That's pathetic. Would like to point out exact how these principles are the same? In actuality, the LDS use the exact same method to prove their interpretations are correct as the Roman Catholic Church. Would you like to see the evidence?
"In the Latin West, it is usually held that the Spirit proceeds "from the Father and from the Son"; and the word filioque ("and from the Son) has been added to the Latin text of the Creed. Orthodoxy not only regards the filioque as an unauthorized addition-for it was inserted into the Creed without the consent of the Christian East-but it also considers that the doctrine of the "double procession", as commonly expounded, is theologically inexact and spiritually harmful."
