Hi, ive read in much older threads here the debate on whether the supposed new Covenant by Jesus that overwrites the old is valid.

Ive seen that Paul advocates this in Romans, and this is really the only place that advocates this.

Ive seen numerous Gospel passages from Matthew and John seemingly supporting upholding the Old Covenant.

"“For truly, I say to you, till heaven and earth pass away, not an iota, not a dot, will pass the law until all is accomplished. Whoever then relaxes one of the least of these commandments and teaches men so, shall be called least in the kingdom of heaven; but he who does them and teaches them shall be called great in the kingdom of heaven.”
-Matthew 5:18-19

John admonishes (i think) the Pharisees for not upholding the OT in John 1:17

I have wondered about Luke, there is a very explicit passage

""Do not think that I have come to abolish the law or the prophets. I have come not to abolish but to fulfill. Amen, I say to you, until heaven and earth pass away, not the smallest part or the smallest part of a letter will pass from the law, until all things have taken place."
-Luke 16:17

Which suggests that the old covenant is binding forever (or at least till the earth passes away).

However in the last supper, in Luke i believe, Jesus says that he is making a new covenant with his blood to his Disciples.

What does this mean, did Luke contradict itself?

I realise there is probably tons of old threads on the Covenants being repealled, but i could not find anything about this verse in Luke.
