Jesus did not say throw out the old, instead, what he did was simplify and refine all of the rules found in the Old Testament.
Basically, what Jesus says is "All of those rules really break down to two Great Commandments, Love GOD and love others as you love yourself."
Einstein, like Jesus, looked at the existing world, then took all the various rules and theories and reduced them, simplified them into the basics.

Jesus did not want us to forget all that came before but he did want us to go directly to the important parts, the essentials.
Love GOD, and loves others as you love yourself.
It really is that simple.
