The Temple is a House of Prayer for Everyone (Who is Circumcised in the Flesh)

One Law Believers have to accept that being obligated to One Law means being obligated to physical circumcision.  Isaiah does indeed say that the Temple will be a House of Prayer for all peoples (Isaiah 56:7) but let's not forget what Ezekiel says:

"Thus saith the Lord God:  No alien, uncircumcised in heart and uncircumcised in flesh, shall enter into My sanctuary, even any alien that is among the children of Israel" (Ezek.  44:9)
