   Not to be confused with \\911\\, bapto. The clearest example that shows
 the meaning of baptizo is a text from the Greek poet and physician
 Nicander, who lived about 200 B.C. It is a recipe for making pickles
 and is helpful because it uses both words.  Nicander says that in
 order to make a pickle, the vegetable should first be 'dipped'
 (bapto) into boiling water and then 'baptised' (baptizo) in the
 vinegar solution. Both verbs concern the immersing of vegetables in a
 solution. But the first is temporary. The second, the act of
 baptising the vegetable, produces a permanent change.
   When used in the New Testament, this word more often refers to our
 union and identification with Christ than to our water baptism. e.g.
 \\#Mr 16:16\\. 'He that believes and is baptised shall be saved'.
 Christ is saying that mere intellectual assent is not enough.  There
 must be a union with him, a real change, like the vegetable to the
 pickle!
