I would be curious to hear what the exact message was. If it was, “homosexuals will surely burn in Hell for all eternity”, I may have disapproved as well.
If the message was, “engaging in homosexual activity is a sinful, disordered way to behave and is a life that is not in line with God’s plan. Similar to greed, gluttony, fear, jealousy, and pride...sexual immorality in the form of lust, adultry and homosexuality should be repented of and guidance should be found in Christ.”....then I would be fully in favor of it.
Many churches post MP3s of the sermons, His church might.
That's why Jesus taught bit by bit along His way, then took a full day and a night for His Sermon on the Mount!
Fortunately, we are blessed to have all His words God chose to give us in Holy Scriptures so we may have them with which to teach us and share (and preach, if so chosen) to others.
Currenly, the sins of greed, glutonny, fear, etc. are not sins being strongly pushed to our young in every aspect of life by the culture but it is the Big Lie of the "naturally, normalcy and even preferable sin of homosexuality."
