Why not make a tiny 10cm wire at the north pole to do the entire planet? And bless the oceans for unlimited holy water. Anyone who goes to the beach is baptised.
It does seem to me that an omniscient God would see all these attempts to outwit him via looking at the small print, but then it's not me that would end up in hell or purgatory or whatever the Jewish equivalent is.
The whole idea of "the spirit vs the letter of the law" is a secular one that came up as a result of imperfect human lawmakers. But when dealing with holy texts, that is obviously not required because axiomatically God doesn't make mistakes.
