Judaizing Heresy?

Rit, i think that luther is right to make parallels. But can we make an exact equation? Rid says there are similar errors in the judaizing heresy of rome and colossians. Riht: What's going on with th judaizers is, what they're doing is essentially going back to the old covenant. And if you are trying to be saved by right, the type and shadow, rather than the fulfilment, now you've fallen into very serious error.
