Not exactly. Moses was not a charismatic speaker but backed up his words with a multitude of miracles, as did Jesus. There have been spectacular, undeniable miracles in the Catholic Church, that rise above the more frequent faked miracles, at least once every few decades.
You’d be amazed at how common miracles are. Why, the traveling salvation shows of the 1930s could heal people right there in the tent! They’d just rise up out of their wheelchairs and walk! Really! There were witnesses!
