The Church of the Nazarene is the largest denomination in the classical Wesleyan-Holiness tradition. The doctrine that distinguishes the Church of the Nazarene and other Wesleyan denominations from most other Christian denominations is that of entire sanctification. Nazarenes believe that God calls Christians to a life of holy living that is marked by an act of God, cleansing the heart from original sin and filling the individual with love for God and humankind. This experience is marked by entire consecration of the believer to do God's will and is followed by a life of seeking to serve God through service to others. Like salvation, entire sanctification is an act of God's grace, not of works. Our pursuant service to God is an act of love whereby we show our appreciation for the grace that has been extended to us through the death and resurrection of Jesus Christ.

There are two answers to this question. First, God invites us to experience a personal relationship with Him. That invitation is offered to every human on earth. Second, God wants each of us to use our abilities and opportunities to help others. These purposes are different for each of us. As part of traditional Christianity, Nazarenes understand that God created all people with the same intention: Each one should have a loving relationship with God that will last for eternity (John 3:16; 1 John 1:3). When we have such a relationship, God intends for us to become more loving, patient, and self-disciplined; in short, we are on a journey toward a God-shaped life (2 Corinthians 3:18; Galatians 5:22-23; 1 John 3:2). In addition, God gives each person special abilities designed to help others. For example, some are able to teach others about God, some are able to help with physical needs, and some are especially effective in counseling or leadership (Romans 12:6-8; 1 Corinthians 12:7-11).

As part of the Christian community, Nazarenes understand that there is one God, who has always existed and will always exist (Deuteronomy 6:4). We believe that He is creative (Genesis 1; Isaiah 40:25-26) and holy (Leviticus 19:2; Isaiah 5:16, 6:1-7) and that His purposes are carried out in this world (Jeremiah 29:11; Acts 1:6-7). We also understand that God's nature is "three-fold": Father, Son, and Holy Spirit (Matthew 28:19-20; 2 Corinthians 13:14). This concept of God's three-fold nature, the Trinity, was understood by the early Christian Church as the best way to explain what they had experienced. They knew from their Jewish roots that there is only one God, but they also knew that Jesus acted as if He were God. In addition, the Holy Spirit, empowering the church as promised by Jesus and the Old Testament, seemed to have all of God's power as well. Thus they understood that Jesus and the Holy Spirit are parts of the one God who has always existed. Nazarenes embrace this belief borne out by God's Word.

The New Testament writings state that Jesus of Nazareth was born to a Jewish family during the early days of the Roman Empire. He was killed by the Roman occupation forces and truly rose from the dead. Then He joined God the Father in heaven. While those of different faiths consider Him a great religious teacher, the followers of Jesus understood that He was more than just a teacher. He forgave sins (Mark 2:1-12; John 8:1-11); He spoke as if He had always existed (John 8:58); and one of His followers addressed Him as God (John 20:28). His death was more than a simple execution; His death makes it possible for humans to have a restored relationship with God (Colossians 1:21-23). In His continued life with the Father, He still cares for us humans (1 John 2:1-2). The Church of the Nazarene agrees with other Christians that Jesus is God. He is distinct from God the Father, known to the Jewish nation at the time of Moses (Deuteronomy 1:31; Proverbs 3:12). He is also distinct from the Holy Spirit, who has empowered Christians since the earliest days of the Church (Acts 2:4, 33). The Holy Spirit continues the work of Jesus through His followers today (John 16:13-15). While He is God, He is also human. Jesus was born to the Virgin Mary when the power of the Holy Spirit came upon her (Luke 1:26-35). In Him, the nature of God and the nature of humanity are united in one Person (Colossians 1:19-20).

Before Jesus died, He told His followers that He would leave them. He also promised that they would receive "another advocate" who would be with them forever (John 7:37-39, 14:16). After His death and resurrection He told His followers that they would receive power through the Holy Spirit (Luke 24:49; Acts 1:8). He then left His followers (Acts 1:9). Days later, Jesus' followers did receive the Holy Spirit (Acts 2:1-4, 18, 32-33). The church immediately recognized the presence of the Holy Spirit as being equivalent to God's presence (Acts 15:8-9; Ephesians 3:14-19; 1 John 3:24).

