Hello Captive
Your points are good even If I don't agree with them.
Yes in some places Paul allows his opinion to come into it. Giving us (on certain issues) some flexibility but after the words you highlight he says..."I certainly think I also have God's spirit" Showing that he knows he is spirit inspired even in his opinion.
I do not see Pauls words as anything but spirit inspired. In early centuries his letters had more provenance than any bible book except maybe the gospels for being inspired. Pauls letters and the Gospels were fully accepted as Bible inspired works by all early scholars. I think once we allow the bible to be sliced up into parts we ignore or discard according to our personal preferences, that this is a mistake. Don't you think so?
You recognise the flock arrangement and Unity but not it's actuality? Not seeing that the greek scriptures show functioning working congregations under a central group of older men and apostles and that we must imitate this?
Acts 16:4
As they traveled from town to town, they delivered the decisions reached by the apostles and elders in Jerusalem for the people to obey.
Acts 15:4
When they came to Jerusalem, they were welcomed by the church and the apostles and elders, to whom they reported everything God had done through them.
Paul did fight for the rights of the gentiles but he did adhere to the congregation arrangement by going to the older men and getting a group decision on it. He was himself an Apostle gifted by spirit inspiration and so someone in authority and so placed to be part of the decision making. This is not the norm for the individual members that were told to imitate and obey with understanding those in authority in the congregations above them.
This is a point of contention with most modern Christians, whom prefer a self-regulated personal belief away from religions but I find that way too unbiblical for my taste to be honest.
Your next point in line with the topic. you say.....
It is clear fthat neither Jesus and Paul would have cast out any person who had the good sense and Spirit not to follow a religion's variable opinions. If Paul treated the conscience and faith of his fellow believers so delicately then, why would it be different now?
I do not agree with this statement and more importanly the bible doesn't either.
2 Thessalonians 3:6
[ Warning Against Idleness ] In the name of the Lord Jesus Christ, we command you, brothers, to keepaway from every brother who is idle and does not live according to the teaching you received from us.
Romans 16:17
I urge you, brothers, to watch out for those who cause divisions and put obstacles in your way that are contrary to the teaching you have learned. Keepaway from them.
This next one is even more absolute by Paul.
2 Thessalonians 3:14
If anyone does not obey our instruction in this letter, take special note of him. Do not associate with him, in order that he may feel ashamed.
We may have to agree to disagree on this one but your points were interesting to read. Thank you.
