One Doctors diagnosis is just as good a another ones, or even some one that has no medical training at all. If they disagree it is irrelevant.
If they adopt each others diagnosis they are merely throwing their lot with a whole bunch of other people.
After all you treat a hernia the exact same way you would coronary blockage, they are both surgery. Or treat Polio the same way you would diabetes. They are both diseases.
Please keep talking.
There's only one Holy Spirit which leads and guides believers, so your analogy doesn't work, except for those who listen to men.
