A few years ago I would have said no, but even though I never practiced as any kind of Xian, when I did a “reverse baptism” as part of another work to free me from all Xian programming, beliefs, and practices, it was a powerful experience (I was never actually baptised in a church), so I guess I must have absorbed a lot through the general cutlural saturation of this weird middle eastern zombie cult.
For that reason I’d go with yes, with the caveat “if you wish to,” because there’s power in rituals and in that moment when you draw a line under something and say “From this point forward, you are gone from my life.”
Something like this won’t take long, for example:
Or you could find some rites of blasphemy, or simply bathe yourself and consider it a cleansing of the past, the possibilities are limitless, it just has to be meaningful to YOU because we’re dealing at the level of ideas, emotions, and beliefs, so choose something that speaks to you.
