When you say not according to God or Jesus but according to 'Jewish law' do you mean some document Jews authored and not God? so then "Not scripture"? Not "The Word of God"??
2 Tim 3:15 "
all scripture is given by inspiration from God"
Heb 3 "
The Holy Spirit said ..." referencing text in the OT.
Are you talking about "Jewish tradition" as in Mark 7:6-13???
Jesus often corrected Jewish tradition as we see in Mark 7.
agreed.
And often violated the Law in their idea of tradition as Christ points out in Mark 7.
Mark 7:
6 But He said to them, “Rightly did Isaiah prophesy about you hypocrites, as it is written:
‘This people honors Me with their lips,
But their heart is far away from Me.
7 And in vain do they worship Me,
Teaching as doctrines the commandments of men.’
8 Neglecting the commandment of God, you hold to the tradition of men.”
9 He was also saying to them, “You are experts at setting aside the commandment of God in order to keep your tradition. 10 For Moses said, ‘Honor your father and your mother’; and, ‘The one who speaks evil of father or mother, is certainly to be put to death’; 11 but you say, ‘If a person says to his father or his mother, whatever I have that would help you is Corban (that is, given to God),’ 12 you no longer allow him to do anything for his father or his mother; 13 thereby invalidating the word of God by your tradition which you have handed down; and you do many things such as that.”
=============================
But that is not what we see here -
The New Covenant is found in
Jer 31:31-34 and includes the Law of God spoken at Sinai - and known to Jeremiah and his readers as the Law of God -- according to the text
.
Matt 28:19 - Jesus tells His disciples to go and teach everything that He taught them - which is why we have gospel accounts of Jesus' teaching and practice. As you admit - His teaching and practice was to affirm scripture - not reject it.
