I had an argument with my brother about the scriptural teachings on consumption of alocohol,if it is morally and/or bibilically justified and if not then is it a sin?what do u guys think?

Well, I don't want to be drawn into this argument of drinking alcohol or not and whether is a sin or not BUT first, what is sin and what are things the scripture says is sin? If you know what sin is and what scripture calls sin, then you can say if drinking alcohol is a sin or not. You can do that assignment for yourself first.

Alocohol is what sef? Abi na alomo? Besides; either way its a sin.

The wine reportedly consumed by jesus in the bible must have been alcoholic i.e natural fermented wine.This alcoholic wine was used in the eucharist for centuries.Consumption of alcohol became a sin in christiandom at about the 19th century.
