The church is not a memorial for dead saints, or an institution that preserves tradition or of a singular culture. The church is the living and breathing embodiment of Jesus Christ to an ever changing world.
And while we as the embodiment of Jesus impact our world and cultures with the culture of the kingdom of God, we mustn’t forget that when people of their various colors and representations become fused into the body of Christ, they contribute their unique cultural identities as well. As a result, the body of Christ, while unchanging in purpose, is changing in appearance.
In the first century, the church was primarily Jewish. It soon consisted of Greeks. And as time went on, the Africans were included, then European, then American, now Asian, and on and on, the face of the church is changing. What a beautiful and marvelous thing!
So to answer the question of whether the culture of the church changes over time? Of course it does!
It is a welcome part of its maturity. The bride awaiting Jesus upon its return will be far from homogenous; she is a thing of beauty- a symphony of the diversity of his creation unified and beautified, reflecting the same dichotomy He shares with his Father and the Holy Spirit.
