Eastern Orthodox Presuppositionalism (EOP) is an ecclesiological epistemology, i.e. anti-catholic. In other words, according to EOP, the epistemological ground or cause of knowledge is said to be rooted in Eastern Orthodox ecclesiology, for EOP holds that the EOC is a precondition of intelligibility and knowledge. In contrast, Reformed Presuppositionalism (RP) is rooted in the Verbum Dei, with its epistemological ground seen to be God’s Word, and its epistemological consequence being unto and causative of ecclesiology. Put more simply, the RP position is that we can know the Church because of the transcendentally fundamental nature of God’s Word, not vice versa. The EOP position is that we know God’s Word because of the Church, thus causing the Scriptures and epistemology to submit to the Church (i.e. to ecclesiology).

Now, if the Church becomes a precondition for knowledge, then the Church becomes a viciously circular precondition for its own self-knowledge, and hence self-attesting, self-justifying, and finally irreformable, which is just what we see in the EOC. In other words, EOP epistemology ceases to be Bridal, ceases to be receptively and responsively confirmatory of the Bridegroom’s Word but rather determinative.
