I am going to revise this OP every few days so it will eventually be an exhaustive list that orthodox Christians can use for this subject.
1) Conflation of the Biblical terms of Nomos (Mosaic Law) and Entoli (personal commands of Jesus and other people in the Greek) the New Testament differentiates these things with different terms but Seventh day Adventist conflate them with verses like
There are many verses where "entoli" refers to the commandments of God:
In Matthew 5:17-19, it refers to the Law and the Prophets.
In Matthew 15:3 and 15:6, it refers to the commandments of God.
In Matthew 19:17, the Ten Commandments are examples of what it is referring to.
In Matthew 22:36-40, it refers to the Mosaic Law.
In Mark 7:8 and 7:9, it refers to the commandments of God.
In Mark 10:5, it refers to the Mosaic Law.
In Mark 10:19, it refers to the Ten Commandments.
In Mark 12:28-31, it refers to the Mosai Law.
I could go on, but so far there is not a single example in Matthew or Mark where "entoli" is used to distinguish between the personal commands of Jesus and the Mosaic Law. Christ set a sinless example of how to walk in obedience to the Law of Moses, including keeping the Sabbath holy, he did not hypocritically preach something other than what he practiced, and as his followers we are told to follow his example (1 Peter 2:21-22) and that those who are in Christ are obligated to walk in the same way he walked (1 John 2:6)
John 14:15-31
15 If ye love me, keep my commandments.
The way to love the Father is identical to the way to love the Son and there are many verses in both the OT and the NT that show that God's commandments are His instructions for how to do that, so again I don't see any grounds for thinking that this verse is referring to something else. In John 15:10, Jesus used a parallel statement to equate us keeping his entoli with him keeping the entoli of the Father, and again if his entail were something different, then that would mean that he hypocritically preached something other than what he practiced, and that he wanted us to only follow what he said, but to not follow his example, which also would negate the whole rabbi/disciple relationship.
A number of Jesus's commandments go beyond the Mosaic Law requiring people to be more proactive when it comes to doing things like loving their neighbor or avoiding the enticement of sin. On the other hand, I believe that Jesus commands are much benevolent when it comes to some of the exhausting minutiae of the Law, and the halacha around it. I believe they get at the real spirit of the law that Love of God and Love of man is the summation of the Law.
In Galatians 4:4, Jesus was born under the law, so he was obligated to obey it, and he was sinless, so he never broke it, which includes never breaking Deuteronomy 4:2, which prohibits adding to or subtracting from the law, so he did not God beyond the Mosaic Law, and for you to suggest that he did is to claim that he sinned and to deny that he is our Savior. Teaching people to be more proactive in their obedience to the Mosaic Law is not going beyond the Mosaic Law. Jesus was not in disagreement with the Father about which laws we should follow, so he did not modify the Mosaic Law, though he did teach how to correctly obey it as it was originally intended. A sum is inclusive of all of its parts, so a summation of the Mosaic Law does not modify it, but teaches about what it is essentially about how to do. For example, when we keep the Sabbath holy, we are expressing our love for God's holiness, but when someone does not do that, they are expressing that they do not love that aspect of who God is.
