Authority

"They went to Capernaum, and when the Sabbath came, Jesus went into the synagogue and began to teach. The people were amazed at his teaching, because he taught them as one who had authority, not as the teachers of the law."

(Mark 1:21-22)

Authority: "The power to enforce laws, exact obedience, command, determine, or judge", from French, autorite, "book or quotation that settles an argument," (c. 1230), from
Author: "One who sets forth written statements," from Latin, autor, "father", "one who causes to grow," from Latin, augere, "to increase".

So, authority, at least in some vague etymological degree, means the power or quality of the father. ehhhhh
