Priests are generally not allowed to abstain from alcohol all the time. They need a special dispensation to drink "mustum" rather than table wine during Mass. INTERESTING FACT ALERT
An interesting side topic , priests having to cover several parishes for Mass and the proposed introduction of a zero alcohol limit for driving .

In this particular example, I think Crazed Rabbit did an excellent job in showing that any subject can find some kind of quote in the Scriptures which appear to support a particular modern policy, illustrating quite clearly that they contribute very little to a meaningful debate, where the emphasis should be on facts rather than what other people have said.
That is a good answer .

The quote had validity. Someone stated that Jesus would have "probably" been pro-gun control, CR stated a contrary interpretation with a little more weight in the same area.
That however isn't a good answer since the flaw is in the use of a single line from a passage wheras the passage carries a different weight entirely .