Nazarenes, like other Christians, use the term "salvation" to mean turning from wrong actions, receiving God's forgiveness, committing ourselves to God, and living as God directs. Salvation is from the word "save." Jesus declared that He came to "save the lost" (Luke 19:10). When a pagan Roman jailer wanted to become a Christian, he asked, "What must I do to be saved?" (Acts 16:30). When talking to a religious leader, Jesus said that God intended to "save the world" through His life (John 3:17).

Some scriptures promise salvation from other people and their evil intentions (Psalm 18:3). More often, God's Word promises salvation from the evil that is widespread throughout the world (Isaiah 45:22; Acts 4:12). Many times in the scriptures God offers to save us when this world is destroyed (Joel 2:31-32; 1 Peter 4:18). However, the most common use of the word may be "saved from the punishment we deserve" (Romans 5:9; 1 Corinthians 15:2; 1 Timothy 2:4).

Baptism has been a Christian symbol since the time of Jesus (Matthew 3:1-6). It involves applying water to Christians to symbolize their death to the old way of life (Romans 6:3-4) and their new life God provides (Galatians 3:26-27). Baptism, a sacramental "means of grace," seals one's intention to follow God (Acts 2:37-41, 8:35-39, 10:44-48). The Bible never defines how much water was applied or how. Therefore, the Church of the Nazarene considers immersion, sprinkling, and pouring all to be acceptable methods of baptism. Nazarenes also understand baptism to be a symbol of the new relationship God establishes with His people. Because of this, some Nazarenes choose to have their young children baptized as a symbol of their intention to raise their children in God's Church and their hope to see that their children choose God's ways when they are older.

Nazarenes, with other Wesleyans, believe in entire sanctification, when God's transforming work is complete and God's divine love that inhabits the Christian cleanses all sin from the heart (Romans 6:6, 1 Thessalonians 5:23). After we are born anew, we need the fullness of God's Holy Spirit in our hearts (Romans 8:6-8). When we make a complete commitment to Him, He cleanses our spirit, fills us with His perfect love, and gives us the power to live a holy life in obedience to Him (Romans 8:5, 9-11). Sanctification is God's will for all believers (1 Peter 1:15-16). Through the indwelling presence of the Holy Spirit, God enables believers to live a holy life and empowers them for life and service (Acts 1:8.) Nazarenes distinguish between a pure heart that is obtained in an instant through the infilling of the Holy Spirit and a mature character that is the result of growth in grace.

On the last night Jesus spent with His disciples before His death and resurrection, He shared bread and wine with them as part of the Passover meal (1 Corinthians 11:23-26). This sharing of the bread and wine is known as Holy Communion or the Lord's Supper. When Jesus shared the bread and wine with His disciples, the bread symbolized His body and the wine symbolized His blood (Matthew 26:26-29; Mark 14:22-25; Luke 22:17-20). The disciples understood this to mean that He was giving up His life (body and blood) for their benefit. The earliest records of the Church show that His followers regularly shared bread and wine together, reminding themselves that Jesus had died for them (1 Corinthians 10:14-16) and will come again. When Nazarene churches offer the Lord's Supper today, all believers are invited to participate regardless of membership in the church. The Lord's Supper is not appropriate for those who have not yet accepted the new life God offers (I Corinthians 11:28-29).

It is difficult to say that all the people in any group "always" or "never" act in certain ways. Within a church body, this is especially difficult, because God works with each believer a little differently. However, those who are Nazarenes have decided to follow God as best they can, and they intend to be more like God tomorrow than they were yesterday. Nazarenes actively encourage each other to become more like Jesus. We donate time, money, and energy to causes that will show God's love to the world (Matthew 25:31-40; Acts 2:45). We tell others about the ways God has worked in our lives, giving Him credit for the positive changes that the Holy Spirit has made (Acts 1:8). Nazarenes invite others to attend church services because we believe that God works through such gatherings to teach us more about himself (Acts 2:46; Hebrews 10:25). In short, we live our lives to show how God has made a difference (Matthew 5:13-16; Philippians 4:4-5).
