I don't preach but am wondering why it would be "difficult" to preach the truth.
Is there anything else worth preaching?
The main advantage homosexuals have in public discourse about their lifestyle is that normal people don't want to lay out exactly what is wrong with that mentality and sexual practice. Yes, it is hard to address it in a sermon in a meaningful way. We should be addressing the public health consequences of the sex and lifestyle. Knowing the consequences, it would be understood why it would be hateful for anyone to promote it or accept it. Priests and ministers have to be trained on how to address it without getting into the rated X gutter.
Because in an environment as liberal as Massachusetts, publicly affirming Bible truths will have real social and very possibly professional consequences. It would be like supporting the Vietnam War on an elite college campus in 1970. A fantastic way to simplify your social life.
