Our country has so many different religions in it. Most are good religions and some do good things all over the world. But when you cling to a “doctrine” that is written by men and then the religion clings to that doctrine as if it came from God’s…then your “church” has a problem. A doctrine can cause all kinds of problems because it is written by men and many of these doctrines don’t have a foundation that comes from the Bible.

Major Historical Doctrinal Conflicts

1. The Great Schism (1054 AD) – East vs. West

Context: The early Christian church was one body for about 1,000 years, but cultural, political, and theological differences grew between the Greek-speaking East (Constantinople) and Latin-speaking West (Rome).

Key Doctrinal Disputes:

Authority: Rome claimed the Pope had universal authority, but the East emphasized a “council of bishops.”

Creed: The West added the phrase “and the Son” (the Filioque) to the Nicene Creed, which the East rejected.

Outcome: Mutual excommunications — and the permanent split into Roman Catholic and Eastern Orthodox Churches.

2. The Protestant Reformation (1500s)

Context: Martin Luther and others challenged practices of the Catholic Church.

Key Doctrinal Disputes:

Salvation: Catholics taught faith + works + sacraments; Reformers insisted on “faith alone” (sola fide).

Authority: Catholics upheld Scripture + Tradition + the Pope; Protestants held to “Scripture alone” (sola scriptura).

Sacraments: Catholics had seven; most Protestants reduced this to two (baptism and communion).

Outcome: Europe fractured into competing denominations, sometimes violently (e.g., Thirty Years’ War).

3. Baptism & Communion Wars (1600s–1800s)

Even within Protestantism, differences exploded:

Baptists vs. Presbyterians over infant vs. adult baptism.

Lutherans, Calvinists, and later Evangelicals disagreed on what happens during Communion (real presence, spiritual presence, or symbolic).

These weren’t just minor quibbles — they determined who you worshiped with, married, or even trusted politically.

Modern Examples

Catholic vs. Protestant: Still divided on authority, Mary, saints, and the sacraments.

Evangelicals vs. Mainline Protestants: Clashes over biblical interpretation (literal vs. symbolic), morality, and social issues.

Pentecostals vs. Others: Disagreements over spiritual gifts like speaking in tongues.

Why Conflict Endures

1. Truth Claims: If one group is right, others must be wrong — and “wrong” can mean eternal consequences.

2. Identity & Loyalty: Belonging to a denomination often ties into family and culture, not just belief.

3. Power & Influence: Churches compete for members, resources, and legitimacy.

👉 So, doctrine causes conflict because it’s never just “intellectual.” It touches salvation, authority, community, and even politics.
