In the movies, on tv, and amongst my peers, there is a much broader range of vocabulary to be heard. I have wrestled with this idea of polite language versus cussing or swearing. I have friends who openly swear with a clear conscience and those who won't even say "Oh my gosh." Biblical Counseling Guru Paul Tripp has some great thoughts on the subject. (If you like this, check out his website or any book he has written. I recommend Instruments in the Redeemer’s Hands: People in Need of Change Helping People in Need of Change.)
How do you define what language is appropriate to use? Is it merely cultural or also Biblical?
Also, do you distinguish between cussing (bad words) and swearing (using God's name in vain)?
