The Reformed Church in America is wrestling with an interesting question in ecclesiology and church order: is there a place within the church for so-called non-geographic classes. Nongeographic classes are classes which are not formed around a geographic regional principal, but by agreement in theological perspective or a peculiar way that a congregation is shaped. The question central to this article is then: is there a place in Reformed churches for non-geographical classes? In answering this question, the following will be considered: a similar proposal from the Gereformeerde Bond in the Netherlands Reformed Church in 1998; the geographic-regional principle; the Walloon Classis; the Classis of Holland; the Reformed Church in America; Flying, diocesan and titular bishops and f.inally a conclusion. © 2013 Koninklijke Brill NV, Leiden.
