Ezekiel 44:7
In that ye have brought into my sanctuary strangers, uncircumcised in heart, and uncircumcised in flesh, to be in my sanctuary, to pollute it, even my house, when ye offer my bread, the fat and the blood, and they have broken my covenant because of all your abominations.
Bringing outsiders who are uncircumcised in heart and uncircumcised in flesh into the sanctuary to stand there while the bread, the fat, and the blood are offered pollutes God's house, even His own dwelling. That bringing in breaks His covenant by means of abominations, and it establishes that holiness and faithfulness are required in the service of His house. The same charge reaches those who claim to receive Bible truth yet refuse to live it, for while they are counted as circumcised by profession they are still uncircumcised in behavior, ranking themselves with the greedy and continuing to live as wrongdoers. Instead of using what was committed to them with loyal service, these professed believers turn their entrusted privileges and abilities to unfaithful ends. They will not escape when judgment comes but will be cut off together with the uncircumcised.
