And what might, depending on context, be analogous to the two words “kill” or “murder” in the case of adultery?
Thomas I just went to great lengths to explain this to you.
Its simply a matter of the Church’s definition of “adultery”.
You either accept the definition or you don’t. It isn’t negotiable.
If you do not accept the definition then you end in solipsism because no one else here speaks your language.
And the definition is very clear. Adultery simply describes body mechanics to put it bluntly.
You sleepwalk to the lonely widow next door and remember nothing…its still adultery.
You are King Oedipus before he discovered he married his mother…its still adultery (and incest to boot).
With full consent and understanding and charm you seduce a co-worker…that is adultery.
Yet only the last is likely mortal (the others would not even be venial)…but only you can know that because I am not in your head.
But I can still judge that in all three cases there was “adultery” because it is objective and scientifically accessible. So this definition of adultery is clearly like “killing”. It may be done sleepwalking, it may be done thinking it is not really killing (someone replaced the blank in my gun with a live round), or it may be purposely understood and intended. In all cases it is still called “killing”.
But “murder” is always a mortal sin because most of us understand it to mean freely and knowingly choosing to kill unjustly. In other words the very definition describes all three components of a mortal sin. “Adultery” does not, the definition only includes one component - the “matter”.
If you don’t accept this definition of adultery that is fine.
But the consequence is that no one can answer your questions because they simply don’t make sense to us given the different definition that we are following.
Let’s be honest. You are attempting to maintain that at least some Catholics in an irregular union who persist in sexual relations, even in light of accompanied discernment, should be permitted to receive Holy Communion. Is this not correct?
No. I am simply trying to establish the basis of a rational conversation with you

.
But that cannot get off the ground if we work from logically contradictory starting definitions over how “adultery” is defined by Catholics.
That is perhaps why you keep saying that people don’t understand you or why you don’t find arguments persuasive, or why you keep seeing “strawman” arguments or why you at times seem to think I am trying to be intentionally mendacious or difficult.
