Very atstute observation. Let's take it one step further, given our knowledge of MormonISM.
Milt is a 'high priest' in LDS inc, literally. He has taken the oaths and sworn the lines to be a mormonISM 'Melchizadek High Priest'. He is also a bishop in LDS inc parlance, but that is not as significant as his high priest status.
What does it say about the character of a man who would take the oaths of high preist yet repudiate his own oaths for the expediance of political power? ... Yeah, Milt's mormonISM is an important aspect in considering his character. He's not just a flip-flopper, he's a duplicitous abomination: expedience, utilitarian decisions rule the mind of an unstable man like Milt is exposed to be.
I was under the impression that the Melchizedek priesthood was available to every little Mormon boy, even dark skinned ones after 1978. Being a Bishop is a lower office than that?
