Then kindly explain why MOST Baptist Churches I have visited do not have elders.
Oh, they do have elders—their pastors and deacons—just not the nonbiblical Reformed scheme of "elders" on which you're apparently fixated.
A survey of Baptists' understanding of biblical elders as the church's pastors and deacons:
SBTS's Greg Wills, "The Church: Baptists and Their Churches in the Eighteenth and Nineteenth Centuries":
"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:
"These are both called Elders, 1 Timothy 5:17. . . .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."
In Charles Spurgeon's "The Sword and Trowel", 1866:
"the term elder is applied both to bishops and deacons"
Spurgeon's predecessors concurred:
William Rider,
Laying on of Hands Asserted, 1656:
"in the word Elders is comprehended all officers in the Church, with the Ministerial work also, . . . and so Elders is distinguished into several offices in the Church, as Bishops and Deacons . . . . Philip. 1.1 vers. where the Apostle writeth to the Saints, with the Bishops and Deacons: so Paul to Timothy writes of the qualifications of the Bishops and Deacons ; not Elders and Deacons ; you shall never in all the Scripture find Elders and Deacons expressed."
Benjamin Keach,
Gospel Mysteries Unveil'd [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)"
