I feel you on this one. I look at world in a whole entirely different aspect because of my daughter dying in my arms at the front door of the emergency room. I also disagrees with homosexuality because God disagrees with it. After going through this trauma in my life, I realize that you never know the day or the hour when you are going to die. I had to check myself to make sure I am doing what God want me to do. I don't treat anyone differently because of what they choose in life. There are pastors being voted in who are liars,adultery,stealing money, etc., Would you like for me to keep going? My advice to you is leave there but who say the next pastor you go to is not a homosexual.
By the way, how do you know this pastor is gay?
