I'm wondering about some of what has been said here. Isn't it possible that seeing porn is different for someone who has never been addicted to it than it is for someone who is addicted to it? You know, much like some people can casually drink alcohol from time to time and not become drunks, but alcoholics must stay completely away from it or they fall right back into drunkenness. And of course, just like we have a responsibility not to knowingly tempt an alcoholic with alcohol, we can't knowingly tempt a porn addict with porn either!
Now I've never watched porn with my wife as a sexual stimulant, and I certainly wouldn't think watching it would be a good testimony to my neighbors. But I want to play a little devil's advocate here to try to get some really solid scriptural answers:
Why is porn so sinful if not abused? We are told that nothing is unclean for us, although not everything is expedient.
Of course, this doesn't apply to those things which we are clearly told are sinful, such as murder. But there is no commandment stating "Thow shalt not watch porn" (or whatever the equivalent would have been at the time the commandments were given. Watching harem girls dance, perhaps?)
It is not necessarily condemned as lust. The type of lust the Bible condemns is a "strong desire that supersedes your desire for God". Porn
can become this type of lust, but
doesn't have to, any more than the desire for many other things can become lust that supersedes our desire for God. Money comes to mind right away!
It is not adultery. Adultery is the use of sex to
steal another's spouse. Probably most people that watch porn never actually meet any of the actors/actresses and have real sex with them for the purpose of taking them away from their spouses. Nor do most rational people actually believe this would ever happen to them. (Fantasy and belief are
not the same thing!) Maybe it's possible that someone could watch porn and actually develop a lust for the person in the movie to the point that they think they may get the chance to actually commit adultery with them, but that would be the exception, not the norm. This type of person would probably be already "committing adultery in their hearts" with many other people that they see on a daily basis as well, so it's not logical to put all the blame for this on porn.
It's also not fornication, since there is no real sex involved between the watcher and the actors/actresses, especially no sex involving idolatry, which is a part of fornication.
I've been in situations where, for legitimate reasons, I have seen porn, have been present for a brief time during the actual filming of some of it, and have also been around other related activities that most on here would probably condemn. But I did not sin. I did not loose control over myself and lust after the ladies to the point that the idea of having sex with them was more important to me than God, nor did I commit any other sins as a result.
So is porn sin? In and of itself, I think not. Is it a good thing? Is it expedient? Probably not. At least it's not for me. (And Jason, warhorse, and others on here can attest to how damaging it was for them!) Are there bad and sinful things that are related to porn? Yeah, there are. Just like there are bad and sinful things related to many other aspects of our lives.
But, if watching porn in and of itself is a sin, I would like to see the specific scripture cited that says this. (Really, I would. I could use it when talking to people about this subject!!!) Sometimes it is just too easy for us to condemn people for certain activities just because we consider them bad for ourselves, and we are used to hearing that they are bad in our churches. We need to remember that if we condemn someone for something they are doing, we need to have solid scriptural support that the thing they are doing is actually a sin. We need more than just our own opinions or church tradition to tell someone they are sinning.
OK, end of devil's advocate game. But really, I do want to see the scripture. Not paraphrased in someones individual interpretation, but the actual scripture with verse and version reference!
