"Natural Laws" or the "Laws of Science" are beyond man. They rest solely in God's hands.
A study of the Philosophy of Science will reveal this. Man's approach to Science is pragmatic at best. We are limited by our intellect, powers of observation, personal biases, and much more.
The fact that there is no absolute agreement on what Science actually is, is proof enough that we are in need of supernatural guidance.
For instance, even though Shelton dedicated his entire life's work to hygienic therapy, and we can assume he was sincere and honest about his work, he could be wrong. You are taking his work on Faith. Your faith has been experimented with in your own life and that faith is bringing forth fruit in your life and the lives of others.
This same method can be applied to religion.
Regarding dogmatism, should someone still insist that the earth is flat, would you be willing to dogmatically oppose that supposition? I would think so. And there would be nothing wrong with that.
Another hypothetical: If God visited you and told you to spread his message to all ends of the earth, would you not dogmatically do so? If he warned you of dire consequences to those who did not subscribe to said message, would you not even more passionately do his will?
