In His prayer did Jesus abandon the Shema He gave in Mark 12:29?
There is no verse in the bible that shows Jesus abandoned the Shema when he prayed in John 17:3.The Father is a single Person and is the only God, as John 5:44 also show. Jesus, his apostles and the apostles' ancestors did not teach a God different from the God of the Shema as Acts 3:13 show.
John 17:3 ASV
And this is life eternal, that they should know thee the only true God, and him whom thou didst send, even Jesus Christ
John 5:44 ASV
How can ye believe, who receive glory one of another, and the glory that cometh from the only God ye seek not?
Acts 3:13 ASV
The God of Abraham, and of Isaac, and of Jacob, the God of our fathers, hath glorified his Servant Jesus; whom ye delivered up, and denied before the face of Pilate, when he had determined to release him
About the Shema
The word "one" in the Shema in Mark 12:29 is εἷς (heis) not hen as shown in John 17:21-22.
The one/heis (masculine) in Mark 12:29 means mathematical oneness. It does not carry the meaning describing a figurative unity of purpose just as the Greek “one” hen (neuter) does in John 17:21, 22
The context in Deuteronomy 6:4's echad, does not show a plural oneness, Echad means the cardinal number 1 we use in counting. Jesus never stated or even hinted that he and the Father composed the one true God. According to Jesus, his and his Father's testimonies equals 2 testimonies as John 8:17-18 shows, Jesus said that the testimony of two men is true I am he that beareth witness of myself and the Father that sent me beareth witness of me. Thus, Jesus cannot be the only true God as his God is and be counted as "one", the cardinal number 1, as John 8:17-18 show. The only true God is not a compound unity of persons.
Part of another poster's answer stated "If the Father is the only person who can be God, then the Father cannot therefore also be Lord because there is only one Lord. But that’s not what is being said. It’s not said to the exclusion of the other".
Examining the above-mentioned assertion I found;
Jesus referred to Psalm 110:1 as Matthew 22:45-46 and Mark 12:37 show. Does Jesus' statement in Mark 12:36 reinforce the idea that "If the Father is the only person who can be God, then Father cannot therefore also be Lord because there is only one Lord". Mark 12:36 says "David himself said in the Holy Spirit, The Lord said unto my Lord, Sit thou on my right hand, Till I make thine enemies the footstool of thy feet".
Let us examine who the two lords are and if they both are God.
Psalm 110:1 ASV
A Psalm of David. Jehovah saith unto my Lord, Sit thou at my right hand, Until I make thine enemies thy footstool.
The 1st LORD in Psalm 110:1 is Jehovah/YHWH. The second lord is translated from the hebrew word adoni. The word adoni does not refer to God. Adoni is a title which never refers to God. Peter narrated God's plan based on the truth of Psalm 110:1 in Acts 2:33-36. "Being therefore by the right hand of God exalted, and having received of the Father the promise of the Holy Spirit, he hath poured forth this, which ye see and hear. For David ascended not into the heavens: but he saith himself, The Lord said unto my Lord, Sit thou on my right hand, Till I make thine enemies the footstool of thy feet. Let all the house of Israel therefore know assuredly, that God hath made him both Lord and Christ, this Jesus whom ye crucified".
God is the first LORD(YHWH) and Jesus is the second lord(adoni) in Psalm 110:1. God is (LORD) YHWH . Jesus is adoni lord, not LORD (YHWH)
There is no biblical support showing that Jesus abandoned the Shema when he prayed to his Father/God in John 17:3. There is also no support that he is the God of the Shema
