The word "lollapalooza" was used in World War II as a shibboleth to detect Japanese infiltrators, whose language habits obliterated the r/l distinction common in English. A shibboleth could be viewed as any cultural custom which makes one different. The members of God's true church have a distinctive shibboleth as we practice the weekly Sabbath or the annual holy days, putting them under the scrutiny of a society which treats those customs with contempt. As Christians practice love, displayed by keeping God's laws, they draw attention to themselves. It is necessary to continue to keep God's holy laws (our own non-verbal shibboleth), even when it hurts or proves embarrassing.
