There once was a church (not necessarily Baptist, but certainly Bible-believing) in the heart of Kentucky bluegrass country.  Most of the members of the community, but very few of the members of the church, earned at least part of their living by raising horses.  And beautiful horses they were, too--and fast:  they gave their owners many exciting hours at the race track.

But some of the members of our kindred church in the area--notably the older ones, who had long since stopped riding horses, and didn't even lean against the fences to watch them in the fields any more--some of these people were dismayed by the fact that most of the horses did end up racing, and that many people placed bets on those races.

So they decided that the only way to remedy the situation was to make sure that no one in the church had anything to do with horses.  The deacon board met and released a memo, directed primarily at the young people in the church.  This is a part of that memo:
 

. . . gambling is totally foreign to the Christian ethic.  We discourage contact with horses because:

(1) horses are instrumental in gambling;

(2) horses, like all domestic animals, are conducive to time-wasting;

(3) horses are offensive to many members of the church.

Most of the young people, of course, rebelled against this policy.  Many of them sneaked off to the fields to watch the horses running against the wind, manes and tails flying.  Some of them rode the horses, and one or two even placed bets on the races.  Some of the horse-lovers were caught, and were summoned before the deacon board, where they were told to mend their ways.

But some of the young people, unfortunately, swallowed the bunk about horses, and turned away whenever they saw them, after first giving their handlers looks filled with pity, for those people, obviously, were lost in sin.

Parables don't usually need explanations, but one is necessary in this case.  If you look at that memo again, and if you substitute "euchre decks" for "horses," and if you substitute "games" for "domestic animals," and "much of the constituency" for "many members of the church," you have a memo put out by the Bethel Student Services Office about card-playing--a memo which is just one instance of a policy against cards.

You don't have to substitute anything for the word "bunk."
