No bishop has signed off on it, at least not yet.
One can enter into a course of study (including for an M. Div.) without being a candidate for holy orders. One of the members of my parish got his M. Div. last year and has no intention of pursuing ordination.
In order for someone to pursue ordination in the Episcopal Church they have to first go though a discernment process within their parish; that process is not something that’s just an hour meeting and a signature, it takes some time. The Vestry of the Parish and it’s Rector or Vicar (there’s a difference) have to then vote to recommend the candidate to the Bishop. There’s another discernment process, and then the Bishop decides to sign off. Or, not.
What would be interesting here is to find out if the ex-Governor is now considered a member in good standing in an Episcopal parish anywhere, and then find out if he has entered the discernment process there. Where does he live? Is he going to church regularly there?
and hopefully that discernment process doesn’t go forward unless he has demonstrated relationship with the parish (has he served the people and the institution) and above all what is his voiced relationship with our Lord and savior, Jesus Christ.
