Romans 2:28

For he is not a Jew - A genuine member of the Church of God, who has only an outward profession.

Neither is that circumcision - Circumcision is a rite which represents a spiritual thing, viz. the change and purification of the heart, as may be seen, Jeremiah 4:4 , Jeremiah 4:6 , Jeremiah 4:10 ; Jeremiah 9:26 ; Ezekiel 44:7 , Ezekiel 44:9 .
