Open Air Preaching 
A Sketch of Its History

There are some customs for which nothing can be pleaded, except that they are very old. In such cases antiquity is of no more value than the rust upon a counterfeit coin. It is, however, a happy circumstance when the usage of ages can be pleaded for a really good and scriptural practice, for it invests it with a halo of reverence. Now, it can be argued, with small fear of refutation, that open air preaching is as old as preaching itself. We are at full liberty to believe that Enoch, the seventh from Adam, when he prophesied, asked for no better pulpit than the hill-side, and that Noah, as a preacher of righteousness, was willing to reason with his contemporaries in the ship-yard wherein his marvellous ark was builded. Certainly, Moses and Joshua found their most convenient place for addressing vast assemblies beneath the unpillared arch of heaven. Samuel closed a sermon in the field at Gilgal amid thunder and rain, by which the Lord rebuked the people and drove them to their knees. Elijah stood on Carmel, and challenged the vacillating nation with “How long halt ye between two opinions?” Jonah, whose spirit was somewhat similar, lifted up his cry of warning in the streets of Nineveh, and in all her places of concourse gave forth the warning utterance, “Yet forty days and Nineveh shall be overthrown!” To hear Ezra and Nehemiah “all the people gathered themselves together as one man into the street that was before the water gate.” Indeed, we find examples of open air preaching everywhere around us in the records of the Old Testament.
