FOURTH ARTICLE: WHETHER WE MAY HAVE CONTRARY OPINIONS ABOUT THE NOTIONS

This article was written because the Greeks held other opinions about common spiration when they denied the Filioque.

St. Thomas replies that it is lawful to have other opinions about the divine notions provided that no conclusions are reached contrary to the faith proposed by the Church. With regard to the Filioque, we shall learn the doctrine of the Church when we treat in particular of the Holy Ghost as He proceeds from the Father and the Son. This doctrine was defined as early as 381 in the First Council of Constantinople.[373] This concludes the questions concerning the divine persons in common.
