Christ taught certain laws regarding how we are to conduct ourselves as Christians in this world. However, those are not the laws that levy eternal condemnation. Eternal condemnation is determined based on the following:
[Jhn 3:19-21 KJV]
19 And this is the condemnation, that light is come into the world, and men loved darkness rather than light, because their deeds were evil.
20 For every one that doeth evil hateth the light, neither cometh to the light, lest his deeds should be reproved.
21 But he that doeth truth cometh to the light, that his deeds may be made manifest, that they are wrought in God.
Christ is that light. Those not elected/saved, hate the light (Christ), because natural man loves and trusts only in his own deeds for salvation, thus rejecting God's mercy and grace through Christ. Therefore, the sin that brings eternal condemnation, is the hatred of Jesus Christ alone as the Savior.

They called him "Rabbi."
The Gospels are so beautiful in what it teaches, we too easily miss that what Jesus taught was to Israel,
and about how the Jews should have been living at that time!
It was the Apostle Paul that later on God raised up to teach all believers how all of God's children should walk spiritually.
Legalism appeals to the thick headed.
