Who is a sinner?
My question was: Can a
believer return to being a
sinner?
You answered my question, with the understanding that the question you were answering is: Can a
believer return to being a
sinner?
A believer: someone who believes in Jesus Christ. A brother in Christ.
Obviously, that is what you understood, since you answered the question, with a
no.

Brethren, if anyone
among you wanders from the truth, and someone turns him back, 20 let him know that he who
turns a sinner from the error of his way
will save a soul from death and cover a multitude of sins. James 5:19-20
Remember, that the scripture states that Jesus is separate from sinners.
A sinner is a person who is lost, separated from Christ; without God: dead to God
For such a High Priest was fitting for us,
who is holy, harmless, undefiled,
separate from sinners, and has become higher than the heavens; Hebrews 7:26
Separate - Strong's G5563 - chōrizō
to separate, divide, part, put asunder, to separate one's self from, to depart
- to leave a husband or wife
- of divorce
- to depart, go away
The way we are reconciled to God is, we are cleansed from our sins.
But now in Christ Jesus you who once were far off have been brought near by the blood of Christ. Ephesians 2:13
When we, like one of His sheep, become lost, having wandered from the truth, we are in need of being "turned back" just as a sinner needs to repent, and turn to God.
The Holy Spirit says, that some will listen to doctrines of demons, and in doing so they will depart from the faith: depart from the truth.
Now the Spirit expressly says that in latter times some will depart from the faith, giving heed to deceiving spirits and doctrines of demons,
1 Timothy 4:1
