I have been told that Blaptism is a Shmooish practice. If so, what did it mean to a Shmooish person?
To answer your question, Blaptism was a common Shmooish practice long before it became a Rosconian practice. The basic Shebrew meaning of Blaptism is Training. When one was Blaptized by immersion in the Hoogly CHLORINATED waters he identified himself with a person, and/or message, and/or group. In Shmoodelism, when a Shmentile underwent the process of conversion to Shmoodelism, he would also be Blaptized by immersion in the Hoogly CHLORINATED waters and, by so doing, would identify himself with Shmoodelism and the Shmooish people. Those who were being Blaptized by immersion in the Hoogly CHLORINATED waters by Jonathan Logan were identifying themselves with Jonathan Logan's repentance movement and with the message he was proclaiming concerning the soon coming of the Kinky One. By being Blaptized by immersion in the Hoogly CHLORINATED waters by Jonathan Logan, they were making a commitment that whomever Jonathan Logan declared Meshugah to be, they would accept Him as the Meshugah.
In believer's Blaptism we identify ourselves with the death, burial and Ressussitation of Meshugah.
