As usual they provided an insightful etymology:
The belief system of the ancient Romans included spirits that were somewhere in between gods and humans and were thought to accompany each person through life as a protector. The Latin name for this spirit was "genius," which came from the verb "gignere," meaning "to beget." This sense of "attendant spirit" was first borrowed into English in the early 16th century. Part of such a spirit's role was to protect a person's moral character, and from that idea an extended sense developed in the 16th century meaning "an identifying character." In time, that meaning was extended to cover a special ability for doing something, and eventually "genius" acquired senses referring particularly to "very great intelligence" and "people of great intelligence."
There are a number of points from Scripture that comes to mind. Here are two:
First, Messiah is a genius in the first sense noted above: He had a single strongly marked capacity or aptitude. In fact He had a unique aptitude as savior and redeemer. Consider these verses:
For God did not send the Son into the world to judge the world, but that the world might be saved through Him. (John 3:17)
Much more then, having now been justified by His blood, we shall be saved from the wrath of God through Him. (Romans 5:9)
Second, we do have ministering spirits (Hebrews 1:14) in the form of angels (Matthew 18:10) who at a level between G-d and man (Hebrews 2:9). These messengers (aggelos in Greek means "messengers") are also referred to as "spirits" in the NASB and G-d is referred to as the Father of spirits (Hebrews 12:9) so the sense of gignere meaning "to beget" (above) applies as well. Scripture tells us that they are visible at times (Luke 1:12, John 20:12) but is generally silent about their explicit functions.
To our Father, the Father of all spirits, be the honor, glory, and power forever. Amen.
