Quoting from Old Landmarkism: What Is it? by J. R. Graves, pp. 116-117, "And if they be invited to the funeral of any pedobaptist [infant baptizer], they will go to the house and accompany the corpse with the rest of the people to the door; but there they retreat--they call it the Steeple House....They did not visit their Steeple Houses, because they did not believe God was worshipped in them, but His holy name and service profaned by the priests, by their senseless and popish forms and ceremonies; for Christ had said, 'In vain do they worship me who teach for doctrines the commandments of men.' Baptists of that day thought they would be regarded as countenancing, in some sense, the priests of the church of England should they attend their administrations. And if we will only consider the influence of acts closely, we shall be forced to conclude that they acted consistently."
1. This was a day in 1587 when true Baptists separated themselves from false worship
2. True Baptists at that time did not have steeples on their houses of worship
3. They were Landmarkers in the sense they considered carefully the results of their actions before doing anything that would give others the idea they approved of false religion in any way
4. Landmarkers today should practice consistently - it is not enough to preach the truth and then practice like a Protestant congregation.
