Is Reformed Worship Eurocentric?

If the immediate roots are European, are there foundational roots in the Patristic church that are non-European? If that is indeed the case, how does this affect our outlook? Calvin claimed that his “Form of Church Prayers” was “According to the Custom of the Ancient Church.” Hughes O. Old’s Patristic Roots is dedicated to evaluating and in the end substantiating Calvin’s claim. Reformed Worship, he demonstrates, is more an expression of the convictions of the Fathers than the culture of the Reformers. At stake is the normativity of Reformed Worship.
