I pretty much recognize you and soothing Dave as experts on the RCC. Is there anyway that he could receive an annulment? How about a civil divorce, could an annulment likely be granted due to grounds of a lack of consortium?
There has to be something hidden somewhere in Canon Law that has enough room to at least take away this part of his desire to see Teri dead.
JosephW - Have you read any of my responses to you? There is NO WAY he will get married in the Church. None. Canon law would forbid it under the circumstances. Period. End of story.
At least not for a remarriage with this woman, considering the relevant canon law posted above. Maybe he could get remarried to someone else.
The two essential components for a valid marriage are that at the time of marriage the spouses must intend a lifelong commitment and openness to children. It certainly seems possible that he didn't intend a lifelong commitment at the time of the marriage.
