For we have not an high priest which cannot be touched with the feeling of our infirmities; but was in all points tempted like as we are, yet without sin.
Yet in the next chapter, we find:
Hebrews 5:8-9 wrote:Though he were a Son, yet learned he obedience by the things which he suffered; And being made perfect, he became the author of eternal salvation unto all them that obey him;
And Jesus himself saying:
Matthew 19:15 wrote:And he said unto him, Why callest thou me good? there is none good but one, that is, God
Granted, this is a very cursory search for verses that mention keywords. I'd like to hear what you have to say about how this belief came about, and what scriptural basis there is for it. Quoting LDS scripture is okay, I suppose, but since this is not uniquely an LDS belief, I'm not sure how much it would help. Bear in mind that I am aware of Old Testament era calls for the sacrifice of an animal without spot or blemish and how that allegedly foreshadows Christ, but I am also aware that Jesus' followers saw him as the fulfillment of such scriptures and therefore, in my mind, such references only bolster the argument that his followers possibly began to retroactively apply such attributes to him.
