剛同位基督徒嗌交

Don't be bothered too much by that.  He did not understand what the passage talks about.  Your Christian has to justify his/her case about the context and background of the passage in order to apply it to any case.  On what condition and situation do the passage apply?  I think your friend will have very difficult time to explain his/her case.  It is completely foolish and extreme in his/her application of the passage.  Tell him/her to speak less and pray more.  Apply the love of God to understand your situation instead of condemning your case will be a better case for him/her.
