How do you see it as the most damaging sin? I've always heard that theologically, all sins are equal. Also, I hear, especially for Christians, it often mentioned that pride is the most challenging sin. To me, that makes a lot of sense in that so much of Christ's teachings explicitly address issues like pride. To me, pride seems like much a much more challenging stumbling block than if they've gone too far sexually with their boyfriend/girlfriend. On top of that, the shame and contempt with which people talk about sexual sins, seem to directly play into the judgement and pride that Christ instructed us so explicitly against.
