Nazarene beliefs are spelled out in the church's Articles of Faith and the Manual of the Church of the Nazarene. Two Nazarene beliefs set this Christian denomination apart from other evangelicals: the belief that a person can experience entire sanctification, or personal holiness, in this life, and the belief that a saved person can lose their salvation through sin.
Baptism - Both infants and adults are baptized in the Nazarene church. As a sacrament, baptism signifies acceptance of Jesus Christ as Savior and willingness to obey him in righteousness and holiness.
Bible - The Bible is the divinely inspired Word of God. The Old and New Testaments contain all the truth needed for faithful Christian living.
Divine Healing - God heals, so Nazarenes are encouraged to pray for his divine healing. The church believes that God also heals through medical treatment and never discourages members from seeking healing through trained professionals.
Entire Sanctification - Nazarenes are a Holiness people, open to complete regeneration and sanctification by the Holy Spirit. This is a gift of God and is not earned through works. Jesus Christ modeled a holy, sinless life, and his Spirit enables believers to become more Christlike day by day.
Heaven, Hell - Heaven and hell are real places. Those who believe in Christ shall be judged by their acceptance of him and their deeds and will receive glorious eternal life with God. The "finally impenitent" will suffer eternally in hell.
Jesus Christ - The Second Person of the Trinity, Jesus Christ was born of a virgin, was both God and man, died for humanity's sins, and bodily arose from the dead. He lives now in heaven as the intercessor for mankind.
Salvation - Christ's atoning death was for the entire human race. Everyone who repents and believes in Christ is "justified and regenerated and saved from the dominion of sin."
Sin - Since the Fall, human beings have a depraved nature, inclined toward sin. However, the grace of God helps people make right choices. Nazarenes do not believe in eternal security. Those who are regenerate and have received entire sanctification may sin and fall from grace, and unless they repent, they will go to hell.
Trinity - There is one God: Father, Son and Holy Spirit.
Sacraments - Nazarenes baptize both infants and adults. If parents choose to delay baptism, a dedication ceremony is available. The applicant, parent, or guardian may choose sprinkling, pouring, or immersion.
Local churches vary on how often they administer the sacrament of the Lord's Supper, some only four times a year and others as often as weekly. All believers present, regardless of whether they are members of the local church, are invited to partake. The minister says a prayer of consecration, then distributes the two emblems of communion (bread and wine) to the people, with the help of other ministers or stewards. Only unfermented wine is used in this sacrament.
Worship Service - Nazarene worship services include hymns, prayer, special music, Scripture reading, a sermon, and an offering. Some churches feature contemporary music; others favor traditional hymns and songs. Church members are expected to tithe and to give freewill offerings to support the missionary work of the global church. Some churches have revised their Sunday and Wednesday evening meetings from worship services to evangelism training or small group studies.
