By the Catholic church or the scriptures???
Once you throw out the Church and Tradition, it becomes an anything goes free-for-all.
Where does scripture condemn Arianism, Macedonianism, Applinarianism, Semi-Arianism, or pretty much any other Christological or Trinitarian heresy in the book?
If the judgment of scripture alone matters and that of the Church or the Church Fathers is irrelevant, than what authority do you have to condemn the Jehovah’s Witnesses or any other group for that matter for how they read the Bible?
It seems to me to come down to a matter of taste otherwise.
