"We
know the Torah allows ______, because someone in a later book did that
and said it was ok." This is not a legitimate method of Torah exegesis.
While it can certainly be helpful to see how others understood certain
laws, their opinions or deeds alone do not determine what the Torah
says. After all, we know that Israel was dispersed and scattered for
their disobedience.
We should be testing these later prophets or later teachers by the Torah, rather than just assuming their accuracy and allowing their teachings to override what the Torah says. Later prophets are to be under the Torah, and they are to be tested by the Torah, rather than blindly believed. Being in the NK of the TNK or being in the NT does not automatically confirm them as valid. Canonization is only a tradition.
