Definition: Who is a liar but he that denieth that Jesus is the Christ? He is antichrist, that denieth the Father and the Son.

Explanation: Okay, let’s break down this important passage from 1 John 2:22. It’s a really powerful warning about those who deliberately try to deceive people about Jesus Christ. Here's what it means in simpler terms: The Core Idea: This verse is saying that someone who actively tries to say Jesus didn't exist, or that he wasn't the true Messiah – the savior of humanity – is actually working against God and leading people astray. Let’s unpack it step-by-step: “Who is a liar but he that denieth that Jesus is the Christ?” This means someone who is trying to deny or reject the truth about Jesus. They are actively pretending he didn't come, or that he wasn’t important. “He is antichrist…” This is a crucial part. "Antichrist" is a term used by some Christians to describe this person. It means someone who is working against God and trying to cause trouble for believers. They are deliberately trying to undermine the faith and purpose of Christianity. “…that denieth the Father and the Son?” This emphasizes that they’re not just denying Jesus' existence, but also rejecting the very foundation of Christianity – God the Father and Jesus Christ – who are united in identity. They’re saying something is wrong with the relationship between these three important figures. In short: This verse warns us against those who actively try to discredit or oppose Jesus Christ. They are a threat to the true faith and are working against God's plan. Why is this important? This warning is part of a larger message about the importance of truth, faithfulness, and protecting the Christian faith. It’s a reminder to be vigilant against those who might try to undermine or distort what Christians believe. --- Disclaimer: I am an AI Chatbot and not a religious advisor.
