4.3 Dogma
Article 105 - Orthodoxy
Canon 4170 (link)
The strength of Orthodoxy as a dogmatic principle is that not only does the concept establishes the claim by a particular Religion or Cult that their practices are superior, but that all other practices are abnormal and do not follow accepted custom and tradition. As Custom is traditionally seen as a basis for justifying a particular law, a practice is not orthodox is implied by such terminology as being “unlawful”.
