As to Count VI.
VI. Moral principles and moral truths contained in divine revelation and in the natural law do not include negative prohibitions that absolutely forbid particular kinds of action, inasmuch as these are always gravely unlawful on account of their object.
– Open Letter to Bishops of the Catholic Church, Easter Week, 2019
In FUNDAMENTALS OF CATHOLIC DOGMA, there are no De fide dogmas that are relevant to this count.
Now [if the proposition has been understood correctly],
CCC 1789 Some rules apply in every case:
– One may never do evil so that good may result from it;
Therefore, Count VI. is a false proposition (propositio falsa), a proposition contrary to a dogmatic fact which in this case is ‘there are acts which are evil in themselves regardless of their intended outcome’.
