I think you misunderstand the nature of Christian Morality.
“You shall follow the law that is written on your hearts”. The Old Testament, the Covenant of Moses gave to Israel a Law written in Stone, and expounded upon by the High Priests. It was legalistic, and prohibitive. It was about obedience to that law.
The Christian Covenant has but 2 Laws:
- Love the Lord your God with All your Heart, All your Soul, and All your Strength.
- Love your neighbour as yourself.
The moral Law written on our hearts is, in Catholic Theology, referred to as “Natural Law”.
This is derived from looking at the world around us and what the Lord has revealed to us in His Creation, and it is further informed by what he has revealed to us in His Word.
The examples set in the Old Testament tell of a pedagogical period where the Lord was educating His People and bringing them to the point of the Coming of the Messiah.
We are no longer in that time.
When the church tells us that some act is Intrinsically Evil, it is with good cause and with direct attributable harm caused to the sinner, the victim of the sin, or to society as a whole.
If something is defined as a sin that is because it either causes harm, or has unmitigated and unreasonably high chance of causing harm. This could be to the sinner, a third party or to the broader society.
We have discussed one or two areas in detail in the past, but if my memory serves me correctly you have tended to directly reject our arguments about the direct or indirect harms caused or in some cases called significant harms “good”. There is a significant frame of reference issue causing part of this. You and I currently lack the ability to see certain issues from the same viewpoint or to consider some of the others views as valid. this causes severe difficulty in reaching any form of meaningful resolution to those discussions.
I hope and pray that the reason you are on this forum is that at some level you are truly open to learning and changing your views. I pray the Lord will work in your heart and lead you to His Grace.
On the topic of Obedience. the current teaching of the Catholic Church is clear that blind obedience does not mitigate ones culpability for committing a gravely immoral act. One is subject to the guidance of your own conscience, but that must be properly formed and informed.
