You really do leave a lot of Scripture out to present about half the truth.
Please note the underlined section with Peter speaking and the second underlines section with James affirming what Peter said and then moving on to speak about dietary laws.
Acts, chapter 15
CHAPTER 15
1* Some who had come down from Judea were instructing the brothers,a “Unless you are circumcised according to the Mosaic practice,b you cannot be saved.”* 2
Because there arose no little dissension and debate by Paul and Barnabas with them, it was decided that Paul, Barnabas, and some of the others should go up to Jerusalem to the apostles and presbyters about this question.
3They were sent on their journey by the church, and passed through Phoenicia and Samaria telling of the conversion of the Gentiles, and brought great joy to all the brothers.
4When they arrived in Jerusalem, they were welcomed by the church, as well as by the apostles and the presbyters, and they reported what God had done with them.
5But some from the party of the Pharisees who had become believers stood up and said, “It is necessary to circumcise them and direct them to observe the Mosaic law.”
6* The apostles and the presbyters met together to see about this matter.
7* After much debate had taken place, Peter got up and said to them, “My brothers, you are well aware that from early days God made his choice among you that through my mouth the Gentiles would hear the word of the gospel and believe.c 8And God, who knows the heart, bore witness by granting them the holy Spirit just as he did us.d
9He made no distinction between us and them, for by faith he purified their hearts.e
10Why, then, are you now putting God to the test by placing on the shoulders of the disciples a yoke that neither our ancestors nor we have been able to bear?f
11On the contrary, we believe that we are saved through the grace of the Lord Jesus,g in the same way as they.”*
12The whole assembly fell silent, and they listened while Paul and Barnabas described the signs and wonders God had worked among the Gentiles through them.
13* After they had fallen silent, James responded, “My brothers, listen to me.
14Symeon* has described how God first concerned himself with acquiring from among the Gentiles a people for his name. 15The words of the prophets agree with this, as is written:
and rebuild the fallen hut of David;
from its ruins I shall rebuild it
and raise it up again,
17so that the rest of humanity may seek out the Lord,
even all the Gentiles on whom my name is invoked.
Thus says the Lord who accomplishes these things,
18known from of old.’
19i It is my judgment, therefore, that we ought to stop troubling the Gentiles who turn to God, 20but tell them by letter to avoid pollution from idols, unlawful marriage, the meat of strangled animals, and blood.j 21For Moses, for generations now, has had those who proclaim him in every town, as he has been read in the synagogues every sabbath.”
You might notice the the apostles and presbyters (your magisterium) are NOT the church...The church is the assembly of lay people...
James on Dietary Law.
Obviously you intend to claim that James only spoke of dietary law while Peter was the big schmooze in charge of all affairs...
But as we can see, you are wrong again...
19i It is my judgment, therefore, that we ought to stop troubling the Gentiles who turn to God, 20but tell them by letter to avoid pollution from idols, unlawful marriage, the meat of strangled animals, and blood.j 21For Moses, for generations now, has had those who proclaim him in every town, as he has been read in the synagogues every sabbath.”
What I actually did was to show "Then all the multitude kept silence" was in reference to Paul and Barnabas giving testimony, and that it was James who gave the definitive decree, not Peter, and which Truth is what was not at all provided.
Since the mention of all the multitude keeping silence is in reference to hearing Paul and Barnabas, it may infer that disputes were still going on while Peter spoke, which is contrary to the Roman papacy in which all the church looked to Peter to settle a matter.
This does not impugn the leadership of Peter, which i affirmed, but is contrary to the Romish idea of Peter, and is like that of the Orthodox.
Peter as the leader did first provide the basic sound consul, as the first to use the keys of the kingdom of God, the gospel message by which souls enter the kingdom of Christ, (Col. 1:13) but which "proves too much," as what it testifies to is that of a gospel in which souls are forgiven and born again by faith before expressing that faith in baptism;
And when there had been much disputing, Peter rose up, and said unto them, Men and brethren, ye know how that a good while ago God made choice among us, that the Gentiles by my mouth should the word of the gospel, and believe . And God, which knoweth the hearts, bare them witness, giving them the Holy Ghost, even as he did unto us; And put no difference between us and them, purifying their hearts by faith . (Acts 15:7-9)
Next, it was James which gave the definitive 175 word decree, confirmatory of Peter's counsel which Paul and Barnabas observably held also to, but after they had held their peace James is the one that provides the conclusive and Scriptural decree on what should be done, which pleased the apostles and elders. (Acts 15:13-22)
