The Bible warns against being self-willed or creating factions. Furthermore, James tells us that when it comes in corporate worship, we should not play favorites or create distinctions among one another. Of course, we celebrate family and friendships, but Sunday morning is not to celebrate the people we like the most. It is to celebrate the oneness we have in Christ with each other. That’s what makes us different than the world. That’s what heaven is all about. That’s a biblical church with one accord with each other, not several factions splintered among family and friendship distinctions or at worse 'toxic tribalism.' That gets celebrated outside the body, but not when the body of Christ gathers. Understanding the balance calls for discernment and self-control and love. It calls for Christian maturity.
