Baptists and the English Separatists

Baptist ChurchesAnglican Communion (Church of England, from which the Separatists came)

Institutional formation: A new church body is organised. Its members may continue much of what they received from the churches they came from.

The first Baptists were English Separatists from the Church of England. John Smyth's congregation in exile in Amsterdam adopted believer's baptism in 1609, and Thomas Helwys founded the first Baptist church in England, at Spitalfields, in 1612. Both early Baptist groups later came to practise immersion.

Baptists and Anabaptists

Baptist ChurchesAnabaptism

Common inheritance: Traditions with a shared heritage and no single act of separation between them.

The two traditions have separate origins, in Swiss and Dutch Anabaptism from 1525 and in English Separatism from 1609, but share believer's baptism and a free church separate from the state. How far Dutch Mennonites influenced the first Baptists in Amsterdam is debated by historians.

  • Believer’s baptism

    Baptism, usually by full immersion, follows a personal profession of faith.

  • Local autonomy

    Each congregation governs itself.
    Source

  • Religious liberty

    Early Baptists were prominent advocates of freedom of conscience.

Positions used in comparisons

Short, sourced statements that the Atlas compares across traditions. Where a tradition has no single teaching authority, the record says whose statement it follows.

God
'One and only one living and true God', revealed as Father, Son and Holy Spirit.
Source

Baptist Faith and Message 2000 (Southern Baptist Convention); Baptist confessions are not binding on other Baptists.

Christ
Christ is 'fully God, fully man'.

Scripture and authority
The Bible is God's inspired revelation and the standard for faith.
Source

Baptist Faith and Message 2000.

Sacraments and ordinances
Baptism is 'the immersion of a believer'; baptism and the Supper are church ordinances.
Source

Baptist Faith and Message 2000.

Varies This confession calls the Supper a symbolic memorial; Baptist teaching on the Supper is not uniform.

Church and ministry
Each church is 'an autonomous local congregation of baptized believers'.

Day of worship
'The first day of the week is the Lord's Day.'

  • Preaching and ordinances

    Services centre on preaching; baptism and the Lord’s Supper are usually called ordinances.

    The ordinances are checked; the centrality of preaching is not sourced.

    Provisional: broadly supported, but awaiting fuller checking.

Editorial notes on this record

  • Primary Reason for Split / Core Doctrine: Smyth’s 1609 baptisms were probably by pouring; immersion became standard in the 1640s.
  • Approx. Practitioners: 100 million has no source or date and seems high against Baptist World Alliance figures; check.
