It began among Aramaic-speaking Jews. Then it took shape in all the cultures surrounding Jerusalem – in Greek, Roman, North African, Ethiopian, Indian, Near Eastern and Arabic cultures. It expanded to the Franks, Scandinavia, the British Isles and on and on. To closely associate any culture with biblical faith, one must ignore the historical expansion of the Church.
The difference between faith and culture is also essential for an understanding of Galatians, Ephesians and Colossians. Paul speaks of the mystery —
And this is God’s plan: Both Gentiles [the ethne, comprising a multiplicity of cultures] and Jews who believe the Good News share equally in the riches inherited by God’s children. Both are part of the same body, and both enjoy the promise of blessings because they belong to Christ Jesus. Ephesians 3:6
Revelation and 1 Peter also would be difficult to understand were there no distinction between faith and culture.
