With respect to all, Y'shua is G_d and One in plural majesty with the Father. I'm Jewish and I believe not in a Catholic trinity, but a tri-unity.
Y'shua also warns us that unless we "Believe that I AM He" will die in our sin. Y'shua received the worship of Thomas, who knelt before Him and exclaimed of Y'shua, my LORD AND my GOD. Y'shua did not rebuke Thomas for blasphemy but instead said, "How blessed you are to have seen and believed in me [as God and Messiah]. How blessed are those who have not seen and believe."
With respect, scripture assures us that God is not a man or a son of man
NUM 23:19 God is
not a man, that he should lie; neither the son of man, that he should repent: hath he said, and shall he not do it? or hath he spoken, and shall he not make it good?
1SAM 15:29 And also the Strength of Israel will not lie nor repent: for he is
not a man, that he should repent.
JOB 9:32 For he is
not a man, as I am, that I should answer him, and we should come together in judgment.
Hosea 11:9 For I am God, and
not man– the Holy One among you.
Jesus expected Jews, including himself and his eye-witness apostles, to consider The Father (Who is spirit) alone as God
JN 4:24
God is a Spirit: and they that worship him must worship him in spirit and in truth.
JN 8:54 Jesus answered, If I honour myself, my honour is nothing: it is
my Father that honoureth me; of whom ye say, that he
is your God:
JN 20:17 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.
Jesus stated truthfully that Jesus was both a man and a son of man. Jesus told us that God is spirit and Jesus stated that Jesus is not spirit. Jesus told us The Father is his God and is greater than Jesus.
I believe Jesus and his eye-witness apostles who assured us that Jesus was 'a man' approved by God and God was with him.
LK 24:39 Behold my hands and my feet, that it is I myself: handle me, and see; for
a spirit hath not flesh and bones, as ye see me have.
Act 2:22 Ye men of Israel, hear these words; Jesus of Nazareth,
a man approved of God among you by miracles and wonders and signs, which God did by him in the midst of you, as ye yourselves also know:
Acts 2:23
This man was handed over to you by God’s set purpose and foreknowledge; and you, with the help of wicked men, put him to death by nailing him to the cross.
ACTS 10:38 How God anointed Jesus of Nazareth with the Holy Ghost and with power: who went about doing good, and healing all that were oppressed of the devil; for
God was with him.
God doesn't sleep PS 121:4 Behold, he that keepeth Israel shall neither slumber nor sleep.
Jesus slept MT 8:24 And, behold, there arose a great tempest in the sea, insomuch that the ship was covered with the waves: but he was asleep.
Thomas was in shock. What he said was the equivalent to the modern term of surprise 'OMG', and Jesus mercifully recognized his shocked state and did not tick him off, like he also didn't tick off Peter for using socially unacceptable language when he unexpectedly saw Jesus after the resurrection. A shocked person's comments should not be considered as literal or correct ... whatever term Peter used was obviously not printable or an accurate description of Jesus, but Jesus allowed for the shock state and the resultant words.
If you are Jewish, I don't know how you could consider God as being a tri-unity from scripture which Jesus quoted before the NT was written for him to refer to.
What man do you think is the Jewish God in Tanach or don't you think the Jewish God became a tri-unity human until after the NT was written so Jesus didn't quote him?
Jesus said God is a spirit. If Jesus believed that God was a trinity or tri-unity then he certainly would have said so, but he didn't.
Jesus said this of The Father:
Joh 17:1 These words spake Jesus, and lifted up his eyes to heaven, and
said, Father, the hour is come; glorify thy Son, that thy Son also may glorify thee:
Joh 17:2 As thou hast given him power over all flesh, that he should give eternal life to as many as thou hast given him.
Joh 17:3 And this is life eternal, that
they might know thee the only true God, and Jesus Christ, whom thou hast sent.
I believe Jesus, that the Father, Who is spirit and is greater than Jesus according to Jesus, and is the God of Jesus, is the One True God.
I embrace the Father as God. I accept that others embrace alternatives.
