It is the morality of acts of CP we are talking about (assuming given circumstances). They are moral acts in some circumstances and immoral in others.
This is true, although we have very different reasons for believing it.
I repeat, if the reasons given by the Popes are accepted, CP in the current era is immoral. The only debate is whether the arguments given are sound and can be accepted.
No. What can possibly make a misjudgment immoral instead of a mistake? It’s only if I believe it is wrong and do it that makes it wrong. If it is not per se immoral, as you have conceded, then
what makes it immoral for me to do it?
I’m not talking about those actual, reprehensible cases where an injustice is obviously committed. I’m talking about the difference between sin and error. What does it even mean to say “if the reasons given by the popes are accepted”? Accepted by whom? By me? You? The majority of Catholics? And what do you mean by “the popes”? Francis has not extended what JPII and BXVI said, he repudiated them. They are among those who failed to fully recognize man’s dignity. JPII explicitly said CP was admissible (even if under severe restraints), but Francis has said this is incorrect, it is inadmissible, and is not made acceptable even if necessary to provide security.
The morality of committing an act that is not intrinsically evil is determined almost entirely by one’s motivation for committing it. Again, at the extremes, nothing excuses doing something rash, or foolish, but a considered disagreement about whether the outcome of an act will or will not be harmful is not, and cannot be, a sin.
