Brothers we not biting Sola Scriptura precisely because it is never taught in scripture or by the Church.
The Church can make the call for it, it has the authority.given by Jesus:
Matthew 18
18“Truly I say to you, whatever you bind on earth shall have been bound in heaven; and whatever you loose on earth shall have been loosed in heaven.
Jesus Christ gave specific instructions what to do if someone steps out of line including stepping out of line with teaching.
Matthew 18
15“If your brother sins, go and show him his fault in private; if he listens to you, you have won your brother.
16“But if he does not listen
to you, take one or two more with you, so that BY THE MOUTH OF TW
R THREE WITNESSES EVERY FACT MAY BE CONFIRMED.
17“If he refuses to listen to them, tell it to the church; and if he refuses to listen even to the church, let him be to you as a Gentile and a tax collector.
18“Truly I say to you, whatever you bind on earth shall have been bound in heaven; and whatever you loose on earth shall have been loosed in heaven.
If scripture was the Final Authority we would have been stuck a Judaisers requiring circumcision. There was zero scripture to back up against it, it was overruled by the authority of the Church.
Acts 15
1Some men came down from Judea and
began teaching the brethren, “Unless you are circumcised according to the custom of Moses, you cannot be saved.”
2And when Paul and Barnabas had great dissension and debate with them,
the brethren determined that Paul and Barnabas and some others of them should go up to Jerusalem to the apostles and elders concerning this issue.
3Therefore, being sent on their way by the church, they were passing through both Phoenicia and Samaria, describing in detail the conversion of the Gentiles, and were bringing great joy to all the brethren.
4When they arrived at Jerusalem, they were received by the church and the apostles and the elders, and they reported all that God had done with them.
5But some of the sect of the Pharisees who had believed stood up, saying, “It is necessary to circumcise them and to direct them to observe the Law of Moses.”
God gave direct command and vision to Peter to overturn scripture.
If Jesus, The Apostles and the Church went by Sola Scriptura we would be forced to be circumcized and not even allowed to eat with Gentiles.
