He tried to proof-text using John 14:28 and Matt 26:39 to say that Jesus Christ, the Ancient of Days, is not and never was God. As a J-W, a new man-created religion of the last 100 years, he wrongly believes Jesus is a man that used many bodies and is St. Michael the Archangel.
The first problem is he is trying to use a verse out of context. So let us read verses around the quoted verses to see what else God the Son is teaching in The Holy Gospel According to Saint John 14:6-27:
Then this chapter ends with the following verse, John 14:31:
Jesus saith to him, "I AM the Way, and the Truth, and the Life; no one cometh to the Father, except by Me. "If ye had known Me, ye would have known My Father also. And from now ye know Him, and have seen Him." Philip saith to Him, "Lord, show us the Father, and sufficeth us." Jesus saith to him, "Am I so long a time with you, and thou hast not known Me, Philip? The one who hath seen Me hath seen the Father; and sayest thou, 'Show us the Father'? "Believest thou not that I AM in the Father, and the Father is in Me? The words which I speak to you I speak not from Myself; but the Father Who abideth in Me, He doeth the works. "Keep on believing Me that I AM in the Father and the Father in Me; otherwise keep on believing Me on account of the works themselves. "Verily, verily, I say to you, the one who believeth in Me, the works which I do shall that one do also; and greater works than these shall he do, because I go to My Father. "And whatsover ye shall ask in My Name, this I will do, that the Father might be glorified in the Son. "If ye should ask anything in My Name, I will do it. "If ye love Me, keep My commandments. "And I will ask the Father, and He shall give you another Paraclete, that He may abide with you forever — "the Spirit of the truth, Whom the world is not able to receive, because it seeth Him not, nor knoweth Him; but ye know Him, for He abideth by you, and shall be in you. "I will not leave you orphans; I am coming to you. "Yet a little while, and the world see Me no longer, but ye see Me; because I live, ye shall live also. "In that day ye shall know that I AM in the Father, and ye in Me, and I in you. "The one who hath My commandments and keepeth them, that one is the one who loveth Me. And the one that loveth Me shall be loved by My Father, and I will love him and will manifest Myself to him. Judas, not the Iscariote, saith to Him, "Lord, then what hath come to pass that Thou art about to manifest Thyself to us, and not to the world?" Jesus answered and said to him, "If anyone love Me, he will keep My word; and My Father will love him, and We will come to him and make an abode with him. The one who loveth Me not keepeth not My words; and the word which ye hear is not Mine but of the Father Who sent Me. I have spoken these things to you, abiding with you; but the Paraclete, the Holy Spirit, Whom the Father will send in My name, that One shall teach you all things, and shall remind you of what I said to you. "Peace I leave to you, My peace I give to you; not as the world giveth, give I to you. Let not your heart continue being troubled, nor being fearful.
"But that the world might know that I love the Father, and even as the Father enjoined Me, thus I do. Arise, let us be going from this place."Obviously He is not saying that He is not one with the Father in the Chapter of the Holy Bible! In fact, if one does not understand that God the Son is one with God the Father, then he never knew the Son at all, and was never taught by God the Holy Spirit! This is straight from the Bible!
As for Chapter 26 of The Holy Gospel According to Matthew, let us look at what the early undivided Church taught about this:
Saint John of Damascus: "When He said, 'O My Father, if it is possible, let this cup pass from Me; however, not as I will, but as Thou wilt,' is it not clear to all that He said this as a lesson to us to ask help in our trials only from God, and to prefer God's Will to our own, and as a proof that He did actually appropriate to Himself the attributes of our nature, and that He did in truth possess two wills, natural, indeed, and corresponding with His natures but yet in no wise opposed to one another? 'Father' implies that He is of the same essence, but 'if this is possible' does not mean that He was in ignorance (for what is impossible to God?), but serves to teach us to prefer God's Will to our own. For that alone is impossible which is against God's will and permission. 'However, not as I will but as Thou wilt,' for inasmuch as He is God, He is identical with the Father, while inasmuch as He is Man, He manifests the natural will of mankind. For it is this that naturally seeks escape form death."Thank God for what He teaches us in his Extreme Humility and Charity!
