Landmarkists hold a firm belief in the exclusive validity of Baptist churches and view non-Baptist liturgical forms and practices as invalid.
This perspective caused significant controversy and division within the Baptist community, leading to intense debates and numerous schisms.
The movement began in the American South in 1851, shaped by James R. Graves of Tennessee,[3][4] and Ben M. Bogard of Arkansas.
James M. Pendleton was a Baptist pastor from Kentucky whose article An Old Landmark Re-Set, a treatise against pulpit affiliation with non-Baptist ministers, gave the movement its name.
[10] Amos C. Dayton's major contribution to Landmarkism was the novel Theodosia Ernest (1857), which expressed religious issues and was first published in The Tennessee Baptist.
