The analogies about new cloth and new wine may have some twists to them ...
New cloth is probably better than old cloth.
But by contrast, old wine is better than new.
In the corresponding phrases in Luke (chapter 5:36-39) Jesus goes ahead to say that you're probably going to say "the old wine is better."
So he seems to be saying if for you the old way is like old wine, better than new, then that's fine, go with that.
But for some people, the new way is like new cloth, better than old, so that's what he's working on.
