Monica, it is difficult to be extremely clear.  We have to always deal in shades of gray.

Looking at two cases.  First, we have a serial adulterer (Newt Gingrich comes to mind) with two divorces, only civil services.  Then gets married in the Church.

Second, we have a woman, married in the Church, who was abused by her husband, gets a divorce and the gets remarried.

Who would the black and white clerics give Communion to, and why.  But who should be the one that ALL clerics realize needs the most spiritual help from the Reception?
