There are a lot of discussions and even debates in regards to whether Sarah Palin’s running for Vice President (and even possible Presidential office) is biblical or unbiblical. Some would say it is unbiblical to submit to any female leadership. Some would say it is perfectly OK to have female leadership in all walk of life, including church. As you can see there are all sorts of implications tied to this debate.
If you’re interested in some sound clarifications, I would recommend a recent four-part posts “Does Sarah Palin Present a Dilemma for Complementarians?” by the Council of Biblical Manhood and Womanhood.
