Not so:
Conversion requires both circumcision and mikva for the male: The Conservative Jewish process of conversion requires candidates, .....to appear before a beit din, or rabbinic court, to explain... to commit themselves to live as Jews, observe the Commandments, and raise any children with whom they may be blessed in the Jewish community and faith. Male candidates are required to undergo circumcision or, if already circumcised, to have a symbolic ceremony. All converts complete the rituals of conversion by immersing themselves in a mikvah."
I found this item through a skeptical mind and google. Thanks for the good advice.
As in primitive Christianity, immersion marked a significant turning, a physical affirmation of an inner choice and commitment. Ritual purification was also used by those involved in the Temple worship.
Bacchus on the cross
I'm not sure I get the point of this: Bacchus is depicted on a cross, therefore that's where some Jewish fisherman got the idea of Jesus on a cross? I'm assuming this is how it goes.
The cross was the means of execution throughout the Roman Empire, and the Romans were prolific when it came to Executions. That the idea came from this kind of idea or image seems far-fetched. If Jesus is seen riding into Egypt on a donkey, and in China, a family is pictured ridng on a donkey, does that mean the idea came from China? Did Moses get the idea of a great flood from the Australian aborigines? Or the Lummi tribe of Native Americans?
Probably that image of Bacchus getting crucified was the first-century logo of Alcoholics Anonymous.
You don't know what you're talking about. The mikva is for ritual purification. Of anyone unclean. Including converts who are considered unclean because of their background. Here, here, here.
I don't have the time or interest to cover the rest for you.
Don't go making claims like that unless you're willing to back them up.
Totally different concept than baptism, other than both involving water.
Actually, there are only a few differences. We only use it for conversions (and everyone, even those with Christian parents, are considered to require conversion), not the other uses they have. And we don't require total immersion in the sense they do (not even Baptists), and some don't require it at all. The washing symbolism is superceded by death and resurrection symbolism.
Unquestioning devotion to your faith rather than rational inquiry coupled with limited knowlege blind you from being able to think rationally.
My knowledge is evidently a little less limited than yours.
Funny that you ignored the picture of the dionysus/bacchus crucifiction image...
Without context, it's meaningless.
Google and a skeptical mind are your friend. At least, they are mine.
You should have tried Googling "mikva".
