It was my understanding that once was all anyone needed as for ever after one was in the fold as it were. All religions are rife with pointless symbolism and ceremony, all of which is ludicrous, laughable and just plain whacked-out screwy-silly. I remember one such affair at the "Christian Fellowship" to which my wife and kids dragged me for a year until I finally rebelled and made the final leap into full-blown atheism. It was at the outdoor, former gold fish pond for the estate that became a very regal home for the equally whacked-out bunch of Pentecostal mob and some of the younger crowd was going under.
One lass, quite lovely and well put together indeed was wearing her best, I suppose, dunking gear was taken backwards into the water as normal. As she was brought back up, her water-soaked dress and the flimsy garments thereunder were rendered almost transparent, even to her, obviously very cold nipples that were standing at attention in stark relief and quite visible through the material; quite the entertaining show it was.
i got dipped once and it is a pressure I think religious parents put on the kids without really realizing it. To some degree it could be considered emotional child abuse but then I see religious as abusive to all ages too.
I was baptized twice - sprinkled in the Moravian church, and dunked in the Church of Christ; then later confirmed/first communion in the Catholic church. All of the above were to be a member of a community.
Thought third time was a charm but it didn't stick. Oh well.
I was raised Catholic, so one baptism. You're baptized early (the first coupe of months), then you "re-affirm your belief" at Confirmation, which is just a baptism with oil instead of water (in about the sixth or seventh grade age or so). Confirmation for Catholics is like that, you have classes of 20+ children doing all the chants and you get blessed by the Bishop and BOOM! you're a full-fledged Catholic before you're in High School or formed your own opinion or thought. I think the classes are smaller if you convert as an adult. But the first baptism is usually just one or maybe two children, pretty individualized. At least here in Mobile it is.
Three times? I was so young the first time that I hardly remember it. The second time I MIGHT have been 9, at most. The third time, maybe 15? Right after I met my first husband, anyway. After that, I figured that if it was going to work, it would have by then.
