Be Carefull Who You Say Goodbye To

Patrick Mead came by and had something interesting to say concerning my post on the word etymology of “goodbye”.

“In Shakespeare's day it had already shortened to "God bye you" and appears in a few of his plays that way. BTW, when JW's or others who deny Jesus equality with God come to my doorpost, that is why I do not say "Goodbye" to them when we are done speaking. The scripture says not to bring the deniers into your home or wish them God speed.”
Patrick Mead

I went and read the verses he left me on the subject and I thought I would post a couple of versions here, plus some information on what Godspeed means.

9 Whosoever transgresseth, and abideth not in the doctrine of Christ, hath not God. He that abideth in the doctrine of Christ, he hath both the Father and the Son.
10 If there come any unto you, and bring not this doctrine, receive him not into your house, neither bid him God speed:
11 For he that biddeth him God speed is partaker of his evil deeds.
2 John 1: 9-11 KJV

9 Anyone who runs on ahead [of God] and does not abide in the doctrine of Christ [who is not content with what He taught] does not have God; but he who continues to live in the doctrine (teaching) of Christ [does have God], he has both the Father and the Son.
10 If anyone comes to you and does not bring this doctrine [is disloyal to what Jesus Christ taught], do not receive him [do not accept him, do not welcome or admit him] into [your] house or bid him Godspeed or give him any encouragement.
11 For he who wishes him success [who encourages him, wishing him Godspeed] is a partaker in his evil doings
2 John 1: 9-11 Amplified

Godspeed
NOUN: Success or good fortune.
ETYMOLOGY: From Middle English God spede (you), may God prosper (you) : God, god; see god + spede, third person sing. present subjunctive of speden, to prosper (from Old English spdan, from spd, success; see speed).
The American Heritage® Dictionary of the English Language: Fourth Edition. 2000

“In the modern world, speed has come to simply mean a rate of movement (e.g. high speed, miles per hour, meters per second etc.), but the English (derived from the Anglo-Saxon) origin of the word meant not velocity, but to thrive, or to prosper. The term God speed, used by some translations of the Holy Scriptures, is a contraction of the saying, "I wish that God may speed you," or in today's terminology, "I wish that God may bless you with success." Both specific uses of "God speed" found in the King James Version have nothing to do with physical motion.”

I found What he had to say enlightening as I have never heard this before. What do you think?
