We assume that the alcohol content today is the same as in Jesus’ day. In His day, a little water was often placed into the wine and thus decreased the alcohol content (cf. 1 Timothy 5:23) ... much like an O’douls today.
I left one of the baptist churches where I currently live because of the insistence of clinging to such tripe.
I can just hear them at the wedding feast: “Wow Jesus! This is the best watered down wine I have ever had!”
We just left a fundamental baptist church that taught that. It’s not the primary reason we left (nor the secondary or tertiary-alcohol is not that important to us) but false doctrine is false doctrine.
Drunkenness is always a sin.
Idolatry is always a sin.
Having a beer or glass of wine on a regular basis doesn’t automatically lead to drunkenness nor to making alcohol more important than our Lord.
New clothes don’t make one vain. Dessert every Sunday doesn’t make one a glutton.
In my life, I’ve observed the testimony of professing Christians hurt more by financial greed or immodest dress than by alcohol consumption. It hurts very much to hear unbelievers talk about how an outspoken Christian took advantage of someone financially.
