1. The denial of Jesus' divine nature - Certain groups in early church history, the Socinians during the Reformation, and the Unitarians and other modern liberal theologians today, have taught that Jesus was not divine, but only human. This false teaching denies the numerous verses that ascribe divine names, attributes, works, and honors to Christ, as well as the testimonies of His divinity found in Scripture.
2. The denial of Jesus' human nature - the Gnostics in early church history and other groups later have denied Jesus' human nature. They teach that Jesus was divine and that His human nature was only a form through which He revealed Himself. This error denies the scriptural references of Jesus' conception, birth, development, suffering, death, burial, etc. According to this teaching, Jesus, as a Person, did not actually experience these things; they only happened to the human form He was using.
3. The denial of both Jesus' human and divine natures -The Arians in early church history and th,~ Jehovah's Witnesses today teach that Jesus was created as neither God nor man. He was created as the highest creature - above the angels but below God. This belief denies the scriptural references to both Christ's divinity and humanity.
4. The denial of the unity of the two natures in the Person of Christ - Nestorius taught that the two natures of Christ were not united in one essence or person in Christ. Jesus was a union of two persons in one. This union was similar to human marriage - two distinct persons becoming one. They are bound together in one union, but remain two separate persons. The Nestorians viewed Christ as two different persons who were morally agreed and bound together in purpose and action. This error denies the scriptural teachings that the Mediator must be God and man in one, sinless Person.
Socinians - Followers of the Socinus brothers, who taught that Christ was only human, but after His death was exalted to participate in God's rule and power
Unitarians - Deniers of the Trinity; believers in one transcendent God and in Jesus only as an excellent human example to follow
Gnostics - Believers that the soul and spiritual aspects of man were good - created by a "good god," and that man's physical body was evil - created by an "evil god." Jesus was only spiritual. He descended upon and used a human body for some time and then departed, but He was not human
Arians - Followers of Arius (fourth century A.D.) who taught that Jesus was the first and highest of all created beings, neither God nor man
Nestorius - Appointed Bishop of Constantinople in A.D. 428, he taught that Jesus was actually two persons - closely bound together, yet remaining distinct persons
