"Religion that God our Father accepts as pure and faultless is this: to look after orphans and widows in their distress and to keep oneself from being polluted by the world." James 1:27
I think this ought to apply to the care for the unborn as well. For where is the father of unborn baby when he or she is being murdered? To take intentional action or to acquiesce in the murder of your child is to forfeit one's right to be considered a father.
