Bob L. Ross wrote a paper about Landmarkism in the 60’s. In the closing words, he shares this personal note:
“Those who know me know that I have been a consistent Landmark Baptist in faith and practice. I have written articles, tracts, and booklets in which I support those views which are described by the term Landmark. Also, I have practiced these principles, rebaptizing those who were immersed by someone other than a Landmark Baptist administrator, re-organizing churches if they did not start from another Scriptural (Landmark) church, and refusing to recognize the validity of any baptism or church organization that did not originate upon the authority of a sound Baptist church.
As a result of these views, I can now see how I have contributed to a bad type of sectarianism, although I was honest all the while in thinking I was only doing what was right in the sight of God. I have said things against Spirit-blessed men, simply because they were not Landmark Baptists. I have regarded God-blessed churches as unscriptural simply because they were not in the Landmark succession. I know I have done much evil; I only hope the Lord will be pleased to allow me to undo some of it. And I hope that you, dear reader, read this article with an open mind to what I have to say. I assure you that I was a Landmark of Landmarks in what I believed. I do not believe you could now be any more a Landmark Baptist than I once was. It was through opening my mind and heart to the plain facts of the Bible and history that Landmarkism was removed from me. I hope you will judge with an open mind, also. Be honest with yourself and with the truth. It is always best to simply take the truth and let our own ideas go, regardless of the cost. When a person changes or relinquishes his views out of good motives and respect for the truth, he is only doing what all good, sincere men should do. C. H. Spurgeon once made a remark about such changes: “To confess you were wrong yesterday is only to acknowledge that you are a little wiser today; and instead of being a reflection on yourself, it is an honor to your judgment, and shows you are improving in the knowledge of the truth” (New Park Street Pulpit, 1:310).”
