Whatever is pure (Philippians 4:8)
Finally, brethren, whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good report; if there be any virtue, and if there be any praise, think on these things.
Christian preachers commonly demand not to do such-and-such because it's a sin, but is it really? Based on the (false) Protestant doctrine of total depravity people can declare almost anything as a sin. It's odd because these themselves do the same type of things. Examples: watching bad attitudes and violence on TV, or reading novels containing it.
In my view, it is useful to strive to avoid vice and to strive to practice virtue as a spiritual goal. Part of this is to immerse ourselves in holiness and purity. For example, it may not be a sin to want to understand the motives of the criminals and bad people in the news, but shouldn't we avoid filling our minds with such unwholesome ideas, images, and thoughts as they have in their minds?
