I would be interested to hear what they have to say about that. I mean particularly, that, "as a JW you must pledge allegiance to "the Spirited directed organization"
OK! I must admit I did not do the work, but here it is.
It was not until 1956 that baptism by the Watchtower Society became mandatory.
"Yes, one must be baptized again. Obviously, by any of such religious systems one was never in reality baptized "in the name of the Father and of the Son and of the holy spirit," because had he been so baptized he would have appreciated the authority and office of such true Higher Powers."
Watchtower 1956 Jul 1 p.406
The pre-baptismal process continued to become more rigid. Prior to baptism it became necessary for an interested person to answer 80 questions in front of 3 different elders.
"All who do get baptized are first given thorough instruction in basic Bible teachings, and thereafter (especially since 1967) elders in the congregation review such teachings with each baptismal candidate."
Proclaimers p.186
An important comment was made in 1955, something significantly contradicted in the arrangement introduced in 1985.
"A Christian, therefore, cannot be baptized in the name of the one actually doing the immersing or in the name of any man, nor in the name of any organization, but in the name of the Father, the Son and the holy spirit."
Watchtower 1955 Jul 1 p.411"
We do not dedicate ourselves to a religion, nor to a man, nor to an organization. No, we dedicate ourselves to the Supreme Sovereign of the Universe, our Creator, Jehovah God himself. This makes dedication a very personal relationship between us and Jehovah."
Watchtower 1966 Oct 1 pp.603-604
More unusual, the
Watchtower 1956 December 15 p.763 made the qualification that only those who had been baptised after 1918 needed to be re-baptised. Apparently that was the date when Christendom was officially rejected by Jehovah.
