4. To say that Baptists were not Protestants because they did not come out of the Roman
Catholic Church (since they were never a part of it) really begs the question of 17th century
Baptist origins. Clearly, both General and Particular Baptists derive from British Puritanism,
which was unquestionably a part of the Protestant Reformation.
5. To say that Baptists are not Protestants flies in the face of documented evidence to the
contrary.
The First London Baptist Confession (1644) title page states that this was a confession of
“churches which are commonly (though falsly) called Anabaptists.”
In the preface to the First London Confession, the Particular Baptists complained that they had
been charged “with holding Free-will, Falling away from grace, [and] denying Originall sinne....
All which Charges wee disclaime as notoriously untrue.”
The General Baptist Confession or Declaration of Faith (1660) was “set forth by many of us,
who are (falsely) called Ana-Baptists.”
In the preface to the Second London Baptist Confession (1677, 1688), we find comments
regarding the reason for adopting the Presbyterian Westminster Confession:
...and finding no defect in this regard in that fixed on by the [Westminster] Assembly, and after
them by those of the Congregational way [viz. The Savoy Declaration], we did readily conclude it
best to retain the same order in our present Confession.... We did in like manner conclude it best
to follow their example, in making use of the very same words with them both, in those articles
(which are very many) wherein our faith and doctrine is the same with theirs. And this we did, the
more abundantly to manifest our consent with both, in all the fundamental articles of the Christian
religion, as also with many others whose orthodox confessions have been published to the World,
on the behalf of the
protestants in diverse nations and cities; and also to convince all that we have
no itch to clog religion with new words, but to readily acquiesce in that form of sound words
which hath been, in consent with the holy scriptures, used by others before us; hereby declaring
before God, angels, and men, our hearty agreement with them, in the whole- some
protestant
doctrine, which, with so clear evidence of scriptures they have asserted (italics added for
emphasis).
It is worthwhile for anyone wanting factual data on the matter to consult this work by Gerald L. Priest from Detroit Baptist Theological Seminary.
