Was it really adequately dealt with
Yes. Only those who hate Christianity consider Jesus to not be God. If you read those verses as saying that Jesus Christ is somehow less than God, then guess what? You're an Arian. And the Arians were thrown out by the entire Church, and have never, ever been recognized by anyone to be in line with what the apostles taught. So if that's what you think Joseph Smith was 'restoring', then you're condemning your own prophet as a liar and a fraud for claiming to restore original, first century Christianity. It doesn't even fit with Mormonism's own idea of the 'Great Apostasy', wherein Christianity was 'corrupted' by AD 200 (or 170, or whenever), because Arius wasn't even born until 256 AD.
(New Testament | John 14:28)
28 Ye have heard how I said unto you, I go away, and come again unto you. If ye loved me, ye would rejoice, because I said, I go unto the Father: for my Father is greater than I.
Let us look at this not in isolation, but together with
the Apostles' expectation and understanding, which gives the context needed to understand what Christ was saying.
We can do so by looking at it from the very beginning of the chapter. Christ is teaching His apostles:
1 "Let not your heart be troubled; you believe in God, believe also in Me. 2 In My Father's house are many mansions; 3 And if I go and prepare a place for you, I will come again and receive you to Myself; that where I am, there you may be also.
4 And where I go you know, and the way you know." 5 Thomas said to Him, "Lord, we do not know where You are going, and how can we know the way?" 6 Jesus said to him, "I am the way, the truth, and the life. No one comes to the Father except through Me. 7 "If you had known Me, you would have known My Father also; and from now on you know Him and have seen Him." 8 Philip said to Him, "Lord, show us the Father, and it is sufficient for us." 9 Jesus said to him, "Have I been with you so long, and yet you have not known Me, Philip? He who has seen Me has seen the Father; so how can you say, 'Show us the Father'? 10 Do you not believe that I am in the Father, and the Father in Me? The words that I speak to you I do not speak on My own authority; but the Father who dwells in Me does the works. 11 Believe Me that I am in the Father and the Father in Me, or else believe Me for the sake of the works themselves.
12 "Most assuredly, I say to you, he who believes in Me, the works that I do he will do also; and greater works than these he will do, because I go to My Father. 13 And whatever you ask in My name, that I will do, that the Father may be glorified in the Son. 14 If you ask anything in My name, I will do it.
15 "If you love Me, keep My commandments. 16 And I will pray the Father, and He will give you another Helper, that He may abide with you forever-- 17 the Spirit of truth, whom the world cannot receive, because it neither sees Him nor knows Him; but you know Him, for He dwells with you and will be in you.
18 I will not leave you orphans; I will come to you. 19 "A little while longer and the world will see Me no more, but you will see Me. Because I live, you will live also. 20 At that day you will know that I am in My Father, and you in Me, and I in you. 21 He who has My commandments and keeps them, it is he who loves Me. And he who loves Me will be loved by My Father, and I will love him and manifest Myself to him." 22 Judas (not Iscariot) said to Him, "Lord, how is it that You will manifest Yourself to us, and not to the world?" 23 Jesus answered and said to him, "If anyone loves Me, he will keep My word; and My Father will love him, and We will come to him and make Our home with him. 24 He who does not love Me does not keep My words; and the word which you hear is not Mine but the Father's who sent Me.
25 "These things I have spoken to you while being present with you. 26 But the Helper, the Holy Spirit, whom the Father will send in My name, He will teach you all things, and bring to your remembrance all things that I said to you. 27 Peace I leave with you, My peace I give to you; not as the world gives do I give to you. Let not your heart be troubled, neither let it be afraid.
28 You have heard Me say to you, 'I am going away and coming back to you.' If you loved Me, you would rejoice because I said, 'I am going to the Father,' for My Father is greater than I. 29 And now I have told you before it comes, that when it does come to pass, you may believe. 30 I will no longer talk much with you, for the ruler of this world is coming, and he has nothing in Me. 31 But that the world may know that I love the Father, and as the Father gave Me commandment, so I do. Arise, let us go from here.

