I appreciate your candor. Your position is exactly that which traditionalists ascribe to neoCatholics.
Now, if you please, would you care citing a Doctor or Father of the Church who shared this characteristicly neoCatholic disposition?
Maybe you ought to define what you mean by extrinsic tradition. I take it to mean trappings, and customs, and the like which have no real bearing on doctrine.
What do you take it to mean?
