The Basis of Communication

A name is not only an internal element of an ontology - of being aware that a thing exists even if you do not see it in front of you at the moment - but it is also a means of communication:

Exod 33:17
17 And the LORD said unto Moses, I will do this thing also that thou hast spoken: for thou hast found grace in my sight, and I know thee by name.
(KJV)

A stranger is someone who’s name we do not know. It is only after we know the stranger’s name that we can really communicate with him (or her.):

Exod 33:17-19
17 And the LORD said unto Moses, I will do this thing also that thou hast spoken: for thou hast found grace in my sight, and I know thee by name.
18 And he said, I beseech thee, shew me thy glory.
19 And he said, I will make all my goodness pass before thee, and I will proclaim the name of the LORD before thee; and will be gracious to whom I will be gracious, and will shew mercy on whom I will shew mercy.
(KJV)

John 10:1-5
1 Verily, verily, I say unto you, He that entereth not by the door into the sheepfold, but climbeth up some other way, the same is a thief and a robber.
2 But he that entereth in by the door is the shepherd of the sheep.
3 To him the porter openeth; and the sheep hear his voice: and he calleth his own sheep by name, and leadeth them out.
4 And when he putteth forth his own sheep, he goeth before them, and the sheep follow him: for they know his voice.
5 And a stranger will they not follow, but will flee from him: for they know not the voice of strangers.
(KJV)

John 17:6
6 I have manifested thy name unto the men which thou gavest me out of the world: thine they were, and thou gavest them me; and they have kept thy word.
(KJV)

John 17:26
26 And I have declared unto them thy name, and will declare it: that the love wherewith thou hast loved me may be in them, and I in them.
(KJV)

But there is also dis-communication and miscommunication in a name.

Exod 23:13
13 And in all things that I have said unto you be circumspect: and make no mention of the name of other gods, neither let it be heard out of thy mouth.
(KJV)

John 5:43
43 I am come in my Father's name, and ye receive me not: if another shall come in his own name, him ye will receive.
(KJV)

And in a Name there is ultimate communication:

Acts 4:12
12 Neither is there salvation in any other: for there is none other name under heaven given among men, whereby we must be saved.
(KJV)
