It is interesting also the emphasis on "dedication" as a singular act or goal. But look in the article and see if you can find a single verse that describes this. Verses for baptism can be found, but not for an act of dedication.
I think Mt 16:24 is sometimes used which roughly describes the need for disciples of Jesus to be 'dedicated' (as an adjective). But there is no explicit instruction to perform a 'dedication' ceremony, nor any example in the NT of anyone doing this. Yet WT is insistent that this is a necessary prerequisite to baptism.
The Pharisees were also good at turning general instructions into specific ritual acts.
