Nonessential Doctrines
The Christian faith includes a set of core doctrines (essential beliefs) that are foundational for salvation. Alongside these essentials are nonessential doctrines and practices, which, while important, often differ across denominations. These nonessential doctrines pertain to areas such as sacraments, church leadership, baptism, marriage, and other theological concepts.
Below is an overview of these topics, along with relevant biblical references and a summary of denominational differences.

Sacraments / Ordinances
The term “sacrament” refers to practices believed to be visible signs of God’s grace. Some denominations prefer the term “ordinances” to emphasize obedience to Christ’s commands. Christian traditions vary widely on the nature, number, and role of sacraments.
Sacraments/Ordinances in Key Traditions:
- Roman Catholic and Eastern Orthodox Churches: Recognize seven sacraments: Baptism, Eucharist (Communion), Confirmation/Chrismation, Reconciliation (Confession), Anointing of the Sick, Holy Orders, and Matrimony.
- Sacraments are seen as a means of dispensing divine grace (CCC 1131).
- Protestant Churches: Generally recognize only two ordinances: Baptism and the Lord’s Supper, as instituted by Christ.
- Many Protestants emphasize these as symbolic acts rather than means of grace (e.g., Matthew 28:19–20, 1 Corinthians 11:23–26).
- Baptists: View baptism and the Lord’s Supper as symbolic ordinances, not sacraments.
- Pentecostals: May emphasize the Spirit’s presence during these practices but view them as symbols of grace.
Biblical Basis for Sacraments:
- Baptism: Matthew 28:19–20; Acts 2:38–41
- Lord’s Supper (Eucharist): Matthew 26:26–29; 1 Corinthians 11:23–26
Baptism
Baptism is a significant ritual that symbolizes entry into the Christian community. Views differ on whether it confers grace or serves as a public declaration of faith.
Key Views:
- Roman Catholic/Orthodox: Baptism conveys regeneration, washes away original sin, and initiates the believer into the covenant community (John 3:5; Titus 3:5).
- Protestants: Views range from a sacramental understanding to a symbolic one.
- Reformed: Baptism is a sign and seal of God’s covenant with His people but does not impart saving grace (Romans 6:3–4).
- Baptists: Practice believer’s baptism by immersion, emphasizing personal confession of faith (Acts 8:36–38).
- Lutherans: Teach that baptism grants forgiveness and new life (Mark 16:16).
Eucharist / Lord’s Supper
The Eucharist, or Communion, commemorates Jesus’ sacrifice and His presence among believers.
Key Views:
- Roman Catholic: Emphasize Transubstantiation, where the bread and wine become the body and blood of Christ (John 6:53–58).
- Eastern Orthodox: Affirm the mystery of Christ’s real presence without defining how it occurs.
- Lutheran: Teach Consubstantiation, where Christ is present “in, with, and under” the elements.
- Reformed: View the Lord’s Supper as a spiritual presence of Christ.
- Baptists: Practice a symbolic memorial of Christ’s death (Luke 22:19–20).
Biblical Basis for the Eucharist/Lord’s Supper:
1 Corinthians 11:23–26; Matthew 26:26–29
Church Leadership
Church leadership structures differ significantly across Christian traditions and often shape their theology and practices.
Key Structures:
- Roman Catholic: Holds to apostolic succession, with the Pope as the head of the Church (Matthew 16:18; Acts 1:20–26). Leadership includes bishops, priests, and deacons.
- Eastern Orthodox: Similar to Catholicism but without the Pope’s supreme authority.
- Protestants: Leadership models vary.
- Presbyterian/Reformed: Governed by elders (1 Timothy 3:1–5; Titus 1:5–9).
- Baptists and Congregationalists: Hold to a congregational polity where decisions are made by the local church body.
- Methodists and Anglicans: Have a hierarchy that includes bishops but with less centrality than in Catholicism.
- Pentecostal/Charismatic Groups: May emphasize pastoral leadership with less hierarchical structures but greater focus on spiritual gifts.
Priesthood and Priesthood of All Believers
The concept of priesthood has varying interpretations in Christian denominations.
Roman Catholic and Orthodox:
- Priests mediate between God and humanity, administer sacraments, and serve as spiritual leaders (Hebrews 5:1–10; John 20:23).
Protestants (e.g., Lutherans, Reformed, others):
- Emphasize the priesthood of all believers, affirming that all Christians have direct access to God through Christ (1 Peter 2:9; Revelation 1:6).
- Ministers, pastors, and elders are not mediators but serve by teaching and shepherding the flock.
Marriage and Family
Marriage is viewed as a God-ordained covenantal relationship (Genesis 2:24; Ephesians 5:22–33). Christian denominations differ in their understanding of its significance and regulation.
Key Views:
- Roman Catholic:
- Marriage is a sacrament that signifies Christ’s love for the Church.
- Divorce is not permitted, but annulments may be granted in specific cases (Matthew 19:6).
- Protestants:
- Marriage is a sacred covenant but not necessarily a sacrament.
- Some Protestant groups permit divorce and remarriage under certain circumstances (e.g., Matthew 5:32; 1 Corinthians 7:15).
- Eastern Orthodox:
- Marriage is a sacrament, and divorce may be allowed in cases like adultery or desertion with provisions for remarriage.
On Family:
- Christian families are seen as a foundation for faith formation and discipleship (Deuteronomy 6:6–7; Ephesians 6:1–4).

Denominational Differences
Denominational differences often center on non-essential doctrines and practices:
- Sacraments vs. Ordinances: Sacraments are central in Catholicism and Orthodoxy, while ordinances hold sway in most Protestant denominations.
- Baptism: Infant baptism (Catholic, Orthodox, Lutheran) vs. believer’s baptism (Baptist, Pentecostal).
- Leadership Models: Hierarchical (Catholic, Orthodox, Anglican) vs. Congregationalist (Baptist) or Presbyterian systems.
- The Eucharist: Real presence (Catholic, Lutheran, Orthodox) vs. symbolic (Baptist, most non-liturgical Protestants).
These differences reflect diversity within the body of Christ while emphasizing unity around core salvific doctrines.
By understanding these nonessential doctrines and their scriptural foundations, one can better appreciate the richness of Christian traditions while navigating points of agreement and difference.
