You see given his basic philosophy I don't see how he could tell anyone they were a sinner; he more likely said, if you are a sinner please change your ways you are hurting yourself most of all. Sin is subjective to each and every one of us. That's why he said do not judge others. That's for god to do. But of course the religion named after him had to change the meaning of much of what he purportedly said when they named him a god.
Subjectivity would be your example of a post. You presented nothing but personal opinion with the expectation that you would be believed because you believe. In other words your faith is subjective. The scriptures are OBJECTIVE in the fact they read the same for everyone. You suggested (subjectively) that sin is subjective and you can't be condemned if you don't condemn yourself.
Question? If these subjective statements are true........why the need for Christ Jesus? We will all simply judge ourselves and plead ignorance. Even modern jurisprudence declares this position as a logical fallacy. "Ignorance is no excuse".
The LAW/ORACLES contained in both the Old and New Testaments condemn no one. The purpose of a law is to define sin.....where there is no law there can be no sin possible....there is no sin in the animal kingdom because animals cannot choose between morality and immorality as defined in God's law.
Everyone is born into a world filled with sin.....because FREE WILL exists. Example: God was sorry that He even created man on earth because by majority men were choosing unrighteousness/evil over righteousness/good. ( Genesis 6:5-6) God could not have known how man would choose beforehand. No one is born a sinner....... Sin is the transgression of the LAW (1 John 3:4). All sin is "unrighteous" (1 John 5:17)
When sin is mentioned in scripture its always "your sins" or "thy sins" Example Acts 3:19, 22:16). Man is judged by how he lived, by what he has done....not because he was born into sin .......he is judged in comparison to the words of the Christ, as it is the Christ that is our advocate that stands between our sin and God. (Matt. 12:48) On judgement day.......the BOOKS WILL BE OPEN. (Rev. 20:12)
Read be enlightened. A lesson from the Old Book, "The soul WHO SINS (not was born with sin) shall die. The son shall not bear the guilt of the father, nor the father the guilt of the son. The righteousness of the righteous shall be upon himself, and the wickedness of the wicked upon himself." -- Ez. 18:20
