Our televisions, movies, media and social media seem to allow the bar to continue to be lowered.
While Christians are glad of the freedom to speak the gospel in a (relatively) free society, we also have some perspectives that put as more in the middle of the debate about free speech than at either end.
One perspective comes from Paul's dictum that, “All things are lawful,” but not all things are beneficial. “All things are lawful,” but not all things build up. (1 Cor 10.23). In other words just because we have the right to do something doesn't mean we should always do it. This statement by Paul comes in the context of considering the welfare of others who may have a different understanding of things to us.
The other perspective comes from the Christian's use of language. We believe God is a speaking God who has spoken through the prophets, who has spoken in and through his Son, and who now saves people through the speaking of the gospel. God is a communicating and speaking God, and language is a crucial way that Christians know God and tell others about God. So we want to make our language as good as we can. And we don't want to degrade the gift that God has given us to communicate his love.
When we speak in society about various issues we want to use language that is clear and understandable, but which reflects the character and heart of our God. So there are many ways of saying things that we will choose not to use. And perhaps others will copy us.
