Why the women caught in adultery isn't found in the Peshitta

[Rob]

The Mosaic laws aren't for everyone (meaning not every law applies to men, women, priests, gentiles etc), and not for every time period. When Israel was in exile; for example; they could not run temple services but were still required to hold fast the the laws otherwise.

Salvation isn't dependant on the law, but the law teaches us what sin is. The regulations Jesus "changed" were actually made harder.
