Universalism is a false doctrine that asserts that all men and evil angels will be eventually reconciled to God and "be saved".
This is a dangerous doctrine, since it lulls people into a false hope. The excerpt below is from CHRISTIAN APOLOGETICS & RESEARCH MINISTRY
www.carm.org Universalism
Universalism is the teaching that God, through the atonement of Jesus, will ultimately bring reconciliation between God and all people throughout history. This reconciliation will occur
regardless of whether they have trusted in or rejected Jesus as savior during their lifetime. This universal redemption will be realized in the future where God will bring all people to repentance. This repentance can happen while a person lives or after he has died and lived again in the millennium or some future state.
Additionally, a few universalists even maintain that Satan and all demons will likewise be reconciled to God. Nevertheless, both facets of universalistic belief are in error. People will suffer eternal damnation (Rev. 14:11) and the demonic forces have no redeemer. But, it is important to note that holding to universalism in itself does not make one a non-Christian. Universalism alone is simply a non-essential theological error held by some people.
However, there are those within the universalist camp who also deny the doctrine of the Trinity and, thereby, the incarnation of the Word of God as God the Son. They also deny the personhood and deity of the Holy Spirit. Usually, these denials are held by Unitarian Universalists, though others who are not of the Universalist camp also deny the Trinity. Those who deny these essentials cannot be classified as Christians. To deny the deity of Christ, is to deny one of the essential doctrines of salvation. In this sense, those universalists who deny the deity of Christ are in a false religious belief system. Of course, when one essential doctrine is denied, many other historic biblical doctrines are also denied and salvation is void because the object of faith is false.
