When a person becomes a Christian they take on another family inheritance. Their chief identity is no longer what it was. “There is neither Jew nor Gentile, neither slave nor free, nor is there male and female, for you are all one in Christ Jesus. If you belong to Christ, then you are Abraham’s seed, and heirs according to the promise.” So Paul says in Galatians.
But this means there is a conflict. The old identity markers and the new are different. And it is not just the identity. It is the heritage. This is seen clearly by people who have grown up in a tradition different from the Judeo-Christian. It ought to be seen more clearly by those within a Christian heritage, because what our family has handed on to us may be a long way from the heritage that comes from Abraham via Christ.
That is one reason why we need to understand more deeply the heritage of Christ’s family so that we can adopt the values, traditions, customs, and behavioural characteristics that come from him, and change some of the ones we have inherited.
