The Second London Baptist Confession of Faith, compiled in 1677 and revised in 1689, is an intriguing historical document. In it the Baptists chose to "copy" the Westminster Confession of the Presbyterians, and then rewrite parts where they differed.
The link below will take you to "A Tabular Comparison of the 1646 WCF and the 1689 LBCF". This comparison places the two confessions side by side, highlights in red "major" differences and in blue "minor" differences. The compiler freely admits that sometimes the line between 'major' and 'minor' differences is a fine one and may include subjective judgments. You might also want to know that the compiler is not a Baptist, but is in the Reformed tradition.
Such a comparison can be helpful in understanding the SLCF. The fact that they chose to copy the Westminster Confession speaks to one thing. The changes they made can clue us in to their thinking and how it differed from the Presbyterians in the areas where they made changes.
