...should become more like Him.Those who go to church to come to know the character of Jesus Christ,...
As I said, even the most devout and sincere religious believers often disagree; I've seen it happen THOUSANDS of times in my own experiences and surely we know that occurs an unfathomable number of times within the history of mankind....probably found it offensive that the pastor would instead use the opportunity to promote his personal views on homosexuality.
So be it.
In general, I see Jesus Christ as possessing certain characteristics. Many speaking out the way(s) they do on homosexuals and homosexuality, don't strike me as being particularly emulative of Jesus Christ.
People are going to disagree on religion; which is exactly why we should not seek to create or enforce laws from the same. If we ever do, say goodbye to true freedoms and liberties.
