The Latin word “extra” is both an adverb and preposition. Depending on its use in a sentence, the word has different meanings. When used to describe spatial relations between objects, the word is translated as “beyond” or “outside of” (e.g., Beyond the creek is a tree; or, James is outside of the room). When used to describe abstract relations between concepts or intangible things, the word is commonly translated “without” (e.g., Without a method, it is difficult to teach). Within the phrase in question, extra is a preposition describing the abstract relationship of the Church to salvation. Considering the Latin nuances of the word, a proper translation would be, “Without the Church there is no salvation.” This translation more accurately reflects the doctrinal meaning of the phrase.
