“Now the apostles and the brothers who were throughout Judea heard that the Gentiles also had received the word of God. And when Peter came up to Jerusalem, those who were circumcised took issue with him, saying, “You went to uncircumcised men and ate with them.” (Acts 11:1–3, LSB)
People were saved, and yet there is criticism.
Note that even in the greatest blessings within the church, there is always at least one person (or two) willing to see the negative side. And notice that the problem they have with this is an unbiblical tradition that was broken.
How does Peter respond? Here we have a wonderful example! Peter is calm and patient. He explains the situation, brings biblical clarity, and then humbly awaits the church to share its wisdom. In this instance, they concurred with Peter.
Had the majority agreed with the circumcision party, I do not think Peter would have bowed out and remained silent. However, his first response was to trust the Spirit to lead the leaders, and if they were not led by the Spirit, then I think Peter would have continued to passionately reason with them from the Word.
Here is the balance of Spirit and truth; shepherding and yet being shepherded. Let us learn both.
