"Alone" or "Only" (How They're Construed)

Nincsnevem insists that Isaiah 44:24 excludes any other being from sharing in the act of cosmos-creating except YHWH; he insists that no creature can share in creating, in part, because YHWH declares that he created "alone" without assistance from anyone else or so it seems. On the other hand, Jehovah's Witnesses maintain that one should not ignore the context of Isaiah 44:24.

Additionally, Paul Blowers documents examples where the Tertullian and the post-Nicenes, qualified Isaiah 44:24 in view of Proverbs 8:22-27 and Blowers demonstrates how they read the Isaianic verse: the pre-Nicenes and post-Nicenes applied Isaiah's words to the Father. At least the Fathers had one thing right. Yet one way I want to question Nincsnevem's line of thinking is by pointing to John 17:3, Matthew 24:36, 1 Timothy 6:16.

As we know, John 17:3 refers to Jesus' Father as the only true God. The adjective "only," which at times is also employed adverbially can normally exclude others from a group or situation in the way that "alone" might, but how do Trinitarians view the expression "only true God" in John 17:3? Do they take it to be exclusionary?

My experience is that they either attempt to include Jesus in the expression "only true God" since the verse concludes with mention of God's Son or they claim that the Father is the only true God in relation to false gods (see BDAG). Hence, they maintain that John 17:3 is not contrasting the Father with his Son or the Holy Spirit. So despite the fact that "only" could be a delimiter or exclude others as in "Johnny is the only student in this class who behaved today," Trinitarians do not construe the word that way in 17:3. How convenient, despite the fact that nothing in the context suggests that Jesus was contrasting false gods with his Father.

On further reflection, I think what Trinitarians claim is that Jesus said his Father is "the only true God," not "only the Father is the true God."

My point is not whether John 17:3 can be understood as Trinitarians propose but it's the fact that "only" doesn't exclude others from being called "true God" according to them. They believe that more than one person is "the only true God" though Jesus addressed his words to the Father and seemed to distinguish the "only true God" from himself (i.e., "and the one whom you sent forth"). 

What about Matthew 24:36? According to that verse, only the Father knows the day and hour when the end or tribulation will occur. Neither the angels in heaven nor the Son and apparently the Holy Spirit does not know. Well, despite the use of "only" in that passage, Trinitarians assert that the Son probably knows qua Son (i.e., according to his divine nature) and they claim the Holy Spirit knows based on other texts (1 Corinthians 2:10, for example). So for Trinitarians, "only" doesn't always mean "alone of its or their kind; single or solitary."

1 Timothy 6:16 is a contentious verse. Does it apply to the Father or to the Son? Both answers have been given by scholars and Trinitarians, but however we identify the passage's referent, it speaks about one "alone" having immortality. Are we supposed to believe that the Father only has immortality? Maybe the Son is the only immortal being and his Father is not. How will Trinitarians cut the Gordian knot? Historically, they have qualified the word "alone."

For an example in the Hebrew Bible, see Deut. 32:12.
