What a much-needed commentary!
Editor Watterud asks what if your name was "Jim" and you heard people saying, "Oh, my Jim" all the time. Then she says:
"Now imagine that you are God. That scenario, where the name of God is used rather than 'Jim,' is played out in fast food restaurants and school hallways, at business meetings, baseball games and even at church dinners every day. People say God’s name, yet don’t want to talk to him. They exclaim 'Oh my God!' yet he’s no part of what they’re excited about. God is called upon and spurned within a single sentence countless times each day."
She ends her commentary this way:
“'You shall not take the name of the Lord your God in vain, for the Lord will not hold him guiltless who takes his name in vain' (Exodus 20:7)."
No one should say, "Oh, my G--," and we should tell that to people who do -- but always charitably and not self-righteously or sounding condemning, and in a way that indicates we do not have a personal beef with them, we are trying to help them do the right thing.
By the way, I should note that many people in Spanish-speaking countries say, "Dios mio," but more in the sense of a prayer and not in the way people say, "Oh, my G--" here.
