I note you picked the first paragraph of my response in post #42. How about addressing paragraph numbers 2 & 3. You may be able to answer your own question if you do so.

The question concerns the subjectivity of certain types of truths.
There is not much more that I can add concerning 2 and 3, both of which seem to support the subjective nature of the truth that is involved here. I don;t know if it makes too much sense to continue on it, but if you insist, here it is again:
Torture and slavery were at one time allowed. Now they are not. This would point to the subjective nature of some moral norms or truths.
The whole Eastern Church was excommunicated in 1054 because they insisted that the HS proceeds from the Father, and this was mentioned in the bull of excommunication. However, before 500 AD, I thought that the Church did teach that the HS proceeds from the Father and so read an early version of the creed. However, the present teaching is that the HS proceeds from the Father and from the Son which is not accepted by the Eastern Orthodox Church. If there is no difference between the two, why then was it mentioned in the papal declaration of excommunication in 1054?
As far as the primary purpose of marriage is concerned: Again one does not equal two. One and two refer to different mathematical entities. Before Vatican II, there was one primary purpose of marriage. That was the truth then. After Vatican II, there are two primary purposes of marriage. That is the truth now. so this also points to the subjective nature of the teaching.
I’ll give a different example now, illustrating the subjective nature of moral norms, since the above was repetitious. Before Vatican II, the norm was for decent language. However, after Vatian II, we see the appearance of lewd novels written by the Catholic priest, Father Greeley. They contain a lot of cussing and swearing, which was not the moral norm before Vatican II. And they contain certain profane expletives such as the exclamation: Jaysus. When someone gets emotional or such, the character will shout out “Jaysus”. Now although this may not technically be the use of the Holy Name of the Son of God in vain, since one or two letters have been changed, it is certainly pretty close to it, and it is not in the spirit of the Commandment. This was not allowed before Vatican II, but now, after Vatican II, I don’t see where his bishop has raised any objection. So this indicates that whether it is right or wrong to use this type of language and profanity has changed.
