You are wrong on the Catholic Church stance. If death is imminent,and expected, you need not take extraordinary means.
However, witholding nutrition, and hydration to hasten death is not moral.
I watched my friend’s Dad undergo “comfort care”..He could have, without extraordinary means lived. Saline iV’s, morphine, and watching his lips become parched and the conjunctiva of his eyes stuck to his eyelids was horrible.
All I could do was tell him, “this is not what I would have chosen for you, but it wasn’t my choice, and sit by his bed side and pray.
