Of course it fits that description! Do you have any better candidate for what this means?
Yet he was subordinate to James at the Council Of Jerusalem???
Show me from Scripture an instance of such subordination and we'll go from there.
Acts 15:
[7] And after there had been much debate, Peter rose and said to them, "Brethren, you know that in the early days God made choice among you, that by my mouth the Gentiles should hear the word of the gospel and believe.
[8] And God who knows the heart bore witness to them, giving them the Holy Spirit just as he did to us;
[9] and he made no distinction between us and them, but cleansed their hearts by faith.
[10] Now therefore why do you make trial of God by putting a yoke upon the neck of the disciples which neither our fathers nor we have been able to bear?
[11] But we believe that we shall be saved through the grace of the Lord Jesus, just as they will."
[12] And all the assembly kept silence; and they listened to Barnabas and Paul as they related what signs and wonders God had done through them among the Gentiles.
[13] After they finished speaking, James replied, "Brethren, listen to me.
[14] Simeon has related how God first visited the Gentiles, to take out of them a people for his name.
[15] And with this the words of the prophets agree, as it is written,
[16] `After this I will return, and I will rebuild the dwelling of David, which has fallen; I will rebuild its ruins, and I will set it up,
[17] that the rest of men may seek the Lord, and all the Gentiles who are called by my name,
[18] says the Lord, who has made these things known from of old.'
[19] Therefore my judgment is that we should not trouble those of the Gentiles who turn to God,
Barnabas and Paul spoke, and James, after listening to the entire discussion, prounounced his judgment.
Peter was a participant, not the leader.
