BeforeThereIs, Hebraic roots does not equate to Hebrew culture. Have you studied Romans? For the purpose of this thread Romans 11 is quite appropriate:
Romans 11:19-24
19 You will say then, "Branches were broken off so that I might be grafted in." 20 Quite right, they were broken off for their unbelief, but you stand by your faith. Do not be conceited, but fear; 21 for if God did not spare the natural branches, neither will He spare you. 22 Behold then the kindness and severity of God; to those who fell, severity, but to you, God's kindness, if you continue in His kindness; otherwise you also will be cut off. 23 And they also, if they do not continue in their unbelief, will be grafted in; for God is able to graft them in again. 24 For if you were cut off from what is by nature a wild olive tree, and were grafted contrary to nature into a cultivated olive tree, how much more shall these who are the natural branches be grafted into their own olive tree? NAS
The wild olive has tried to replace the natural olive.
