I think that one mainstream scholoarly view makes sense, that the answer to the question of this thread is found in 2:11: the "name that is above every name" is "κυριος", "Lord", i.e. the concrete name of God. I think the idea is, that "Lord" in 2:11 carries the same doubleness as in the LXX. A designation of authority and at the same time a proper name. A whole bunch of conceptions are tied together here, because the very
concept of 'name' includes wide spectrum of meaning. Apart from being a simple calling (or writing) sound that refers to a person it also means 1) reputation and 2) authority. The reputation of God, as with any 'patron' in the honor/shame society of the Mediterranean world, is his honor, or 'glory'. Consider also the English term 'renown' from the French word for 'name'. God's 'name' is tightly connected with his 'glory' as well as his deeds. Those are typically in the OT either 1) creation with the subduing of the disorder and chaos and the life-giving sustaining of creation, or 2) the salvation of Israel out of Egypt and into the promised land. For the Christians, God's "mighty deeds" now was the same two ideas converged into one: the raising of Jesus from the dead, truly a mighty deed.
Also one's name carries one's
authority, as in the expression 'in the name of the law' or 'in the name of the king' or one's signature on a document. Invoking the name of a deity means invoking his or her power. Using the name of a person of deity means wielding the authority of that person or deity, in principle at least. A centurion can act in the name of Rome, or in the name of the emperor, i.e. he uses power by Rome's authority. Similarly, Jesus can use power with God's authority, but that is the life-giving power of the creator, most often called "δυναμις". For this very comparison see Matt 8. That God "bestowed" (χαριζομαι) upon Jesus the "name that is above every name" is thus a close parallel to "God highly exalted him". It is almost nothing more than a parallellism in 2:9. I think that "bestowed upon him the name above every name" can understood as "bestowed upon him the authority above every authority". It is significant that he is not merely 'given' a name, which would be διδωμαι, but "bestowed" (χαριζομαι).
So this expresses the full way that Jesus can now act in the name of God, he is his plenipotentiary, he has been given authority from God.
Having God's name is also an expression of sonship, a family name, or 'adoption'. He is the heir to the rulership of God. So the glory is to God "the father", Phil 2:11.
Cf. Heb 1:
Heb. 1,1 ¶ Long ago God spoke to our ancestors in many and various ways by the prophets,
Heb. 1,2 but in these last days he has spoken to us by a Son, whom he appointed heir of all things, through whom he also created the worlds.
Heb. 1,3 He is the reflection of God’s glory and the exact imprint of God’s very being, and he sustains all things by his powerful word. When he had made purification for sins, he sat down at the right hand of the Majesty on high,
Heb. 1,4 having become as much superior to angels as the name he has inherited is more excellent than theirs.
Heb. 1,5 ¶ For to which of the angels did God ever say,
“You are my Son;
today I have begotten you”?
Or again,
“I will be his Father,
and he will be my Son”?
Heb. 1,6 And again, when he brings the firstborn into the world, he says,
“Let all God’s angels worship him.”
Heb. 1,7 Of the angels he says, ... etc.
Jesus' sonship means he has "inherited" God's name, like the son of a ruler inherits the rulership through the family name. Cf. also Matt 28:
And Jesus came and said to them, “All authority in heaven and on earth has been given to me.
Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit,
and teaching them to obey everything that I have commanded you. And remember, I am with you always, to the end of the age.”
(Matt 28:18-20)
This "name of the Father and of the Son and of the Holy Spirit" is not a concrete name, it means "authority". The father, son and spirit are all one, in the same way as a family, the Christian spiritual family, but it is Jesus who has the authority.
So even though Jesus has his own name, Jesus, he has been bestowed with the authority of God by receiving his name in the meaning of authority. I think it means that Jesus has been bestowed various central divine attributes of God, YHWH, that was connected with the very name of YHWH. I think what is meant in Phil 2:9-11 is that the divine power that recided also in the sacred name of God, the tetragrammaton, was transferred to the
person of Jesus. The
person of Jesus has received authority of the power that recided in the
name YHWH. Which means that Jesus' own name now invokes the power of God that previously was invoked by God's own name, YHWH.
So when the Christians, in turn, invoke Jesus' name, they can use his authority (act in the name of Jesus), and that is the authority to use or channel the power of God the creator, his life-giving power, the δυναμις. But only if one is "of Christ" or "in Christ" can one wield Jesus' divine authority, cf. Acts 19:11-20.
