Wine is called a mocker, but that is not the full description, I’ve had wine, and drinking half a glass did nothing for me, I did not become some “mocker”. This is talking about drinking excessively. Besides, it does not say DO NOT DRINK WINE, it just calls it a mocker.
As SDA’s we should know that we do NOT make a doctrine from one verse, you need to compare verses.

1 Timothy 3:2 & 3
An overseer, then, must be above reproach, the husband of one wife, temperate, prudent, respectable, hospitable, able to teach, not addicted to wine or pugnacious, but gentle, peaceable, free from the love of money.
1 Timothy 3:8
Deacons likewise must be men of dignity, not double-tongued, or addicted to much wine or fond of sordid gain,

If elders and deacons are not to touch wine, why would the Bible say an elder or deacon is to not to be addicted to wine, it would say not to drink any wine.

1 Timothy 5:23
No longer drink water exclusively, but use a little wine for the sake of your stomach and your frequent ailments.

If wine is forbidden, then why would Paul tell Timothy to drink a little.

Matthew 11:18 & 19
For John came neither eating nor drinking, and they say, ‘He has a demon!’ The Son of Man came eating and drinking, and they say, ‘Look at this glutton and drunkard, a friend of tax collectors and of sinners!’ But wisdom is vindicated by her actions.”

If Jesus was drinking grape juice then why would the people accuse him of being a drunkard? People know that you can’t get drunk on grape juice, they said this because he drank a little wine and they exaggerated it.

Then comes the Passover. Jesus kept the tradition of the Passover feast. Every Passover since the first one, the tradition was to drink 4 glasses of wine and eat lamb. Jesus ate lamb and drank wine. If he changed the tradition of the Passover, that would have been mentioned in the Bible.

Again, it is wrong to make a whole doctrine from one verse, especially one that is not saying what the doctrine says, it just says wine is a mocker, it does not forbid drinking it.
