eat as doth a canker: of whom is Hymenaeus and Philetus; 2:18 Who concerning the truth have erred, saying that the resurrection is past already; and overthrow the faith of some.
Yep, they deviated, or divided from how things are laid or divided out in Scripture, to their own not only vain or baseless babbling, but where theirs was basically a profanity.
Paul then divides between things some more, twice...
2:19 Nevertheless the foundation of God standeth sure, having this seal, The Lord knoweth them that are his. And, Let every one that nameth the name of Christ depart from iniquity.
He then divides, or notes, another distinction between the things that differ that he is pointing out through CONTRASTS...
2:20 But in a great house there are not only vessels of gold and of silver, but also of wood and of earth; and some to honour, and some to dishonour.
Acts 17: 11, 12.
