Ezekiel 44:9 Thus saith the Lord GOD; No stranger, uncircumcised in heart, nor uncircumcised in flesh, shall enter into my sanctuary, of any stranger that is among the children of Israel.
Why didn't you also mention this part....nor uncircumcised in flesh, shall enter into my sanctuary. How do you make that work spiritually? That's not what the NT says.
Galatians 5:6 For in Jesus Christ neither circumcision availeth any thing, nor uncircumcision; but faith which worketh by love.
Colossians 2:11 In whom also ye are circumcised with the circumcision made without hands, in putting off the body of the sins of the flesh by the circumcision of Christ:
12 Buried with him in baptism, wherein also ye are risen with him through the faith of the operation of God, who hath raised him from the dead.
Keep in mind the context of Ez 40-48. It's about the house of Israel, and strangers in relation to them..
As far as those 2 passages I provided via the NT. Those would need to be understood spiritually. I don't see Ezekiel 44:9 being linked to those 2 NT passages.
