In the OT, circumcision was a physical sign of the covenant between God and His people -it marked the people of Israel as set apart. But that’s no longer needed as Jesus is the new covenant. The nature of our covenantal relationship with God changes from external signs (circumcision) to internal transformation by the Holy Spirit.
If it was still necessary, then it would be a prerequisite to all church (body of christ) membership.
To the points about “hygiene and easier” -those have largely been debunked by modern science. And the roots of those myths are heavily tied to the western medical industrial complex. Also, there’s numerous cases where poorly executed circumcisions result in unpleasant sexual intercourse and long-term damage. In all, it’s not worth it. And for me, if my son really cares to be circumcised then he’s welcome to do it later if it wants.
