How Far Does Someone Need to Be "Off" About Jesus for Him Not to Be Jesus Anymore? It Is Not Good or Helpful to Accept or Approve a False Jesus

Is the Mormon Jesus, the Jesus of the Bible?  The Moslem Jesus?  The Roman Catholic Jesus?  The Jewish Jesus?  The Charismatic Jesus?  Is the evangelical Jesus the biblical one?

There is only one Jesus, the One in scripture.  However, the Apostle Paul writes in 2 Corinthians 11:4,

For if he that cometh preacheth another Jesus, whom we have not preached, or if ye receive another spirit, which ye have not received, or another gospel, which ye have not accepted, ye might well bear with him.

Someone may preach "another Jesus," just like there are other "gods," according Exodus 20:3, "Thou shalt have no other gods before me."  John writes in 1 John 2:18,

Little children, it is the last time: and as ye have heard that antichrist shall come, even now are there many antichrists; whereby we know that it is the last time.

Antichrists will exist, even as they have through history since actual Jesus Christ.  The doctrine of Christ relates to knowing and believing the right Jesus unto which John again writes in 2 John 1:9,

Whosoever transgresseth, and abideth not in the doctrine of Christ, hath not God. He that abideth in the doctrine of Christ, he hath both the Father and the Son.

Just because other Christs were invented in previous ages and in different occasions of time doesn't mean that more of them will not still come.  The false Christ relates to the imagination unto which Paul writes in 2 Corinthians 10:3-5,

3 For though we walk in the flesh, we do not war after the flesh: 4 (For the weapons of our warfare are not carnal, but mighty through God to the pulling down of strong holds;) 5 Casting down imaginations, and every high thing that exalteth itself against the knowledge of God, and bringing into captivity every thought to the obedience of Christ.

Someone can have a false Christ crafted in his own imagination.  A common apostasy is the creation of an idol.  The idol doesn't need to be a physical one, but also can be a spiritual one in someone's mind.  He invents a Christ in his mind and that Christ conforms to himself, just as communicated in the warning of Romans 1:21-23:

Because that, when they knew God, they glorified him not as God, neither were thankful; but became vain in their imaginations, and their foolish heart was darkened. Professing themselves to be wise, they became fools, And changed the glory of the uncorruptible God into an image made like to corruptible man.

What are the characteristics of man to which he would turn his god or his Jesus?  He would turn God or Jesus into the image of his own lust.  He would create a Jesus, who not only tolerates his lust, but accepts false worship characterized by lust, which is against the nature of God or the Lord Jesus Christ.  This is "another Christ."

The perversion of Jesus into another Jesus either adds or takes away from the true Jesus.  One commonality of a false Jesus is He might not completely save or cannot do so, requiring then good works to save in addition to what he has done.  Many Christian denominations or religions do this.  Peter, John, and Paul all three in their epistles deal with what I'm addressing here.  John has much in his three epistles and in every chapter.

Just as an example, in 1 John 2:9, John writes:

He that saith he is in the light, and hateth his brother, is in darkness even until now.

The person John describes is either deceptive or deceived.  He says he's in the light.  He either knows he's not or he thinks he is and he doesn't know that he isn't.  Two verses later (v. 11), John says this person is deceived:

But he that hateth his brother is in darkness, and walketh in darkness, and knoweth not whither he goeth, because that darkness hath blinded his eyes.

This person doesn't even know that he isn't walking in the light, because darkness has blinded his eyes.  He thinks he's right and he's not.  Many professing Christians think they are right for various reasons.  What I've noticed in many of the instances is that they compare themselves with other professing Christians.  They must be right, because they know other people who are like them or worse.

Is this above described hate just something arbitrary or ambiguous, just a feeling or impression?  Does he detest this person?  It's not like that in verse 10:

He that loveth his brother abideth in the light, and there is none occasion of stumbling in him.

John brings two characteristics.  The one who loves his brother abides in the light, that is, he abides in doctrinal and practical light.  He is believing and practicing according to scripture.    Second, he brings no occasion of stumbling.  He doesn't want to cause a brother to stumble.  How does someone cause someone else to stumble?  This is not a synonym of not walking in the light.  Someone can cause someone to stumble, according to the Apostle Paul in 1 Corinthians 8, by abusing a Christian liberty.  Paul said that eating meat offered unto idols caused someone to stumble.  Jesus mentions this same cause of stumbling twice in Revelation 2-3 and forbids it both times.

If someone dishonors and disobeys his parents, he is not walking in the light.  By dishonoring and disobeying his parents, he could also be causing someone to stumble.  Those two can overlap.  Paul says that someone hates his brother by not walking in the light and then by causing someone to stumble.  This is how someone hates someone.

John says much more in his epistle, but many people are deceived into thinking that have a true Jesus when they don't.  Their Jesus approves of those who don't walk in the light and those who also cause others to stumble.  Jesus is the light of the world.  We walk in the light as Jesus is in the light.  God is light and in Him is no darkness at all.

I see perpetual disobedience to the Word of Christ, to scripture, by professing Christians, and yet they think they are walking in the light.  They are walking in darkness.  This is why they have no problem with sensual, worldly, and fleshly worship.  It's not even that their Jesus accepts it.  They aren't thinking about whether He receives it, because they are thinking about what it does for themselves.  They are shaping their music according to their own lust, and they think it's good because they like it.  Those singing it look and act like secular performers and their style is one that conforms to the world.  This is unacceptable to the Lord (Romans 12:1-2).

If a professing Christian as a practice engages in false worship, is that walking in the light?  Is that loving a brother?  Is that causing others to stumble?

The only thing worse than a false Jesus to those with a false Jesus is pointing out their false Jesus.  They love the Jesus they can conform to themselves, not the one in the Bible.
