It should come as no surprise that Jesus Christ is the centerpiece and lynchpin of Christianity. I mean, it’s kind of in the name: Christ-ianity, Christianity. Jesus is the one on whom we fix our eyes, and Jesus is the one who constitutes Christianity. Without Him, it all falls apart, and there is no Christianity.

Therefore, it should also come as no surprise that the most serious and prevalent doctrinal errors concern who Jesus is and what Jesus did. Apostle John points one of those errors out to us in 1 John 3. He writes, “Beloved, do not believe every spirit, but test the spirits to see whether they are from God, for many false prophets have gone out into the world. By this you know the Spirit of God: every spirit that confesses that Jesus Christ has come in the flesh is from God, and every spirit that does not confess Jesus is not from God. This is the spirit of the antichrist, which you heard was coming and now is in the world already.”

So, Apostle John is pointing us to an error concerning Christ where it is taught that Jesus did not really take on human flesh, did not really come in human flesh. It only looked like he did. It’s basically saying that Jesus wasn’t truly human. Historically, this christological heresy is known as docetism and must be rejected. Yes, Jesus was truly and fully God, but He was also truly and fully man. He was both.

Of course, there is the opposite heresy, which is more prevalent today. It’s the belief that Jesus was only a man. Those who believe this basically say, Jesus was a great man, but He was not God. And so, His divinity, His godness is denied. Historically, this christological heresy has been called ebionism and must be rejected. Yes, Jesus was truly and fully man, but He was also truly and fully God. Again, He was both.

There are many more heresies concerning Christ that I could mention, but these two are enough to get us started in the right direction of making sure that we understand who Jesus is and what Jesus did correctly, which is to say biblically. If you don’t have the right Jesus, you don’t have Christianity. Make sure you do!

Change begins in you!
