Imagine one “universal church” gathering every Sunday—a single assembly claiming to be the Body of Christ, who all believe all are spiritual siblings. In this one gathering, everything contradictory happens simultaneously:
In one corner, a group teaches that water baptism isn’t necessary; across the aisle, another insists it is essential.
One crowd worships with instruments; another says instruments are sinful.
Some insist speaking in tongues is required; others reject it entirely.
A woman rises to preach and have authority over the men, while nearby, others condemn her for doing so.
One table observes the Lord’s Supper weekly; another says it is unnecessary.
Some proclaim “once saved, always saved,” while others warn believers can fall away and apostatize.
One group mandates tithing, another leaves giving entirely to personal discretion.
One insists on elders and deacons, another ignores church leadership altogether.
One follows a single pastor, another allows multiple.
One teaches a pre-tribulation rapture, another a post-tribulation view; one affirms amillennialism, another historic premillennialism.
Some are Calvinistic; others reject it outright.
All these groups claim to be part of the same church and be siblings in Christ, yet they teach directly opposing doctrines, theology, and practices.
The absurdity is clear: if all of these conflicting beliefs and practices are truly part of Christ’s Body, then Jesus, as Head, would simultaneously be commanding contradictory teachings. That is impossible. Christ does not contradict Himself—John 14:6 says, “I am the truth,” and Titus 1:2 affirms that God cannot lie.
By claiming that all these contradictory beliefs are part of the one Body of Christ, effectively promotes confusion, contradiction, and disunity. Scripture, however, says, “God is not the author of confusion but of peace” (1 Corinthians 14:33).
No rational analogy can reconcile all these opposing teachings into a single, functioning body. It’s as if you tried to fly a plane where one pilot insists seatbelts are optional, another says they are required; one flight attendant reads safety instructions, another skips them; emergency exits are pointed in opposite directions. Chaos would ensue. Denominationalism operates the same way: it combines contradictions, claiming all are equally valid, yet the Bible reveals that God’s truth is clear, knowable, and meant to be followed without compromise.
