You can read the whole (short) piece at the Reformed Reader.
“…To sit day and night, pouring it [beer] in and pouring it out again, is piggish. This is not a human way of living, not to say Christian, but rather a pig’s life.”
“Eating and drinking are not forbidden, but rather all food is a matter of freedom, even a modest drink for one’s pleasure. If you do not wish to conduct yourself this way, if you are going to go beyond this and be a born pig and guzzle beer and wine, then…you must know that you cannot be saved. For God will not admit such piggish drinkers into the kingdom of heaven (Gal. 5:19-21). …Do not think that you are saved if you are a drunken pig day and night. This is a great sin…. Everybody should know that such sin is contrary to his baptism and hinders his faith and his salvation.”
“If you are tired and downhearted, take a drink; but this does not mean being a pig and doing nothing but gorging and swilling.”
