I just ran across the wonderful article below and heartily recommend it:
Reluctant Xtian: 5 Phrases I think Christians Shouldn’t Say
An excerpt:
Consider these phrases that I’ve actually heard:
“It’s not Christian to fire that person.” (Implication: A Christian can’t do some things because they’re seen as “mean”)
“It’s not Christian to think those sexual thoughts.” (Implication: A Christian isn’t sexual, or if they are, they don’t think about it because God hates sex and real Christians can control such things)
“You can’t do yoga! It’s not a Christian practice…” (Implication: A Christian can’t borrow from other faith traditions…or, apparently, stretch with intentional breathing on rubber mats)
“You can’t get a tattoo; it’s unchristian to defile the temple of God.” (Implication: God has an opinion about the tribal band around your ankle)
People say it all the time, and while a generous interpretation of their words might be to assume they are calling a specific action/thought into question, the reality is that they just end up calling the person doing that thought/action “unchristian”…to hurtful consequences. For those questioning or skeptical of faith, it erects another barrier, and further narrowly defines who is in or out of a relationship with God.
