Eph 4:4 There is one body, and one Spirit, even as ye are called in one hope of your calling;
Eph 4:5 One Lord, one faith, one baptism,
Eph 4:6 One God and Father of all, who is above all, and through all, and in you all.
Act 2:36 Therefore let all the house of Israel know assuredly, that God hath made that same Jesus, whom ye have crucified, both Lord and Christ.
You have proven nothing.
The word "made" in Acts 2:36 is the Greek word epoiēsen.
The same word translated "ordained" in the following...
Mark 3:14 And he ordained twelve, that they should be with him, and that he might send them forth to preach,
Ordained? What is that?
In the following, which has the same idea in mind, a different word is used - the word "appointed."
Luke 10:1 After these things the LORD appointed other seventy
also, and sent them two and two before his face into every city and place, whither he himself would come.
These things are supposed to be studied out as a doctrine, teaching, or an idea in general.
Not as one word isolated from the idea itself, and certainly not as understood through our modern day English (which appears to be what you did).
Meaning, the meanings of the words are studied out via seeking out where a same sense is meant not only within (1) different, but also within (2) similar, and also, within (3) same narratives, themes, subjects, and or contexts across the board.
The result being that different words being used for a same sense each shed light as to the actually intended sense.
Besides, Peter has already identified what be is actually talking about.
Acts 2:33 Therefore being by the right hand of God exalted, and having received of the Father the promise of the Holy Ghost, he hath shed forth this, which ye now see and hear. 2:34 For David is not ascended into the heavens: but he saith himself,
The Lord said unto my Lord, Sit thou on my right hand, 2:35 Until I make thy foes thy footstool. 2:36 Therefore let all the house of Israel know assuredly, that God hath made that same Jesus, whom ye have crucified, both Lord and Christ.
Peter's point is that the Father has acknowledged the Son as the Lord and Christ Who had been Prophesied unto Israel.
In other words, that the Father has acknowledged the Son IS this Individual here...
John 1:45 Philip findeth Nathanael, and saith unto him, We have found him, of whom Moses in the law, and the prophets, did write, Jesus of Nazareth, the son of Joseph. 1:49 Nathanael answered and saith unto him, Rabbi, thou art the Son of God; thou art the King of Israel.
Acts 2:30 Therefore being a prophet, and knowing that God had sworn with an oath to him, that of the fruit of his loins, according to the flesh, he would raise up Christ to sit on his throne; 2:31 He seeing this before spake of the resurrection of Christ, that his soul was not left in hell, neither his flesh did see corruption. 2:32 This Jesus hath God raised up, whereof we all are witnesses. 2:33 Therefore being by the right hand of God exalted, and having received of the Father the promise of the Holy Ghost, he hath shed forth this, which ye now see and hear. 2:34 For David is not ascended into the heavens: but he saith himself, The Lord said unto my Lord, Sit thou on my right hand, 2:35 Until I make thy foes thy footstool. 2:36 Therefore let all the house of Israel know assuredly, that God hath made that same Jesus, whom ye have crucified, both Lord and Christ.
Meaning what, Israel?
That you killed your King: the Son of God; your Prophesied Christ - and you'd better get right about that - for God has acknowledged Him as having been exactly that and there will be hell to pay when He arises to make His enemies His footstool!
Intended result?
Acts 2:37 Now when they heard this, they were pricked in their heart, and said unto Peter and to the rest of the apostles, Men and brethren, what shall we do?
2:40 And with many other words did he testify and exhort, saying, Save yourselves from this untoward generation.
Save yourselves from what, Israel?
Why?
Acts 3:22 For Moses truly said unto the fathers, A prophet shall the Lord your God raise up unto you of your brethren, like unto me; him shall ye hear in all things whatsoever he shall say unto you. 3:23 And it shall come to pass, that every soul, which will not hear that prophet, shall be destroyed from among the people.
In short, all that is a doctrine concerning Israel and the Father's having acknowledged that Jesus IS the Father's Prophesied Christ, there, in Acts 2 and 3.
Romans 1:3 Concerning his Son Jesus Christ our Lord, which was made of the seed of David according to the flesh; 1:4 And declared to be the Son of God with power, according to the spirit of holiness, by the resurrection from the dead:
This "made" business - is studied in this way; not via one sole word, nor via one sole word in modern day English.
You are likewise as clueless as to those passages in Ephesians 4 - each passage of which depict a three-fold unity their whole is comprised of.
Where your kind go south is in your failure to see the teaching on Christ when He was on Earth, how that, as Paul put it in Philippians 2: when He came here, He "made himself of no reputation" (emptied Himself of Who He had been as to previous His equality in Glory with that of the Father's), and took on the form of a servant of God, and came to do His Will.
Or as He Himself had described that...
John 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: 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. 17:3 And this is life eternal, that they might know thee the only true God, and Jesus Christ, whom thou hast sent. 17:4 I have glorified thee on the earth: I have finished the work which thou gavest me to do. 17:5 And now, O Father, glorify thou me with thine own self
with the glory which I had with thee before the world was.
The very example Paul makes of that as to what the Believer is to be via the Believer's emptying of him or herself: that he or she might be a vessel fit for the Master's intended use, 2 Tim. 2:21.
Philippians 2:3 Let nothing be done through strife or vainglory; but in lowliness of mind let each esteem other better than themselves. 2:4 Look not every man on his own things, but every man also on the things of others. 2:5 Let this mind be in you, which was also in Christ Jesus: 2:6 Who, being in the form of God, thought it not robbery to be equal with God: 2:7 But made himself of no reputation, and took upon him the form of a servant, and was made in the likeness of men: 2:8 And being found in fashion as a man, he humbled himself, and became obedient unto death, even the death of the cross. 2:9 Wherefore God also hath highly exalted him, and given him a name which is above every name: 2:10 That at the name of Jesus every knee should bow, of things in heaven, and things in earth, and things under the earth; 2:11 And that every tongue should confess that Jesus Christ is Lord, to the glory of God the Father.
Acts 17: 11, 12.
