William Rider (first pastor of what came to be Metropolitan Tabernacle Baptist Church, London) in 1656:
"in the word Elders is comprehended all officers in the Church . . . and so Elders is distinguished into several offices in the Church, as Bishops and Deacons"
Benjamin Keach (prominent signer of the 1689 LBC) in 1701:
"Moreover, the Deacons are to be helps in Government. Some think Paul calls the Deacons Elders, when he speaks of Elders that rule well [I Tim. 5:17] (as our Annotators observe)"
SBTS's Greg Wills, "The Church: Baptists and Their Churches in the Eighteenth and Nineteenth Centuries":
"Many of these held that the pastor and deacons jointly constituted the eldership. South Carolina’s Tyger River Baptist Association, for example, judged in 1835 that "the eldership of the church" consisted of "the ministers and deacons."
Shaftsbury Baptist Association, 1804 Circular Letter:
"[Bishops and Deacons] are both called Elders. . . .By these Elders, we understand Bishops and Deacons; and we have not learned from the scriptures, but that these two are the only officers to be ordained in the Christian Church."
American Baptist Magazine, 1829:
"The term elder was, probably, a general term equivalent to our word officer; and thus it could be applied to a pastor, or to a deacon ; and the elders of a church included the pastor or pastors and the deacons."
The Sword and Trowel, 1866:
"the term elder is applied both to bishops and deacons. This might be supposed to prove too much, as though there had been no separate offices in the Church. It goes, in fact, just to the extent we require, that distinct officers were recognized by the Church, but they were lovingly blended together. There was no contention about a name as expressive of an authority, which it would have been sacrilege for others to invade."
