I don't think he meant "moral ideal." What Hitler was referring to was the clergy's ceremonial leadership position that impressed him so much as a child. Later, as dictator, he constantly attempted to produce spectacles and events that would emulate and replace religious ceremonies in the life of the German people. And of course, the person at the center of these new rites would be - who else but Adolf himself?
An illuminating passage from his "Mein Kampf" describes his viewpoint on religion (and science for that matter)
The political leader should not estimate the worth of a religion by taking some of its shortcomings into account, but he should ask himself whether there be any practical substitute in a view which is demonstrably better. Until such a substitute be available only fools and criminals would think of abolishing the existing religion. Undoubtedly no small amount of blame for the present unsatisfactory religious situation must be attributed to those who have encumbered the ideal of religion with purely material accessories and have thus given rise to an utterly futile conflict between religion and science. In this conflict victory will nearly always be on the side of science, even though after a bitter struggle, while religion will suffer heavily in the eyes of those who cannot penetrate beneath the mere superficial aspects of science.
