You have a source for all that? Preferably not a dedicated anti-Mormon site. I am honestly interested to read for myself and see if what you wrote it true. My impression is that he is a typical politician who uses his faith to get elected while being a functional atheist in practice. But I am willing to learn.
Mitt is a validated Temple Mormon, they face an interview every two years and are verified to comply with the requirements of the heaviest devotion to Mormonism, including turning in a minimum of 10% of their income to the church.
They are reissued ID every year that they qualify in this level of devotion, this entitles them to enter the Temples, and be a member of the secretive Temple operations for instance, normal Mormons cannot enter them, and were unable to witness Mitt’s temple marriage for example, (as were Ann’s parents).
Mitt has been a Bishop, and the Stake President over all the Bishops of his region, his duties and powers included, awarding and denying Temple status which is the path to becoming a God, and excommunications of Mormons deviating from the religion (in Mormonism, you are either in, or out).
