when coffee becomes sin.

I guess going by certain standards anything could be considered a sin. Some people like to poke at coffee. When it comes to coffee, I drink as much as I like whenever I like and I thank the Lord for having provided me with coffee!

I'm one of those coffee snobs these days. Although, I couldn't pass up a bag of light roast at $2.50.
Try a glass, stainless, and ceramic mug and taste if you can tell the difference. If your coffee isn't too flavored, you will likely taste the polyurethane chemicals.

One of my pastors used to preach against coffee.
He wasn't even a Mormon, a Jehovah false Witness or a 7th Day Adventist.
That's one reason why the men would bring up his chocolate habit.
Chocolate was ok, but coffee was a sin.
II Hesitations 5:5

Chris Farley has the strongest coffee!

I don't understand why some worry so much about whether others are drinking too much coffee, listening to certain music, wearing certain clothes, and on and on and on. I just don't bother about these petty things. Now, I'm going to go brew some coffee.

Sorry I didn't explain. When I reread my post I might not have been clear.
The cleaner and more inert the container, the more your taste buds start detecting chemicals. When you ingest chemicals, the body gets accustomed to them.
Once I got a British Berkefeld Royal Berkey purifier a long time ago, my tap water started tasting awful. However, my health improved. There's not a hospital full of medical Drs in the country who would have figured out the cause of my health problems. They could have charged a hundred thousand dollars for tests and drugs/ chemicals and only made me worse.
Rather than going that miserable route, I used my own God given taste buds, personal records, and the knowledge God Himself provided to cure what ailed me. He gets the credit as the great physician.

Next, when using glass or ceramic (no lead glaze) mugs, eventually you will taste styrofoam as your built in detector gets recalibrated for those polyurethane chemicals. For non lead mugs, buy American made. Chinese is too risky.

Stainless has the benefits of durability if you use it for traveling, but the first two are best.

Enjoy your coffee.☕🙂👍

A little coffee is good for weight loss, sugar free. A lot of coffee causes Acid in the stomach which leads to multiple health problems.

If your coffee is too acidic, you aren't drinking good coffee.

tap into your willpower & problem solved! i drink about 3 to 4 cups of Jamaican Blue Mountain coffee per week, no problems!

There are so many health benefits related to coffee and it's be widely studied. Just drink and let it be I say.

Not a sin as, long as it is not decaf. This was covered thoroughly in the current Special Place in Hell for certain foods. I believe that it is currently #3 on the list (subject to change).
