Judge not, that ye be not judged.
I think that many liberal Christians/non-Christians have taken the interpretation of the meaning of this verse too far and have gone so far as to say things like, "No one should ever say that homosexual behavior is sinful, even if the Bible says it is, because to be saying that it is [even if the person saying it means it in general terms] judging people!" It was Jesus that said that phrase, but he in John 8:11 told Mary Magdaline "go, and sin no more!" In that verse, he was clearly referring to the prostitution she was engaging in and he was making a definite statement that prostitution was wrong.
Liberal Christians/non-Christians talk about how Jesus spent time with prostitutes and others, but they ignore that they largely stopped their practices which were considered sinful while in ministry with him and instead are trying to shut down any argument about what the Bible does say (and there is a lot of question about what it does say) about certain behavior being sinful or not, and simply want to stop their ears and go "Nyaa nyaa nyaa! You're judging!" I think they also forget another passage in the Bible when they do this (2 Timothy 3:16-17):
All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness: That the man of God may be perfect, throughly furnished unto all good works.Notice "for correction" and "for instruction is righteousness"? The Bible itself is stating that simply labeling a behavior as sinful (provided you can back it up with Scripture) is not wrong at all.
I am not a Christian and so I am not going to be part of the debate about whether this or that is sinful according to the Bible, but I do want to point out what seems to me to be a dishonest argument by the liberal Christians/non-Christians twisting the Bible around to shut up the pastors in the churches, so that they may not again argue that certain behaviors are sinful, because the liberal Christians/non-Christians do not want them labelled as such. It is disappointing to hear these arguments pushed around by otherwise smart people.
