As the Lutheran (LCMS) of closest affiliation I know to Ms. Bachmann’s synod (WELS) can you shed light on whether this brouhaha about calling Roman Popes “the Antichrist” has any basis in contemporary devout Lutheran congregations? AFAIK, this was a position popular among many evangelical congregations of past centuries (not just Lutherans), but with the contemporary trend of the Roman church backing out of the role of playing the machine in secular governments and becoming less strident towards Christian congregations of other denominations, few evangelicals take this literal view seriously.
WELS has it on their website: Statement on the Antichrist.
They go through the history with Luther, various Synods views and then affirm as a current doctrinal view that the Roman Catholic Papacy is the antichrist.
That few evangelicals take it seriously shows where her church exists on the continuum.
Membership in a divisive church would only add to the Bachmann-candidate Obama parallels of holding a law degree, having no executive experience and no effective legislative record.
Considering the Pope is not just a religious leader but head of state, her beliefs in this regard could make diplomatic relations difficult. She may also support efforts to marginalize the Holy See at the UN.
However, that Lutherans regard the pope as the antichrist is a *doctrinal* view, not a political position, and it does not have anything to do with disqualifying a Lutheran from holding public office in the state.
