I recently heard a presentation from a Dati Leumi Rav and posek [in a very sensitive area of Halacha] that began well but ended in a theological quagmire. He proposed that the authority of the Torah is predicated on its alignment with human morality rather than its status as Divine Truth. He argued that if the Torah issued a command that violated our moral sensibilities—like punching an innocent person—we would ignore it.
The problem is that the Torah contains many "hard" commandments, such as the laws regarding Amalek and the Shiva Ammamin [which amounts to much more than a mere punch in the face], that challenge modern ethical frameworks. To suggest we only follow what we deem "good" is to make man the judge of God [and "good" for that matter].
Furthermore, he asserted that the Rabbis "changed" the law of Ayin Tachas Ayin because it wasn't "good." This undermines the belief [as per Rambam] that the oral interpretation (monetary payment) was given at Sinai [or at least derived from pesukim or svara but certainly not that the Rabbis purposely changed the true intent of the pasuk]. By suggesting that the Chachomim "edited" the Torah to fit evolving sensibilities, he is treading on the territory of kefirah. [Sadly, nobody challenged him].
Wearing a kippah seruga doesn't cost a Rabbi his credibility, but preaching what amounts to kefirah (heresy) certainly does.