So He begins by talking to His disciples on the eve of His crucifixion, telling them that He is going away that He might prepare a place for them where He is going (His Father's house/heaven). He says that they know where He is going, and the way there. They do not understand, so makes it more explicit:
"I am the way, the truth, and the life. No one comes to the Father except through Me." So in response to Philip's protest that they do not even know where He is going, so they can't possibly know the way there, He tells them they know the way through knowing Him. And "If you had known Me, you would have known My Father also;
and from now on you know Him and have seen Him." Again, they know Him (the Father) by knowing Him (Christ). But they still don't get it:
Philip said to Him, "Lord, show us the Father, and it is sufficient for us." Jesus said to him, "Have I been with you so long, and yet you have not known Me, Philip? He who has seen Me has seen the Father; so how can you say, 'Show us the Father'? Do you not believe that I am in the Father, and the Father in Me? The words that I speak to you I do not speak on My own authority; but the Father who dwells in Me does the works. Believe Me that I am in the Father and the Father in Me, or else believe Me for the sake of the works themselves.
They are not taking Him at His word, not because they don't believe because they do not understand what those words mean (remember: this is all
before His crucifixion and resurrection), so Jesus says "I don't speak on My own authority; but the Father who dwells in Me does the works." These are religious, first century Jews. They do not necessarily understand every word that Jesus says, but they do understand that God the Father is the One God, because that was a common way to talk about God by that point. So, since they don't understand (yet) what Jesus is saying, since His resurrection has not been made manifest to them, He is essentially saying "If you're not going to believe Me based on what I say, because you don't get it, then recognize that I'm not saying so
of Myself to begin with, but that I say and do what the Father has given me to say and do, so look at the miracles I have already done --
by your own understanding, these are proof in themselves that the Father works through Me, whether you understand what I'm saying right now or not." (Because His saying "If you have seen Me, you have seen the Father" resulted in them asking Him to show them the Father
when that wasn't the point.)
This is all the build-up to the verse you have chosen to isolate from its context, wherein Christ says "
You have heard Me say to you, 'I am going away and coming back to you.' If you loved Me, you would rejoice because I said, 'I am going to the Father,' for My Father is greater than I." Not only can this likewise be understood as the above example is -- Christ talking to His disciples in terms they will understand -- but also is necessary to consider in light of the intervening promise that with His going away, He will send them the Comforter, the Holy Spirit, so that they will not be as orphans after He leaves.
The properly literate Christian understands these things as having been spoken in the time they were (before His crucifixion), to the people they were (first century Jews), in the context they were (the Apostles' anxiety over Jesus' message that He would be leaving them soon), and on the topic they were (Why they should be rejoicing that He is going away). To take any of these away by presenting one 'bald' verse makes it seem as though it is appropriate to conclude based on the verse in isolation that Christ must've been talking about
His own ontological relationship with the Father. This is not the case. That is dealt with all over the chapter, of course ("If you have seen Me, you have seen the Father"), but is not what is dealt with in that verse. We know that because when we read it in context, we can see from the very beginning of the chapter how Christ tailor's His message to what His disciples can understand in the context in which they are, as in the earlier
"I do not speak on My own authority; but the Father who dwells in Me does the works." Would you conclude from this fragment that Jesus is saying that He
does not have authority in Himself? Maybe you would, but I'm going to guess that a Christian would not, because a Christian knows that Jesus also said "All authority has been given to Me in heaven and on earth" (Matthew 28:18), and that this is not attenuated by the fact that it has been
given to Him (by the Father, of course), since of course Christ's ontological relationship with the Father is that He is the incarnate Word of God, so the authority (power, might, eternality, etc.) that He is has
is the Father's authority, because He and the Father are One. It is a testimony to their homoousion relation to one another, not a denial of it.
(New Testament | John 5:36)
36 ¶ But I have greater witness than that of John: for the works which the Father hath given me to finish, the same works that I do, bear witness of me, that the Father hath sent me.
Duh. See everything above. Had the Father not sent Him, He wouldn't have been telling the truth concerning anything He said and did. Christ's earthly life only makes even the slightest bit of sense in the context of His having been sent from the Father.
(New Testament | John 20:17)
17 Jesus saith unto her, Touch me not; for I am not yet ascended to my Father: but go to my brethren, and say unto them, I ascend unto my Father, and your Father; and to my God, and your God.
Again, duh. Also again, Christ's earthly life only makes even the slightest bit of sense in the context of His having been sent from the Father. Christ was incarnate as a first century Jew. Who was the God of the first century Jews? God the Father, the Father of our Lord, God, and Savior Jesus Christ. In light of that,
what else should He have said?
The Father, Son, and Holy Spirit are NOT of the same substance.
They absolutely are. Stop your blasphemy.
These scriptures show that the creeds are wrong.
These scriptures show that you don't understand them. Maybe if you and all Mormons stopped bathing yourselves in the pond scum of the Arians (a.k.a. Joseph Smith's theology) for five seconds, you'd be able to.
