The sermon confronts the controversial textual issue surrounding 1 John 5:6–8, particularly the so-called 'Johannine Comma'—the passage affirming the Trinity in heaven and on earth. While many modern translations and scholars argue the verses were added later, the preacher defends their authenticity by citing early Latin and Greek sources, including a fourth-century reference by Cyprian, which predates the alleged 15th-century insertion. He challenges listeners to evaluate claims not by scholarly consensus alone but by Scripture itself, urging discernment and reliance on God's Word over human opinion. The tone is pastoral and instructive, emphasizing humility, careful study, and the enduring authority of Scripture. Ultimately, the message affirms that the Trinity is a foundational truth rooted in biblical witness, not mere tradition.
