Dues For Divorce

A cardinal said the Church cannot change its teaching on divorce.  OK.  It may be a bit of a high bar, but it is the bar the church has raised.  About half the marriages don't get over it.  Why not change the penalty?  Let the divorced and remarried who don't get annulments for whatever reason, still go to communion.  One is not the same as the other.  One is a teaching.  The other is a penalty.  Change the penalty.  I think it would be a subtitle of "Mercy."  Pope Francis is focused on mercy.  Mercy does not require laws or teachings to change.  It requires the heart of a hierarch to change.
