Thank you for your thoughtful responses. For a variety of reasons I don't want to address each response separately - out of respect for my parent.
20 years since DF'g with an aging guilt-laden, depressed person in pain and just out of surgery is complicated. Parent is mostly JW apologist but I softening the stance thru gentle and logical discussion.
Cofty's comments, I will share this with parent:
Is it worth trying to reason with parent that the prohibition on blood is based on a simple misunderstanding?, Did that w/ good success.
It was fine to eat unbled meat as long as the animal had not been killed - if it was found "already dead". Lev 11:38,39 Good to note.
Blood only had significance if a life had been taken therefore it does not apply to transusions. Excellent point. Must remember this.
I wish you well. Thank you
