I can see how there would be strong feelings about this; and the only way to counter it would be --- it seems to me --- strengthening the traditional meaning and reinforcing it constantly within your own community.
It seems to me, though, that ALL of Christianity is a reformulation of, or a competing interpretation of, Judaism. It would be hard to find an element that isn't. I was certainly taught (and rightly, I think) to "interpret" the whole body of Hebrew Scriptures "in the light of Christ."
Moreover, much of Protestantism is, it seems to me, a latching onto Catholic things to make them "mean something else." Again, this is so pervasive that to catalogue it adequately would take hundreds of pages.
There's no stopping it, and no use taking offense. The only response is in constantly reinforcing your own defining lines, in higher contrast.
