Fr. Iscara wrote that article in the early 1990's. It is at odds with Cekada's lonely viewpoint.
No where is it at odds with what Father Cekada wrote.
They were both educated & trained at the same Seminary, or did that escape you?
Father Iscara wrote this:
...it is morally justifiable to withhold antibiotics and artificial nutrition and hydration, as well as other forms of life-sustaining treatment, allowing the patient to die.28
To counter these conclusions, we are convinced that the provision of food and fluids is not simply —or strictly — "medical care," but the minimum care that must be provided for the sick, whatever their medical condition. All beings need food and water to live, but such nourishment by itself does not heal or cure disease. In consequence, to stop feeding the permanently unconscious patient is not to withdraw from the battle against illness, but simply to withhold the nourishment that sustains all life.
Moreover, to withdraw the artificial provision of food and fluids is not simply "to allow the patient to die" : what we are doing is not to cease a treatment against disease, but to withdraw what is essential to sustain the life of every human being, either healthy or ill. Death will happen, not because of the illness, but because of our omission to provide adequate nutrition and hydration.
In some very particular and extraordinary instances (as examples, in the case of a patient in a terminal condition to whom the artificial nutrition imposes a pain excessive in proportion to the very short span of life remaining, or in the case of an irreversibly demented patient who keeps tearing apart the feeding tubes and causing himself serious wounds, and who cannot be continually restrained) the inconveniences may become so burdensome that the artificial nutrition might be considered an Extraordinary, Non-obligatory means of preserving life.
