Observation: Paul is discussing the nature of internal conflict in the church, and the general principle is simple ... do not argue about the unsettled matters of faith and faithful living, do not judge others for which side of those issues they align with, and do not hurt each other by imposing your opinion of those issues on others or judging them for theirs.
Of course, in the first century and especially in the context of Christianity - with roots in Judaism - this issue is best summarized with the example of food purity. Jews had strict laws about clean and unclean food and Gentiles had no such rules, and thus Christian gatherings involving Jews and non-Jews became problematic quickly. It is very, very interesting to see Paul's take on this matter. He states that he is "persuaded" that "nothing is unclean in itself." This is certainly a total reversal from his life as a Pharisee, who would have not only known in very clear detail which foods were clean and unclean, but would have been very careful observing those laws, would have harshly judged anyone violating those laws, and would have gone a step further to even have rituals and practices in the handling of clean foods to ensure they remained ceremonially clean.
Paul now understands ... nothing is unclean "in itself". Yes, for the Jews, God gave them laws, and those laws required certain actions as part of the nation's obedience to the Lord. That did not make these items bad ... what was bad was willfully disobeying the Lord.
Paul also now understands a second element of this ... not everyone is under the same set of laws, commands, and instructions. Gentiles are not subject to Jewish food purity laws, for example. However, they may be under some other instruction. For example, a person who has heard from the Lord that should fast must therefore fast, and not be judged by others for skipping a festival meal.
Yes, Paul does recognize there are certain settled matters of faith and obedience. He differentiates settled vs. "disputed" matters (v1), and in other letters calls out compliance with moral law since these were reiterated by Jesus. He gives guidelines to some churches while sometimes himself acting differently, because he recognized certain rules apply to the unique circumstances of a specific situation. In all this, Paul's heart has been flipped to understand this ... we have common moral laws with which we strive to comply, but we also have our own individual instructions from the Lord.
Application: I know that much of the conflict of our current society - the part that the Church itself is struggling to reconcile - revolves around this matter of what elements of the Lord's teaching require moral compliance, and what aspects have flexibility that involves individual relationship with God ... and how do we love others my understanding when to correct and when to avoid conflict. I believe we have individuals who hear God's word today just like Paul did, and they seem unified in understanding this matter. Therefore, I'm not too worried about how the Church decides such matters. However ... how do I understand my "settled" matters?
I am mad because of the attacks against my family right now, and most of these attacks are coming from human actions. Hit-and-run accidents, vandalism and theft, hostile words ... these all come against us in the last few days alone. That said, these are coming from outside the body of believers - from non-believers - and thus there is a different standard to apply for assessing and responding to such behavior,
It is the behavior of believers that Paul is addressing, and that includes me. Some of my behavior is outside of the settled, understood instructions of Jesus and I must correct that. Some of my behavior may not be completely understood by other believers, but I hope it aligns to God's instructions for my life. And likewise, I must respect what other believers are called to do.
I judge others too easily, and fail to judge my own actions within the correct context of God's instructions. This I must address.
Prayer: Lord, again I ask you to help me in my mind and my heart and my soul. I go down paths in my heart every day that are against your will, and I wish to stop such actions. Please help. As a secondary matter, please be with my family. Yes, we are clearly under attack, and we desire your protection. We can lean into your love and gain your strength, but it would be wonderful if these attacks would cease. Between violence and sickness, we are all exhausted. Thank you for your love. Amen.
