“I am not sure I have,” Trump said when asked if he’d ever asked God for forgiveness. “I just go on and try to do a better job from there. I don’t think so,” he said. “I think if I do something wrong, I think, I just try and make it right. I don’t bring God into that picture. I don’t.”

And if you read further you’ll see that he talks about communion and that that is a form of asking forgiveness.
So, the bottom line is that at no point does he ever say “never”.
