Relativists don't "interpret worng[ly]." They discard what they are uncomfortable with, or make unreasonable interpretations. To copy form my previous post:
You need not fear a slippery slope leading from a recognition of how to read a myth to the apostasy of the modernists who read everything as myth and deny the resurrection of Christ: There are passages of the bible to assert what is not only myth, but what is also history: Luke 1:1-4; John 20:30-31 and 21:24-25; 1st John 1:1-4; 1 Cor 15: 15-29; 2 Tim 2:18.
Passages such as those guide us away from discounting all of the bible as being myth, as modernists do.
There are distinctions that can be made as you assert. In my study of Biblical interpretation, I find the lion share of mistakes are made on the side of disregarding a straightforward reading. The majority of cults are founded by people who are both not grounded in scripture, and they fail to compare Scripture with Scripture as Isaiah admonishes.
Isa 28:9-10
Whom shall he teach knowledge? and whom shall he make to understand doctrine? [them that are] weaned from the milk, [and] drawn from the breasts.
10 For precept [must be] upon precept, precept upon precept; line upon line, line upon line; here a little, [and] there a little:
As the enemy of God flourishes through his wolves taking Scripture out of context:
Mat 4:6-7
6 And saith unto him, If thou be the Son of God, cast thyself down: for it is written, He shall give his angels charge concerning thee: and in [their] hands they shall bear thee up, lest at any time thou dash thy foot against a stone.
7 Jesus said unto him, It is written again, Thou shalt not tempt the Lord thy God.
So, if we compare scripture we find:
1. Jesus stated in uncertain terms that Adam and Eve were created at the beginning consistant with all revealed genealogies throughout scripture. (Mat 19:4-5)
2. Paul bases death on the original sin. (Rom 5:12 Wherefore, as by one man sin entered into the world, and death by sin;)
3. When Christ reigns on earth there will once again be no death. (Isa 11:7 And the cow and the bear shall feed; their young ones shall lie down together: and the lion shall eat straw like the ox.)
4. Jesus Christ has abolished death. (2Ti 1:10 But is now made manifest by the appearing of our Saviour Jesus Christ, who hath abolished death, and hath brought life and immortality to light through the gospel:)
Disregarding the Creation story representing Adam as the first man that brought death into the world, we no longer need a Savior, for death would be a natural event created by God's use of Evolution. Cains murder is justified in the animal kingdom because it would override the evil committed by his non-evolved soul.
The curse brought on by Adam's sin has made the entire creation groan.
Rom 8:21-23
21 Because the creature itself also shall be delivered from the bondage of corruption into the glorious liberty of the children of God.
22 For we know that the whole creation groaneth and travaileth in pain together until now.
23 And not only [they], but ourselves also, which have the firstfruits of the Spirit, even we ourselves groan within ourselves, waiting for the adoption, [to wit], the redemption of our body.
