I attended an LDS Sunday service with a mormon relative who had come to visit.
It was a business meeting and there was no sermon to speak of, just church business. No worship at all. Perhaps they get that in a different service. I don’t know. But I do know I did not feel the presence of the Holy Spirt which I have felt in my own church and in some other churches and often in denominations other than my own. A Christian is well aware of the presence of the Holy Spirt in a church that is based on scripture.
When I was living with my mormon family, I went to ward with them for nearly a year (until I couldn’t take it any longer), there never was worship as Christians understand it.
There was their version of communion, which made me sick to my stomach.
You are correct, there is no feeling of the Holy Spirit as Christians know it, even God Almighty is not there.
