Thank you, everyone, for your replies to my post. I truly appreciate it. This has given me some good info to think on.
Just to give some more back story, I am fully expecting my son to not want a blessing. He really dislikes the church. He thinks that it's most likely not true and said that even if it is true then he doesn't want to live with God because God does things that he is very strongly opposed to (assuming that what the church teaches matches reality). The biggest one is that the church teaches this (this is a direct quote):
This means that someone who is deeply in love with someone of the same gender and chooses to marry that person and they live a life full of joy and do good things is not only sinning (because they acted on their feelings of same gender attraction) but they can never be exalted unless they split up with the person they love so deeply. My son finds this deeply troubling and repulsive. There are other things like this that trouble my son. He has been consuming content that is against the church and he plans to remove his name from the church's records the second he turns 18. So hopefully you have a better idea of my son's position. This is what makes me wonder if it's even appropriate to offer a blessing in the first place if he is of this mindset and has no faith in Jesus, nor a desire to have faith in Jesus.
