Before answering, there are a few ways of defining "divinity". I am going to answer from the traditional, orthodox understanding of the term as defined at http://carm.org/dictionary-divinity
Divinity is the nature or quality of being God. Within Christianity it
belongs to God alone. It is also important to note that orthodox
Christianity believes that Jesus was divine in nature (Col. 2:9) as
well as being a man. For more information see Jesus' Two Natures.
There's a pretty comprehensive list of denominations that reject the Trinity here. Groups from that list that also deny the divinity of Christ include:
- Latter-day Saints
- Jehovah's Witnesses
- Christian Science
- Unification Church
- Unity School of Christianity
While not necessarily sects, there are certain teachings that deny both the Trinity and Christ's divinity, which were adhered to by various sects.
Many are found at http://gbgm-umc.org/umw/bible/heresies.stm
- Arianism-- Jesus less than God -- more than human-- The Arian controversy began in Alexandria, Egypt about 318 AD. Arius (c. 250-c.
336) was a popular Alexandrian priest whose theology about who Jesus
was was condemned as heretical by the First Council of Nicaea in 325
and also at the First Council of Constantinople in 381.
- Ebionite-- Jesus regarded as prophet rather than divine Word of God-- Ebionites originally were a first century Jewish-Christian sect.
They emphasized Jewish law and rejected Paul's teachings. Most
considered him to be a man, not God. Later use of this term refers to
anyone who minimizes the divinity of Christ.
- Nestorianism-- Refers to theology of Nestorius of Antioch, who became Bishop of Constantinople in 428 A.D.
Nestorius believed that Mary was mother only of the human Jesus, not
the divine Logos and in the Antiochine "two-nature" Christology.
