“[T]he reason he first said ‘The scribes and pharisees sit upon the chair of Moses’ was so that what he then added, viz., ‘Do everything and observe everything they tell you,’ [Matthew xxiii, 2-3] might be understood to apply to those things which pertain to that chair. However, things which are contrary to the faith or to good morals do not pertain to that chair.” (St. Thomas Aquinas, Quodlibet 3.4.2)
