Idk why you keep saying this when every trinitarian here (including myself) knows and believes that Jesus who was the Word of God and (as scripture says) was God ....came in the likeness of sinful flesh. The fact that He came in the flesh is essential to salvation.
1 John 4:2-3
[2]Hereby know ye the Spirit of God: Every spirit that confesseth that Jesus Christ is come in the flesh is of God:
[3]And every spirit that confesseth not that Jesus Christ is come in the flesh is not of God: and this is that spirit of antichrist, whereof ye have heard that it should come; and even now already is it in the world.
2 John 1:7-8
[7]For many deceivers are entered into the world, who confess not that Jesus Christ is come in the flesh. This is a deceiver and an antichrist.
[8]Look to yourselves, that we lose not those things which we have wrought, but that we receive a full reward.
We must believe that ...Jesus Christ... came in the flesh. If we believe it was some other Jesus (and not the Christ Jesus) ...or we altogether deny He came in a flesh body ...we miss it and will not receive a full reward.
Furthermore....
John 1:1-3,14
[1]In the beginning was the Word, and the Word was with God, and the Word was God.
[2]The same was in the beginning with God.
[3]All things were made by him; and without him was not any thing made that was made.
[14]And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth.
We believe - as the scriptures declare - that the Word of God was made flesh. He came in the likeness of sinful flesh, and yet he knew no sin.
Romans 8:3
[3]For what the law could not do, in that it was weak through the flesh, God sending his own Son in the likeness of sinful flesh, and for sin, condemned sin in the flesh:
2 Corinthians 5:21
[21]For he hath made him to be sin for us, who knew no sin; that we might be made the righteousness of God in him.
He condemned sin in the flesh! Our sins were laid on Him!
Isaiah 53:1-12
[1]Who hath believed our report? and to whom is the arm of the LORD revealed?
[2]For he shall grow up before him as a tender plant, and as a root out of a dry ground: he hath no form nor comeliness; and when we shall see him, there is no beauty that we should desire him.
[3]He is despised and rejected of men; a man of sorrows, and acquainted with grief: and we hid as it were our faces from him; he was despised, and we esteemed him not.
[4]Surely he hath borne our griefs, and carried our sorrows: yet we did esteem him stricken, smitten of God, and afflicted.
[5]But he was wounded for our transgressions, he was bruised for our iniquities: the chastisement of our peace was upon him; and with his stripes we are healed.
[6]All we like sheep have gone astray; we have turned every one to his own way; and the LORD hath laid on him the iniquity of us all.
[7]He was oppressed, and he was afflicted, yet he opened not his mouth: he is brought as a lamb to the slaughter, and as a sheep before her shearers is dumb, so he openeth not his mouth.
[8]He was taken from prison and from judgment: and who shall declare his generation? for he was cut off out of the land of the living: for the transgression of my people was he stricken.
[9]And he made his grave with the wicked, and with the rich in his death; because he had done no violence, neither was any deceit in his mouth.
[10]Yet it pleased the LORD to bruise him; he hath put him to grief: when thou shalt make his soul an offering for sin, he shall see his seed, he shall prolong his days, and the pleasure of the LORD shall prosper in his hand.
[11]He shall see of the travail of his soul, and shall be satisfied: by his knowledge shall my righteous servant justify many; for he shall bear their iniquities.
[12]Therefore will I divide him a portion with the great, and he shall divide the spoil with the strong; because he hath poured out his soul unto death: and he was numbered with the transgressors; and he bare the sin of many, and made intercession for the transgressors.
In these following verses, we see that the Word of God (who, as the scriptures have declared, is Jesus Christ) is a discerner of the thoughts and intents of the heart. Many pass right over this. But look at verse 13. The Word of God is given pronouns (his/him) that denotes personhood. This is further confirmed in verse 14, which is clearly speaking of Jesus Christ, our Great High Priest.
Hebrews 4:12-15
[12]For the word of God is quick, and powerful, and sharper than any twoedged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart.
[13]Neither is there any creature that is not manifest in his sight: but all things are naked and opened unto the eyes of him with whom we have to do.
[14]Seeing then that we have a great high priest, that is passed into the heavens, Jesus the Son of God, let us hold fast our profession.
[15]For we have not an high priest which cannot be touched with the feeling of our infirmities; but was in all points tempted like as we are, yet without sin.
Jesus Christ, our Great High Priest, was touched with the feeling of our infirmities (not His own), and He was tempted in every way that we've been tempted. Yet, He had no sin.
We must take the whole scripture. Where it seems to conflict or not say what we want it to say, we need to get with Him on it. (Which to me, it doesn't, because I let it speak for itself.) If we wrest the scriptures, we get into serious trouble. We begin to rationalize with the carnal mind and reason Him away.
2 Peter 3:16-18
[16]As also in all his epistles, speaking in them of these things; in which are some things hard to be understood, which they that are unlearned and unstable wrest, as they do also the other scriptures, unto their own destruction.
[17]Ye therefore, beloved, seeing ye know these things before, beware lest ye also, being led away with the error of the wicked, fall from your own stedfastness.
[18]But grow in grace, and in the knowledge of our Lord and Saviour Jesus Christ. To him be glory both now and for ever. Amen.
