2 Timothy 3:14-17 But as for you, continue in what you have learned and have firmly believed, knowing from whom you learned it and how from childhood you have been acquainted with the sacred writings, which are able to make you wise for salvation through faith in Christ Jesus. All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness, that the man of God may be complete, equipped for every good work.
Matthew 4:4 But he answered, It is written,Man shall not live by bread alone, but by every word that comes from the mouth of God.
If the very Holy Spirit inspired, God breathed word of God is not authoritative and the standard by which all truth claims are to be measured is not adequate for the job, then certainly nothing that any men fabricated is.
Here is what the word Definition means: noun
1. the act of defining, or of making something definite, distinct, or clear: We need a better definition of her responsibilities.
2. the formal statement of the meaning or significance of a word, phrase, idiom, etc., as found in dictionaries. An online dictionary resource, such as Dictionary.com, can give users direct, immediate access to the definitions of a term, allowing them to compare definitions from various dictionaries and stay up to date with an ever-expanding vocabulary.
3. the condition of being definite, distinct, or clearly outlined: His biceps have great muscle definition.
4. Optics. sharpness of the image formed by an optical system.
5. Radio and Television. the accuracy of sound or picture reproduction.
That verse does not define the term. It does not set the limits or parameters of what SS is (or is not)
Prots whine constantly that Catholics don't have any idea of what SS is or that the "Catholic Answers": definition is wrong.
So show us the correct DEFINITION in the Bible.
P.S. Matthew 4:4 supports the Catholic position of Sacred Tradition, not SS.
