1 Corinthians 1:11-13 – “It has been reported to me by Chloe’s people that there are quarrels among you, my brothers and sisters. What I mean is that each of you says, ‘I belong to Paul,’ or ‘I belong to Apollos,’ or ‘I belong to Cephas,’ or ‘I belong to Christ.’ Has Christ been divided?“
One thing that always amuses me about this passage is that Paul puts the people who say “I belong to Christ” in the same group as the sectarians. We cannot overcome sectarianism by setting ourselves up in opposition to it. It is natural to seek fellowship with other people who think the same way. Even people who simply “follow Christ” have beliefs and values that are of particular personal importance. For some, it is evangelism. For others, it is social causes. Others really emphasize being nonjudgmental.
What causes sects to develop unhealthy dynamics is when there is a lack of trust in the character of people in other groups. But as described in the previous post, if groups respect members of other groups for who they are in Christ, the groups will steer away from harmful discourses.
This does not mean that we have to excuse, condone, or downplay teachings that we take issue with and deem unscriptural. But we can also see that underneath those teachings is legitimate passion that comes from God. If two groups of Christians with clashing beliefs can see this foundational passion in each other, their own beliefs will gain nuance and maturity, and unhealthy sectarian dynamics will dissipate.
